GC tools

Tools and general accessories for GC

Features

	Soap film flowmeters: primary standard for measuring gas flows, available in three different sizes leak check 734145 is the ideal residue-free solution to be used with these flowmeters

	Diamond file: a useful tool for cutting capillaries and smoothing ends of capillaries. Square capillary ends without protruding particles are especially important for butt connections (e. g. in Valco unions).

	Magnifying lens: a very versatile tool for any laboratory. In capillary GC it is often important to inspect column integrity or check cut ends of capillaries. When closing a column by melting the magnifying lens can be used to check whether the column is really closed or whether an open channel has been formed in the sealed end. Our lens provides 7fold magnification and is supplied with a scale as pictured in the figure below. The space between lines corresponds to 1/10 mm.

	Empty cages: are e. g. required for retention gaps and deactivated capillaries

	Glass wool, quartz wool, glass fibre wadding: are e. g. used for GC liners, packed GC columns etc.
