Vacutainer® Citrate Tubes with 3.2% buffered sodium citrate solution are used for routine coagulation studies. Venipuncture sampling system which enables sampling directly into a sterile tube One-handed manipulation permits fixing the vein with the free hand System composed of…

Contains buffered tri-sodium citrate solution Color-coded rings in caps indicate draw volume Citrate concentrations of either 3.2% (0.109M) or 3.8% (0.129M) are available, with a mixing ratio of one part citrate to nine parts blood. Sold by: 1000 Per Case; Contains: Buffered Sodium Citrate (0.109M, 3.2%). Optional: Theophylline, Adenosine, Dipyridamole (0.3 mL) Color: Light Blue PT Tube (Sodium Citrate 3.2%)is mainly used for the test of blood coagulation mechanism. It is filled with buffered tri-sodium citrate solution, and citrate concentrations of either 0.109 mol/I (3.2%) or 0.129mo1/(3.8%) are available. The choice of the concentration depends upon the policies of the laboratories. This light blue top sodium citrate tube, or Coagulation Tube, is used for examination of coagulation parameters. Coagulation tubes contain a buffered sodium citrate solution. It is available with a citrate concentration of 0.109 mol/l (3.2%) or 0.129 mol/l (3.8%). The mixing ratio is: 1 part citrate solution to 9 parts blood. BD Vacutainer® Citrate Tubes with 3.2% buffered sodium citrate solution are used for routine coagulation studies. ClosureType/Color: BD Hemogard/ Light Blue Additive/Concentration: Buffered Sodium Citrate (0.109M, 3.2%) Sodium citrate (0.102 M, 0.129 M citrate, buffered and nonbuffered) at a ratio of nine parts blood to one part anticoagulant is the anticoagulant typically chosen for platelet aggregation testing. Laboratories involved in aggregation testing do not use Vacutainers to obtain blood due to the concern that the platelets may become activated by the Citrate Buffer (pH 3.0 to 6.2) preparation guide and recipe. Recipe can be automatically scaled by entering desired final volume. Citrate buffers can be used for RNA isolation, due to its ability to prevent base hydrolysis. The buffer is also used for antigen detection by breaking cross-links between antigens and any substances in its fixation

The Effect of 3.2% and 3.8% Sodium Citrate on Specialized

Citrate for coagulation Made of clear polypropylene, supplied capped and labeled. Our sodium citrate, 3.8% or 3.2% concentration, buffered and sterile has a ratio citrate: blood 1:9 and is highly recommended for coagulation tests. Buffered to pH.

Simple Steps for Making Sodium Citrate Buffer

PT (Sodium Citrate 3.2 %) Tube, सोडियम साइट्रेट ट्यूब in PT Tube (Sodium Citrate 3.2%)is mainly used for the test of blood coagulation mechanism. It is filled with buffered tri-sodium citrate solution, and citrate concentrations of either 0.109 mol/I (3.2%) or 0.129mo1/(3.8%) are available. The choice of the concentration depends upon the policies of … The Effect of 3.2% and 3.8% Sodium Citrate on Specialized The 3.2% buffered sodium citrate binds less assay-added calcium than 3.8% buffered sodium citrate, therefore clotting times tend to be shorter in 3.2% than 3.8% buffered sodium citrate.1 Although there are no exact data available, today 3.2% buffered citrate is rather widely used. A survey conducted in 2001 revealed that 156 of 593 US hospitals Citric Buffer Calculation (JavaScript) Sodium Citrate = [Cit 3-] + (2/3)[HCit 2-] + (1/3)[H 2 Cit-] Using the molecular weights for anhydrous citric acid and sodium citrate dihydrate (the typical lab forms) together with the buffer strength, the actual percentages are calculated. The pK's used for citric acid are 3.15, 4.50 and 5.75.
