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.

•Guaranteed reproducibility


Ringer Solution Tablets

Ringer solution maintains the osmotic balance for bacteria. It is used for the preparation of suspension of samples and other biological matter in dilution techniques for enumeration. It is also used in the microbial control of apparatus by the rinse and swab method.Medicago’s Ringer solution is supplied as pre-weighed tablets in bottles. One tablet yields 500 ml of buffer solution in the composition:1 x solution; 2.25 g/L Sodium chloride, 0.105 g/L Potassium chloride, 0.12 g/L Calcium chloride and, 0.05 g/L Sodium bicarbonate.

Applications

  • Isotonic sample diluent
  • Rinse solution for microbial control, the rinse and swab method
  • Suspension of solid food and other specimens
  • Diluent for pure bacteria colonies

 

Directions for use

Dissolve one tablet in 500 ml of deionized water. Stir untilfull dissolution and sterilize by autoclaving at 121°C for 15 minutes if needed.

Shipping and storage

Ringer solution is shipped at room temperature. Store the tablets in a dry place at room temperature. Shelf life is three years.

Tips and hints

If the tablet is not properly dissolved, make sure:- the water temperature is 22-25°C- the buffer is properly stirred- high quality deionized water is used. Sterilization can be performed by filtration or autoclaving. Filter the buffer solution into a sterile flask through a 0.22 μm filter.
