Supplier: Avantor

SPE sorbent for clean-up columns. Suitable for the determination of Hydrocarbon Oil Index according ISO 9377-2 and NEN 5733.

Supplier: G-Biosciences

These cross-linking agents contain at least two reactive groups that are reactive towards numerous groups, including sulphydryls, amines and carbohydrates, and create chemical covalent bonds between two or more molecules. Functional groups that can be targeted with cross-linking agents are primary amines, carboxyls, sulfhydryls, carbohydrates and carboxylic acids. Protein molecules have many of these functional groups and therefore proteins and peptides can be readily conjugated using cross-linking agents.

Supplier: MACHEREY-NAGEL

The high purity CHROMABOND® adsorbents can be used for a self-filling of SPE columns or further analytical applications.

Anhydrous sodium sulphate is the most common drying agent used to remove moisture from sample extracts. Activate by heating to 400 °C for four hours before use.

Supplier: Restek

Diatomaceous earth is used as a filter aid to improve extraction efficiency of densely packed soils, such as clays. By mixing the sample with diatomaceous earth, recoveries can be improved and excess moisture can be absorbed.

PL Cl-Trt-Cl supports peptide synthesis using the Fmoc approach. This resin can be used for the synthesis of a wide range of organic acids, and has also been used for the synthesis of amines, phenols and other alcohols.

Supplier: VARIAN

PL-Wang is a 4-alkoxybenzylalcohol functionalised polystyrene, prepared from copolymerised PL-CMS, for solid phase peptide synthesis using Fmoc protection strategies and is cleaved using ~ 95% TFA. Particularly useful for solid phase synthesis of small molecules which have a carboxylic acid functional group.
