Small Lab freezer for single-use technology

Biopharmaceutical manufacturers are increasingly utilizing single-use technologies for cold storage, shipping in the cryogenic temperature range and the transfer of biopharmaceutical substances and reagents under strict temperature control. The advantages speak for themselves:

By abandoning cost-intensive, outdated, and bulky lab equipment such as auto defrost solid door upright freezers, conventional manual defrost chest freezers, and ultra-low temperature freezers, manufacturers can save considerable amounts of USD and increase productivity considerably for each cu ft of plant space.

Single-use technologies, and single-use bioprocess containers in particular, require little storage space, which makes them a cost-effective solution. Additionally, bags of different sizes are freely available on the market and, where required, established and standardized quality tests are available to be conducted before filling and use.

Recently, the COVID-19 pandemic highlighted a weak point in the life science and biopharma business: refrigeration, freezing and cold temperature technology in general. With the need to manufacture massive amounts of vaccine vials with unprecedented storage requirements, the bottleneck of vaccine storage and transport emerged. This situation challenged innovative companies to develop benchtop solutions to overcome lab refrigerators and small lab freezers.

But the advantages of single-use technology do not end with the storage: The entire handling of the logistics process for biopharmaceutical liquids is fool-proof, especially when compared to the utilization of stainless-steel tanks, Cryo vessels and other traditionell alternatives. With the use of single-use technologies, cleaning, storage as well as complicated logistics can practically be omitted.

Where the water volume as well as chemical detergents required when using stainless-steel solutions are significant and far from being sustainable, single-use technology is leading the way in terms of sustainability.

All these factors apply to established manufacturing as well as the production of small batches conducted in labs or for study purposes with conventional methods such as chromatography, countertop centrifuges, PCR, pipettes, and electrophoresis.

Avoiding product loss by single-use-bag protection

The advantages of compact plate freezers over laboratory freezers in pharma

Humans are simple beings. So it seems just plausible to use a general purpose compressor fridge or lab freezer in pharma for freezing liquids such as culture media. But things are not always as simple as they may appear. While the use of laboratory refrigerators and low freezers may be logical, the outcome is far from the optimum and usually unsatisfactory. Traditional defrost freezers have disadvantages that can be clearly measured:

  • Unreliable thermostats, lack of digital controls, timers, microprocessor control, touchscreens
  • A lengthy freezing process for liquids
  • The formation of relatively big crystalline structures caused by the slow and not very homogenous freezing process, which are the cause of frictions that lead to the destruction of valuable proteins. Up to 20% of proteins can be destroyed like this. Effect: After thawing, the substance has lost a considerable amount of its original concentration, thus dropping in value.

At first it may feel unfamiliar to place a microplate or filled single-use bag in a compact plate freezer, which seems to resemble a toaster rather than a freezing device.

However, appearances do not matter as long as the outcome does not fail to convince:

  • The speed of the freezing process is multiplied: Thanks to the close contact of the freezing plates and the liquid there is no more need to freeze air used for isolation. The cold gets directly transferred, thus saving time and energy.
  • The shock-like freezing retains the quality of the substance, from small molecule drugs to enzymes and monoclonal antibodies. Due to direct contact with the freezing plates on both sides, the container is frozen consistently and evenly, as seen in the image. A condensed line is visible in the bag’s mirror axis, indicating a homogeneous freezing process.

FAQ

What is a lab freezer?

Lab freezers are devices with the purpose to keep products at temperatures between 10 and -40 °C. RoSS.pFTU Lab Scale is a plate based freeze-thaw unit for labs, showing perfect features for laboratory studies or cell and gene therapies.  

What is a medical freezer?

Medical freezers are specifically designed to store medical substances. Since these goods come with specific needs, the according devices have to meet several criteria that set them apart from ordinary household freezers.

What is the difference between a blast freezer and a plate freezer?

While blast freezers use cold air that is blasted on products that are yet to be frozen, plate freezers work via direct contact between the cooled plates and the products.

What is the difference between a lab freezer and a fridge for lab?

Both the lab freezer and the fridge for labs work with extremely low temperatures. But while lab freezers are devices that are made to cool down specific goods to these low temperatures, fridges for labs are designed for the storage of the frozen goods in the appropriate temperature range.

Single Use Support has created both the freeze/thaw platform RoSS.pFTU (with high-performance plate freezers in different sizes) and the RoSS.FRDG, which is a specialized freezer for labs that is scalable, stackable, comes with high storage density and great temperature stability.

What temperature is a lab freezer?

While low temperature freezers can achieve cooling temperatures in a range between around -10 and -45 °C, ultra cold freezing requires lower temperatures, between -60 and -80 °C.

What are the costs for a lab freezer?

RoSS.pFTU lab scale is a freeze thaw unit and the perfect solution for clinical studies conducted in laboratories. The platform freezes and thaws to stable results and is therefore not comparable to a typical laboratory refrigerator, just keeping cold temperatures. We can provide costs in a quote upon request. Please also consider the possibility for lab freezer rental. 

Is there the possibility for lab freezer rental?

Our lab freezer is now available for rent.  Test the freeze-thaw unit for up to three months. You will get the rent paid refunded if you decide to purchase the platform.
