1. Introduction

BXK16/26/50 lab-scale column is innovatively designed low pressure column. It is applicable in the processing of macro-biomolecules such as recombinant protein, antibody, vaccine and blood products, as well as R&D of micro-biomolecules such as antibiotics, peptide, synthetic drugs and other natural substances. The columns can be loaded by agarose-based, dextran-based and polymer-based resins including Bestdex,Bestarose,Chromdex. It can also be connected to chromatography systems(including AKTA). The product consists of high borosilicate glass inner tube, acrylic outer tube and POM plastic, which is suitable for most aqueous solutions via providing excellent bio-compatibility and chemical resistance.

Advantages of BXK 16/26/50 lab-scale column:

User-friendly, easy operation

Flared interface connector and highly elastic O-ring effectively prevent leakage

Evenly distributed outflow, promoting column efficiency after packing

Equipped with a thermostatic jacket for easy temperature control during the chromatography process
