Lab Reagents: Smart Buffers and Reagents
Biological buffers for the life science laboratory need to meet a wide array of criteria. These include good stability, lack of toxicity, precision in pH, pKa between 6.0 and 8.0 (the region in which most biological reactions occur), minimal salt effects due to the ionic composition of the solution, free of enzymatic and hydrolytic activity and minimal participation in biological reactions.
Buffers for molecular biology applications, e.g. Tris-Borate-EDTA and Tris-Acetate-EDTA, need to be free from DNAse and RNAse activity. Medicago's SmartBuffers meet all these criteria. They are manufactured using highly purified, analytical grade chemicals and are extensively quality tested. Manufacturing is done in a controlled clean environment according to GMP procedures.
A high level of automation essentially avoids operator intervention and contact with the products.
SmartBuffers are supplied as exactly pre-weighed tablets packed in containers or blister packs or as exactly pre-weighed powder mixes packed in sealed aluminium foil pouches.

Description
Product description
Buffered Sodium Citrate is used in clinical laboratories and blood banks as an effective anti-coagulant, usually in a ratio of 1:9 sodium citrate/blood. The citrate ion chelates calcium ions in the blood by forming calcium citrate complexes and disrupting the blood clotting mechanism.
Medicago’s Buffered Sodium Citrate is supplied at two sizes with pouches giving 100 ml or 1000 ml of 3.2 %, 0.109 M buffered sodium citrate solution.

Notes
Directions for use
Empty one pouch of the powder in a laboratory flask or beaker placed on a magnetic stirrer. Add 50 ml or 300 ml of deionized water and stir the solution for a few minutes. Adjust the volume up to 100 or 1000 ml, stir and the solution is ready to use.
Shipping and storage
Buffered Sodium Citrate is shipped at room temperature. Store the pouches in a dry place at room temperature. Shelf life is three years after production date. Solutions can be stored at room temperature or at 4°C for two months.
