High performance liquid chromatography (HPLC) is a biochemical analysis method used to separate, identify and quantify substances in a mixture. Compared to simple column chromatography, HPLC separates the mixture of substances under pressure and possibly also under the influence of temperature with the help of two phases, a stationary and a mobile phase, faster and more precisely.
The mobile phase consists of solvents that are withdrawn from storage bottles. For reliable results without contamination from the environment on the one hand and to protect the user from solvent vapors on the other hand, it is necessary for these bottles to be equipped with special safety caps.
witeg offers a cost-effective solution for this: the complete safety system suitable for all GL 45 laboratory bottles and more.
