Lense with scale, 8x

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 8fold magnification and is supplied with a scale. The space between lines corresponds to 1/10 mm. Glass wool, quartz wool, glass fiber wadding: are, e.g., used for GC liners, packed GC columns etc.
