Swivelock 5.5 and 4.75 drill bit, is it the same?
Yes, the spade drill bit (AR-1927D) is the same for both 4.75 and 5.5 mm swivelock. The internal diameter of the anchors are the same. The exterior thread diameter is larger and this is why they have their own tap (AR-1927CTB for 5.5mm and AR-2324PTB for 4.75mm).

Proper techniques for acquiring the blood:
Needle: 19-20G needle is recommended
Transferring from Syringe to IRAP II kit: When placing the pulled blood into the IRAP hold it at a 45 degree angle and put the blood in

Make sure that after the blood is pulled it is placed in the incubator within 1-1.5 hours and isn’t around extreme heat prior to incubation

Temperature: 37 degrees
Time: 20-22 hrs. (Anything over 24 hrs. incubation will not product serum)
Horizontal Incubation (red top down)
-Vertical incubation still okay, however you have a higher chance of the clot being in the way after centrifugations.

Spin with the white/clear side down. Allows the meniscus to be over the red side of the syringe. Clot will be furthest away from the clear tip

What Spin Speed do I use for IRAP II?
4,000 rpm
*Spin time is 10 minutes
Arthrex IRAP™ II – Autologous Blood Processing System

Issues with a Clot:
Clot is in the way of the serum?
4,000 rpm for 10 minutes and if a clot is still present you can try to re spin at 4,500 rpm for 10 minutes to get rid of/drop the clot

Individual doses may be used immediately or frozen at or less than -18°C for administration at a later date.

IRAP II Serum can be frozen for up to 12 months.

If the serum has been taken out of the freezer and thawed you could still put it back in the freezer to be refrozen if it’s been within 60 minutes.
