BD Vacutainer® SST II Advance tubes are used to obtain and separate a serum sample. Tubes contain silica to activate clotting of the specimen, and a gel that forms a barrier between the clot and the serum after centrifugation. BD SST II Advance tubes contain an acrylic based gel and unique gel design with optimised slope. This design enables centrifugation flexibility which provides increased laboratory workflow and process efficiency. The minimum recommended clotting time for patients without anticoagulant is 30 minutes.
