Greiner Bio-One VACUETTE Tube 3.5 ml Clot Activator Serum Separator Coated Additive Non-Rinse Red/Yellow 13 x 75 United States

Description

VACUETTE™ CAT Serum Separator Clot Activator tubes are evacuated blood collection tubes used for serum determinations. They contain clot-activating micronized silica particles and a gel separator that, once centrifuged, forms a stable barrier separating the serum from fibrin and cells.

• VACUETTE™ Blood Collection Tubes are evacuated for easy, safe sample collection. The amount of vacuum in each tube corresponds to the tube’s blood volume specification and helps ensure the correct blood-to-additive ratio.
• Injection molded from polyethylene terephthalate (PET) plastic, VACUETTE™ Blood Collection Tubes are highly transparent and virtually unbreakable.
• VACUETTE™ Serum tubes include a clot-activating additive – micronized silica particles – that is spray-dried on the interior tube wall for even disbursement and optimal blood/additive mixing.
• Serum tubes with gel contain a barrier gel to separate the serum from the fibrin and cells. During centrifugation, the barrier gel moves upward to the serum/clot interface, where it forms a stable barrier. This barrier separates the serum from fibrin and cells.
• Optimal fill marks on every tube label indicate the proper draw volume for correct blood-to-additive ratios (within ±10% of the stated nominal volume in accordance with ISO and CLSI).
• Featuring red VACUETTE™ SAFETY Caps, designed to minimize the spraying of aerosols during decapping and color-coded to aid first-glance tube recognition.
• Sterile and latex-free.
