3 Ways to Make ULT Freezers Save Energy

Ultralow temperature (ULT) freezers can consume a lot of electricity. Estimates from the US Department of Energy indicate that conventional ULT freezers consume between 16 and 22 kilowatt-hours (kWh) of electricity daily, which is about the same as the average US household. If your lab has more than one of these freezers, your energy use will be staggering.

All Lab equipment is designed to sustain specific conditions for operation, either consistent temperatures when it comes to Cold Storage, Ovens or Incubators or speed for centrifuges etc.

3 Ways VR and AR Can Make ULT Freezers Cooler

Ultralow temperature (ULT) freezers produce very cold temperatures of up to -86º C. Now, with the technologies of virtual reality (VR) and augmented reality (AR), ULT freezers can be even cooler.

North Sciences Jean Fallacara writes on Artificial Intelligence for Lab Monitoring in this article published in Lab Manager.

A typical day in your lab may involve walking near a freezer, or a room full of them. These, especially ultralow temperature (ULT) freezers, are crucial pieces of equipment in any biological lab. They allow specimens to be preserved for as long as several years without loss of quality and viability.

2 Powerful Things AI Can Do For Your Lab 

Artificial intelligence (AI) has gone far since being a staple of science fiction in the 20th century. Now, AI is a science fact, and it is quickly gaining ground. Modern AI can write, paint pictures, and compose music, among other remarkable things.

We are chillin' in Booth 812 at NECANN Boston! Stop by to learn more about hydrocarbon and ethanol cooling. 

The typical refrigerator or freezer uses a refrigerant to produce cold temperatures. Refrigerants make use of a cycle of evaporation and condensation to cool the contents inside. Evaporation is an endothermic process, which absorbs heat from the surroundings. The result is a cool refrigerator interior.

A biobank is a collection of biological samples and the data associated with them. The samples usually originate from humans and can include tissue samples, blood, and bodily fluids. Biobanks are highly valuable tools in medical and health research.

Refrigerators Do Not Produce Cold

If you have a lab refrigerator or an ultralow temperature (ULT) freezer, what is its temperature? ‘Cold’ is the first thing that will come to mind. And yes, it is true that refrigerators and freezers are cold.

ULT stands for ultra-low temperature. ULT freezers operate in the range of -40 to -86ºC, hence the name. They come in a range of sizes – most ULT freezers are upright freezers that resemble large refrigerators, while some are so small they can fit on a tabletop. There are also chest ULT freezers that look like the freezers used to store meat in restaurants. There are even walk-in ULT freezers with much larger capacities.

Biobanking is an important tool for enhancing medical research and scientific knowledge. Simply put, biobanking is the process of collecting biological samples from a human subject for use in research purposes.

The right kind of lab equipment can make a world of difference and save you hefty maintenance and repair costs later on.

The Covid-19 vaccines have been hailed as a remarkable medical feat as they were developed under ten months since the coronavirus pandemic began.

Traditionally, vaccines have taken from around 10-15 years to be developed. The collaboration of governments, medical companies, and other interest groups has helped ensure that the Covid-19 vaccines roll out under record time.

To say that the last year has been challenging would be an understatement. As health officials advised the public on ways to prevent the spread of the virus and the authorities started lifting lockdowns, the news of new strains of the virus emerged.

Ultra-low Temperature (ULT) freezers are designed to provide with low temperatures, going as low as -80°C. But simply reaching this temperature is not a desirable asset, as the time it takes for the device to get to that level is equally important. This metric is referred to as pull-down time.

As labs require quick and efficient cooling, ULT freezer manufacturers are focusing technology towards methods that ensure fast cooling down times as well as temperature uniformity of the vessel.

When it comes to a large investment like a ULT freezer, it is important to acquire the best option. Different varieties are available on the market, all suitable for different operations and purposes.

Preservation of samples is the utmost responsibility of any laboratory or pharmaceutical facility, and thanks to advancements in science and technology, the unique invention of Ultra-Low Temperature or ULT freezers has become an excellent storage choice for lab samples and specimens.

