Plasma Freezers

Our extensive range of plasma freezers from Haier Biomedical and KW Apparecchi Scientifici operate between -20°C to -40°C.

Their versatility means they can also be used in laboratories to store samples as well as fresh frozen plasma (FFP).

Various sizes are available, from countertop, under bench, to single and double door free standing units. Twin refrigeration systems on some models offer added peace of mind.

Frequently Asked Questions

How long can fresh frozen plasma be stored in a plasma freezer?

Fresh frozen plasma (FFP) is the liquid part of blood that can be extracted from donated blood. It is kept frozen so it can be stored safely and used later in patients who:

Have lost a large quantity of blood – plasma transfusion can replace the fluid lost.
Don’t have enough clotting factors in their blood because of conditions such as haemophilia and can’t stop bleeding.
Lose a lot of blood while taking blood thinners (these prevent blood clots – plasma transfusion adds necessary fluids and clotting factors to stop bleeding.)

To keep FFP stable and viable it must be stored at − 18°C or colder to give it a shelf life of 12 months.

To extend the period of viability to 7 years, FFP should be kept at − 65°C.

Once requested for patient blood transfusion, FFP is thawed in a dry plasma thawer at around 37°C for 15 minutes before being given to the patient.

How to prepare FFP for storage in a plasma freezer?

Plasma makes up the largest proportion of blood, around 55% of total blood volume and is made up of water, lipids, salts, and hormones.

Plasma is separated from whole blood using centrifugation, which forces the denser, heavier particles to the outer edges of the sample. This creates three layers of differing densities, including red blood cells, white blood cells and platelets, then the plasma. This allows for plasma to be removed and frozen, to make it last longer.

FFP bags are generally stored upright once frozen, either in baskets or directly on the freezer shelves – however, if you would prefer to store them horizontally you can, it doesn’t affect the quality of the FFP inside.

For more information about how to keep your FFP in the best condition for future transfusion, contact us today here at QED Scientific. You can fill in our online contact form or give us a call on 01663 735 494.

Do plasma freezers have any safeguarding features?

To ensure FFP is safe for use for all patients, plasma freezers use a selection of safeguarding features which alert laboratory staff to changes or malfunctions within the freezer.

These features, understandably, are considered essential for most laboratories.

Here at QED Scientific, our range of plasma freezers include safety features such as:

Accurate digital temperature controls – to allow for precise temperature setting.
Lockable doors – remove the chance of a freezer door hanging ajar ever again.
Minimum and maximum temperature memory – which provides peace of mind for laboratory staff as they can check the historic temperature of the freezer.
Multiple alarms – including temperature, door and mains fail alarms.
