AABB has long required that plasma be stored at a temperature of -18ºC or colder. Like all blood storage devices, plasma freezers must have the capacity and design to ensure that the proper temperature is maintained. In addition, the temperature must be monitored continuously and recorded at least every 4 hours.
Plasma storage freezers from Helmer Scientific have been helping blood centers and transfusion services meet these requirements for many years. They operate at -30ºC, ensuring that plasma products stay well below -18ºC. They are designed with built-in continuous temperature monitoring and a chart recorder that constantly records the temperature inside the unit. In addition, they can be easily monitored by any central or remote monitoring system that a facility chooses.
A recent development is making it even easier for facilities to adopt the use of Helmer plasma storage freezers. Long available with a voltage of 208/230, the freezers are now available in 115 volts. This means that facilities that are not equipped with a 208/230 volt power outlets in the location where they want to place the freezer do not need to have one installed. A standard 115 volt outlet can be used instead, increasing convenience and lowering the cost of ownership.
Plasma storage freezers from Helmer Scientific offer exceptional temperature uniformity. This is the case during defrost cycles as well as normal operation. Now this type of freezer performance is available for facilities that prefer using 115 volt power outlets. Plasma freezers are available in both the i.Series® and Horizon Series™ lines. Sizes include undercounter models (4- and 5- cubic feet) and upright models (20- and 25- cubic feet).
The new 115 volt Plasma Freezers are part of the Helmer Scientific portfolio of medical-grade cold storage solutions. Click the button below for more information.