While ULT freezers are rugged and reliable, and can go through wear and tear over time. With the excessive usage they’re put through, it isn’t uncommon for the ULT freezer’s compressor, door/gasket, or condenser to stop working properly.

Luckily, they’re usually easy to diagnose and fix.

Ultra-low temperature freezers, also known as ULT freezers operate at extremely low temperatures, designed to keep items preserved for longer periods of time. They are long-lasting installations that require minimal maintenance while offering good value for money. Here’s why all laboratories should invest in a ULT freezer.

If you’re looking to buy a top-tier and highly-advanced Ultralow and Ultrafast temperature freezer to meet industry requirements, Z-SC1 has just introduced the perfect ULT freezer—the TWINCORE ECO—with over 50 technological upgrades.

As the cold weather rolls in, health experts in the United States are encouraging people to get flu shots. The influenza virus mimics many of the symptoms of COVID-19 and is problematic for multiple reasons:

More than 11 million people in Canada have been tested for COVID-19, and thousands more are tested each day. To maximize the accuracy of these results, significant care must be exercised while handling and transporting these samples.

Countries around the world are in a multibillion dollar race to develop a COVID-19 vaccine. Meanwhile, COVID-19 specimens sent to the Centers for Disease Control and Prevention (CDC) are carefully stored and collected for diagnostic purposes. This requires proper cold storage solutions that store specimens at the right temperature, ensuring they’re viable for testing and research.

At the moment, 40 different vaccines for COVID are under test and trial. While we haven’t reached an endpoint with any of them, we soon will. One vaccine being developed by the University of Oxford is looking very promising and is in advanced stages of its development.

Since we’re nearing the closure of these trials and might have a vaccine soon, it’s time we also begin worrying about other matters: such as where to store these vaccines once we have them?

What good is an advanced technology if you can’t use it? At the moment, we’re still pretty far from intelligent machines like those who can make their own calculated decisions. The most we ever got to was bots conversing in gibberish.

For now, humans will have to do with manual controls. And sometimes, calibrating those controls can be a real deal.

While we all know platelets as the component of blood that helps it develop clots upon wounds, there’s more to these biconvex discoid structures. When it comes to storing them, they must be isolated from blood and stored separately, with plasma. The time period of their storage is usually five days. Over time, they undergo a number of storage changes, which makes their storage much more demanding.

Large biomedical corporations can make do with larger, more energy-consuming freezers—but what about small-scale biomedical research labs or clinics? Where do you store your samples and drugs?

Medical-grade refrigerators are indispensable in the world of modern medicine since they play a critical role in safekeeping biological samples, vaccines, medicines, and other medical supplies.

Pharmaceutical-grade lab refrigerators in research centers and medical facilities store temperature-sensitive biological samples and vaccines. Failure to follow the best preventive maintenance practices of essential lab equipment can lead to sub-optimal performance, or worse, reduced potency and compromised the integrity of sample materials.

Immunization is one of the biggest cost-effective public health interventions to date. WHO estimates that nearly 2 to 3 million deaths are prevented each year through immunizations against diphtheria, tetanus, and pertussis vaccine (DTP).

Collecting and preserving biological samples for future examination and analysis is fundamental for pharmaceutical and biological research.

Ultra low temperature (ULT) freezers are essential to any medical facility or lab environment. They play a crucial role in preserving temperature-sensitive biological samples.

Here’s what you need to know before buying a lab freezer:

Ultra-low temperature freezers typically operate within the -60°C to -86°C range. These are used in medical facilities to store biological samples like plasma, blood, enzymes, or organ tissues.

As with any critical piece of lab equipment, lack of maintenance can lead to sub-optimal ULT freezer performance—this is detrimental to the samples stored in the freezer.

inTEST Corporation (NYSE American: INTT), a global supplier of precision-engineered solutions for use in manufacturing and testing across a wide range of markets including automotive, defense/aerospace, energy, industrial, semiconductor and telecommunications, announced today its thermal segment subsidiary, inTEST Thermal Solutions, is introducing an all-new brand identity that includes new logos, colors and designs to unify and visually reinforce the synergies between its three core product lines – Temptronic, Sigma Systems and Thermonics.

