VACUETTE® Coagulation Tubes and VACUETTE® CTAD Tubes
 

Coagulation tubes are filled with buffered tri-sodium citrate solution. Citrate concentrations of either 0.109 mol/l (3.2%) or 0.129 mol/l (3.8%) are available. The choice of the concentration depends upon the policies of the laboratories. The mixing ratio is 1 part citrate to 9 parts blood.

CTAD tubes contain besides the buffered citrate solution, theophylline, adenosine and dipyridamole. VACUETTE® Coagulation and CTAD tubes are used for coagulation tests. Click Here for more information

VACUETTE® Serum Tubes

Serum tubes are coated with micronised silica particles, which activate clotting when tubes are gently inverted.
Serum tubes with gel contain a barrier gel that is present in the bottom of the tube. The specific gravity of this material lies between the blood clot and the serum. During centrifugation the barrier gel moves upward to the serum - clot interface, where it forms a stable barrier separating the serum from fibrin and cells. Serum may be aspirated directly from the collection tube, eliminating the need for transfer to another container. This barrier allows for the stability of certain parameters in the primary tube under the recommended storage conditions for up to 48 hours.
Serum tubes with beads contain polystyrene beads, which are present in the bottom of the tube. The specific gravity of the beads lies between that of the blood clot and serum. During centrifugation the beads move upwards to form a layer between the serum and blood clot. Click Here for more information

VACUETTE® Heparin tubes

The interior of the tube wall is coated with lithium heparin, ammonium heparin or sodium heparin. The anticoagulant heparin activates antithrombins, thus blocking the coagulation cascade and producing a whole blood / plasma sample instead of clotted blood plus serum.
Plasma tubes with lithium heparin and gel contain a barrier gel in the tube. The specific gravity of this material lies between that of the blood cells and plasma. During centrifugation the gel barrier moves upwards providing a stable barrier separating the plasma from cells. Plasma may be aspirated directly from the collection tube, eliminating the need for manual transfer to another container. This barrier allows for the stability of certain parameters in the primary tube under the recommended storage conditions for up to 48 hours.
Lithium determinations should not be performed in VACUETTE® Lithium Heparin tubes. Ammonium determinations should not be performed in VACUETTE® Ammonium Heparin tubes. (Ammonium Heparin tubes are not available in U.S.A.) Click Here for more information

VACUETTE® EDTA tubes

The interior of the tube wall is coated with either EDTA K2 or EDTA K3. The tube is also available with an 8% liquid EDTA solution. The EDTA binds calcium ions thus blocking the coagulation cascade. VACUETTE® EDTA tubes can be used in direct sampling analysers without actually being opened. Erythrocytes, leucocytes and thrombocytes are stable in EDTA anticoagulated blood for up to 24 hours. Blood smearing should be done within 3 hours after blood collection. VACUETTE® EDTA tubes are used for testing whole blood in the clinical laboratory.
VACUETTE® EDTA K2 tubes are used for testing whole blood in molecular diagnostics. VACUETTE® EDTA K2/gel tubes are used for testing plasma in molecular diagnostics and viral load detection. HIV and HCV are stable for up to 72 hours in a non-centrifuged sample at room temperature (20–25°C). However centrifugation for VACUETTE® EDTA K2/gel tubes should be done within 6 hours after blood collection for best results. Mid- term storage (up to 2 weeks) in primary tubes is recommended at –20°C. For long-term storage (over 2 weeks) at –70°C or at lower temperatures please store aliquots in cryo vials.

VACUETTE® Glucose tubes

Glucose tubes are available with different additives. The tubes contain an anticoagulant and a stabilizer, i.e. EDTA and sodium fluoride / potassium oxalate and sodium fluoride / sodium heparin and sodium fluoride / lithium heparin and iodoacetate.
VACUETTE® glucose tubes are suitable for the analysis of blood sugar and lactate. Click Here for more information

VACUETTE® Crossmatch tubes

Crossmatch tubes are available in two different versions. One tube type contains clotting activator used to make crossmatch tests with serum, while the other type contains EDTA and is used to make crossmatch tests with whole blood. The field of application is crossmatching. Click Here for more information

VACUETTE® Blood Grouping tubes

Blood grouping tubes are available with ACD (Acid Citrat Dextrose) solutions in two formulations (ACD-A or ACD-B)  or  with CPDA solution (Citrate Phosphate Dextrose Adenin). VACUETTE® blood grouping tubes are used for blood grouping tests or cell preservation. Click Here for more information

VACUETTE® Trace Element tubes

Trace element tubes contain either sodium heparin or clot activator and are used to test trace elements such as Cu, Zn, Pb, etc. Click Here for more information

VACUETTE® ESR tubes

ESR tubes contain a 3.8% buffered tri-sodium citrate solution (0.129 mol/l). The mixing ratio is 1 part citrate solution to 4 parts blood. VACUETTE® ESR tubes are used for the collection and transport of venous blood for blood sedimentation rate testing. ESR measurements refer to the Westergren method. Click Here for more information
