HPLC Grade                                     

For over three decades, Bio-Lab Ltd, an ISO 9001 and ISO 14001 company, has been producing high purity solvents, reagents and formulations for LC applications. Careful selection of raw material, in-process control and final all glass distillation are perfectly documented ensuring a high quality of production, with lot-to-lot reproducibility.

In high performance liquid chromatography the intrinsic quality of the solvents is of the greatest significance. We have been optimizing our HPLC grades to match many LC applications, enabling you to determine which is the best grade for your specific need.
Gradient grade HPLC solvents are specified with the gradient elution tests for the highest peak and drift at critical wavelengths in order to demonstrate the peak-free baseline. This enables you to make a better evaluation of minor impurities assuring optimum sensitivity.

Bio-Lab HPLC solvents are lot-to-lot analyzed to meet the high quality specifications for HPLC separations. We control the low levels of peak impurities, residue, water, acidity and alkalinity, the high chemical purity and the UV transmittance; all of which are critical parameters for a successful HPLC application.
All our HPLC solvents are filtered through 0.2 μm membranes, insuring particle-free mobile phases, and are bottled under inert gas for improved shelf life.


 

HPLC - Supra gradient

Our highest quality for very demanding HPLC analysis (see also Ultra LC/MS grade). Our specifications guarantees:

•       Ultra-low fluorescent impurity levels

•       Outstanding high UV transmission

•       Minimum peak impurities in the gradient chromatogram

•       Very low drift

HPLC - S (gradient grade)

Our standard gradient quality.

HPLC - R (isocratic grade)

The regular quality, satisfactory for most standard isocratic and routine gradient work.

HPLC preparative

A basic alternative for preparative HPLC and LC work. This quality is available for most solvents
