CHROMABOND® flash safety system can be used as stand-alone system for any pump / detector / fraction collector combination with ¼"-28 fittings. Maximum safety up to 9 bar

CHROMABOND® safety holder, available in 5 diferent sizes (90, 180, 240, 360, 750/1000 ml)

• Universal connector
• Connects tubing from 0.15-0.53mmID
• Deactivated for maximum inertness

The new generation FactorFour columns have a guaranteed bleed specification, which is four times lower than any other column of similar selectivity available today. As a result, the traces can be determined with higher accuracy and detection limits, which are typically a factor two lower. Additionally, FactorFour reduces contamination of ion sources in mass spectrometer systems to a minimum.

Polymer standards are available in the widest range of molecular weights, and as kits and individual molecular weights for maximum choice.

Polymer standards are supplied with a comprehensive Certificate of Analysis detailing the characterization procedures employed and the results obtained.

These weights confirm to the Standard of the Organization Internationale de Metrologie Legale (OIML) International Recommendation R-111, France. They are manufactured of Stainless Steel with low magnetic permeability and high resistance to corrosion. All surfaces are polished to a perfect, mirror-like finish.
