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.

•Pre-mixed powder buffers or tablets with pre-set pH

•Analytical grade reagents

•Eliminates calculation, formulation and weighing errors

•Dissolve-and-go for greater convenience

•Stable at room temperature for at least 3 years

•Guaranteed reproducibility

Sodium chloride

odium chloride is widely used in many laboratory routines. Medicago’s Sodium Chloride reagent is exactly pre-weighed as tablets or as a powder. For greater convenience a blister pack with 10 tablets is also avaliable.

Description

Product description

Sodium chloride is widely used in many laboratory routines. Medicago’s Sodium Chloride reagent is exactly pre-weighed as tablets or as a powder. For greater convenience a blister pack with 10 tablets is also avaliable. The reagent is 99.99% pure and is supplied in three concentrations. Dissolving one tablet or the contents of one pouch yields a solution containing:

1. 0.9 % sodium chloride (isotonic)

2. 3 M sodium chloride (hypertonic)

3. 5 M sodium chloride (hypertonic)

Features

Prepared from pharmaceutical grade reagents
Choice of tablets or powder mix in pouches
Isotonic
Choice of three concentrations
Eliminates variables in laboratory work flow

Directions for use

Empty one pouch or deposit one tablet of the NaCl reagent in a laboratory flask or beaker placed on a magnetic stirrer. Add deionized water and stir the solution for a few minutes. Adjust the volume up to 100 ml, 200 ml or 1000 ml respectively , stir until full dissolution and the solution is ready to use.

Shipping and storage

NaCl reagent is shipped at room temperature. Store the tablets and pouches in a dry place at room temperature. Shelf life is three years after production date.
