Equipment in the Component Manufacturing Laboratory Flashcards
very crucial (speed and duration), can spin 6 to 12 units
Centrifuge
typically either large floor units or large table top units that can spin a maximum of 6 to 12 units of whole blood at once.
Centrifuge
Purpose of centrifuge:
Separate red blood cells from plasma and other components
Centrifugation depends on the following conditions:
- Length/duration
- Speed
Recommended Centrifuge Conditions
AABB
- Red blood cells + plasma
- Soft spin
5000 x g = 5 minutes
Red blood cells + PRP
2000 x g = 3 minutes
- Harvesting platelets or cryoprecipitate from plasma
- Hard spin
5000 x g = 7 minutes
platelets that are not entirely removed from the plasma
PRP
Methods of Centrifugation
- Intermittent Flow Centrifugation (IFC)
- Continuous Flow Centrifugation (CFC)
- Blood is processed in BATCHES or CYCLES, hence the term intermittent
- Whole blood is drawn from an individual with the ASSISTANCE of a PUMP
Intermittent Flow Centrifugation (IFC)
In IFC, To keep the blood from clotting, an ___ is mixed with the ____ as it is pumped into a centrifuge _____ through the inlet port
anticoagulant
blood
bowl or chamber
- the processes of blood withdrawal, processing, and reinfusion are performed SIMULTANEOUSLY in an ongoing manner
- COMPLETE a cycle before beginning the next one
Continuous Flow Centrifugation (CFC)
In CFC, blood is DRAWN and RETURNED continuously during a procedure, ____ venipuncture sites are necessary
two
Plasma products that are REMOVED/SEPARATED from the red blood cell
Plasma Expressors
