B Medical Systems' Contact Shock Freezers are designed to help blood banks and blood transfusion centres to fast freeze plasma in compliance with the medical standards. They provide one of the shortest cooling times available on the market, with the largest model being able to cool down 48 bags of 350ml to a core temperature below -30°C in approximately 26 minutes. This is well within the 60-minute range recommended by the EDQM.
Classified as medical devices Class II(a), both models – CSF61 and CSF101 – rely on a unique technology. This patent-pending technological innovation was developed as a result of 40 years of experience in medical refrigeration, including more than 15 years in contact shock freezing.
B Medical Systems' Contact Shock Freezers will provide you with high quality plasma, significant energy savings and complete traceability of your fresh frozen bags.

How to freeze and store COVID-19 convalescent plasma
With the COVID-19 pandemic affecting lives across the world, clinical trials have been steadily on the rise. One of the forerunners in these trials is the convalescent plasma (CP) therapy, involving transfusion of plasma from the COVID-19 recovered patients. As this therapy involves the use of a temperature sensitive product human plasma, the ability to store it at the mandated temperature is critical to serve the therapeutic purpose.
This paper delves into the history of CP, some of its storage protocols, and highlights freezing and storage solutions that preserve the best quality of plasma.
Understanding the optimal performance of contact shock freezers
Due to the massive volumes of blood products that a typical Blood Centre collects and supplies on any given day, a thorough understanding of the operational capabilities of the capital equipment is one of the key attributes for effective and efficient inventory management of the blood components. This white paper estimates the freezing capacity of the Contact Shock Freezer from B Medical Systems against various operational scenarios in a blood centre on a daily basis to help optimise the operational efficiency.
Energy efficient contact shock freezing
B Medical Systems Contact Shock Freezers, CSF61 and CSF101 are designed for the freezing of blood plasma, biological and pharmaceutical preparations to a core temperature of -30°C in a short time. At the same time, utmost care has been taken to make sure that both models are optimized for energy efficiency, thereby further benefiting customer needs in the long term from an operational perspective.
FDA Regulations on Electronic Records - FAQs and Applicability to Temperature Monitoring Systems
In this whitepaper, B Medical Systems explains the scope of usage and applicability of 21 CFR Part 11 in day-to-day operational scenarios and discusses how remote temperature monitoring systems, integrated to medical devices such as lab refrigerators or freezers, comply with the standards set by the FDA regulation. Amongst others, °B Connected – a remote monitoring solution developed by B Medical Systems that generates electronic records – meets the technical controls of 21 CFR Part 11 regulation, thereby providing an extra layer of assurance for FDA submissions.