Vaccine, drug, tissue, serum, and other biological sample preservation requires biopharmaceutical refrigerators with precise temperature and humidity control.

The global biomedical refrigerators and freezers market is predicted to amount to nearly 5 billion USD by 2026.

The reason why the pharma cold chain is a billion-dollar industry is simple: pharmaceutical and healthcare industries are required to deliver high-quality products. For that, they need state-of-the-art cold storage solutions to preserve biological samples and maintain their intended efficacy.

Ultra low temperature freezers are used in a variety of facilities, including biobanking, academic institutions, clinical and hospital settings, biotechnology companies, pharmaceutical laboratories, and more.

ULT freezers offer safe and controlled preservation of biological samples including, reagents, proteins, DNA, PCR and sequencing nucleotides, antibodies, enzymes, and small molecules.

Every facility has its unique cold storage needs when it comes to medical refrigeration. Biomedical research laboratories need refrigeration to store critical samples at precisely controlled temperatures, while medical clinics may need it to store medication, vaccines, blood bags, or organs for transplant.

The environmentally friendly ECO series ThermoStream® temperature forcing systems, introduced last year, using less energy with very low audible noise will save users from additional maintenance costs under the EU F-Gas regulation for refrigeration systems. Beginning January 1, 2017, the EU 517/2014 regulation requires annual leak checking for all refrigeration systems that exceed a gas charge limit.

An environmentally friendly series of Temptronic® ThermoStream® temperature forcing systems that use one-third less energy with very low audible noise has been introduced by inTEST Thermal Solutions. The ECO Series temperature test systems operate on a low, 20-amp circuit and incorporate the company’s proprietary WhisperStream™ technology providing quiet, smooth-sounding operation at 56 dBA. The ECO Series is designed with the laboratory environment in mind where audible noise and heat dissipation are of concern.

Two benchtop systems for thermal characterization of ICs, including high-Watt emitting devices, have been introduced by inTEST Thermal. The Temptronic® ThermoSpot® consists of a highly responsive benchtop temperature forcing unit that feeds a thermal probe head through a flexible umbilical. The thermal probe is designed with interchangeable thermal heads to mate directly to an IC or other device under test creating a highly efficient thermally conductive path to quickly induce temperatures to the device, even under power.

inTEST Thermal Solutions (iTS) has designed a multi-zone thermal plate for hot/cold temperature cycling of microwave signal amplifiers used in satellite data communications. The heart of the amplifier is a travelling wave tube (TWT) and power supply. In their space-borne environment, TWTs are exposed to extreme temperatures that influence the strength and stability of their magnetic field and can adversely affect their RF signal output. Rigorous thermal stressing of TWTs is required to characterize RF signal outputs and ensure trouble-free operation after deployment.

The integration of a temperature controlled thermal platform with the Agilent B1506A Power Device Analyzer has been introduced by inTEST Thermal Solutions and Agilent. The newly designed hot plate permits automated control of platform temperature, from enclosure ambient to 250 °C, for characterization of power devices such as IGBTs and MOSFETs.
Power devices generate heat, which is why manufacturers mainly test in high temperature environments. Conventional thermal platforms did not fit within the fixture area of the analyzer, giving rise to inTEST Thermal’s design.

A temperature control system for high-temperature testing of ICs, transceivers, and PCBs has been introduced by inTEST Thermal Solutions. The Thermostream® ATS-750 delivers clean dry air from -90 to 300°C to support growing demands for testing electronics that need to operate at higher temperatures. With temperature transitions up to 15°C/sec, the ATS-750 provides the horse power to reach a wide temperature range quickly, increasing throughput for thermal cycling and failure analysis.

A replacement controller for Sigma Systems thermal chambers and plates has been introduced by inTEST Thermal Solutions. The TSR controller matches both size and programming syntax of legacy C3 and C4 controllers while adding the following enhancements:

inTEST Thermal Solutions has launched the a comprehensive line of precision temperature forcing systems, the ATS-Series ThermoStream® systems. With temperature range extremes as high as 300ºC (570ºF) and as low as -100ºC (-148ºF), countless test and conditioning applications can now be solved with a compact, precise, and portable system.
