General Recommendations
3 .1
Intended Use
Helmer plasma thawing systems are intended for thawing frozen blood products and other medical,
biological, and scientific products.
3 .2
General Use
Allow plasma thawer to come to room temperature before switching power on.
During initial startup, low temperature alarm may sound while plasma thawer reaches operating temperature.
3 .3
Initial Loading
Allow chamber temperature to stabilize at the setpoint before thawing frozen product.
