GL Sciences is a well-known & major manufacturer of Sample Preparation products since years..
They produce Solid Phase Extraction columns & cartridges, SPE 96 well-plates, QuECHERS, ... under InertSep brand name.

The InertSep series is an original GL Sciences brand produced in their own factory through development, manufacturing, quality control and inspection. The Fukushima Manufacturing factory has obtained the International Organization for Standardization ISO-9001 certification. All solid-phase extraction products are manufactured under strict quality control and widely used in the analysis of food and water samples. All products are inspected and only those which pass our stringent criteria are shipped to customers. On request, GL Sciences can provide a customization service and custom-made multi-sorbent beds in a cartridge.
Each box is delivered with its own CoA

Sorbent type

GL Sciences delivers product under Silica and Polymer based materials with numbers of bonding modification to create various selectivites. This allow to answer all analytical challenges.

They are also providing sample preparation items based on a unique monolithic material

MonoSpin is a solid-phase extraction spin column that uses silica monoliths with uniform continuum pores. It effectively and rapidly extracts, isolates, purifies, and concentrates samples by centrifugation.

• Easy operation by centrifuge
• Speedy sample treatment with a superb through the poree
• Excellent reproducibility (S-type) even at 100 uL or fewer elution volumes.
