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By abandoning cost-intensive, outdated, and bulky lab equipment such as auto defrost solid door upright freezers, conventional manual defrost chest freezers, and ultra-low temperature freezers,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.

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.

Plate freezing: best approach for freezing biopharmaceuticals

Plate freezing is a process where a product’s temperature is reduced by the means of contact with cold surfaces. Thus, a defining step in the freeze-thaw process for conservation, with several advantages for biopharma.

Single-use technology

Single-use technology & the implementation in biopharma

Single-use technologies, which reduce the risk of cross-contamination of high-quality bulk drug substances, are becoming increasingly popular in the pharmaceutical industry. You can find out the reason for this in the blog post!

Freezing & Storing biopharmaceuticals at -80°C and below - The best economical choice

In this publication we show that the intital price can be deceiving and there are significant additional costs during ongoing usage in the long term. Plate freezers ensure a complete, consistent, and fast freezing (and thawing) to ensure the quality of your high-valued drug substance is maintained, and through simple lifecylcle analysis they outpace conventional options regarding total costs.
