BD Microtainer® blood collection tubes are designed for ease of use, helping ensure that a quality capillary blood sample is collected. These wider-diameter tubes feature the BD Microgard™ closure, which has an integrated collection scoop and improved mixing ability. This full array of microcollection tubes is available for hematology and chemistry applications.
Microtainer tubes are equipped with two different closure types. The external dimensions of tubes with the BD Microgard™ closure are 15.35 mm X 46 mm. Microtainer tubes with FloTop collector closures measure 9.85 mm X 52.07 mm.
Microtainer tubes with gel should be spun at 6000-15000 relative centrifugal force (RCF) for 90 seconds and non-gel tubes at a minimum of 2000 RCF for 3 minutes.
