Description Connection System with screw cap and 2 or 3 GL 14 ports, PP, blue/grey Manufactured from Polypropylene Rigid or semi-rigid tubing of different diameters can be accepted by using a blue GL 14 open topped cap with one of the inserts. Available with 2, or 3 threaded outlets (ports). Four different tubing diameters (1.6 mm, 3.0 mm, 3.2 mm or 6.0 mm tubing outer diameter) can be used by changing the GL 14 inserts. By applying positive or negative pressure liquid can be pumped out of or into the bottle via the screw cap. Fully compatible with all the GL 45 threads and therefore highly versatile.

Description Vitreous Silica is the glassing modification of silcon dioxide with a purity of 99.9% in the transparent form and is called fused silica. All our silica ware products are made out of fused silica. Fused silica is completely unaffected by acids such as sulpuric, nitric and hydrochloric, however, it can be affected by hdrofluric acid and at high temperatures also by phosphoric acid. Hot alkalies and certain metallic oxides also react on fused silica. Fused silica is boron free They are of very low expansion and hence have excellent dimensional stability and thermal shock resistance Technical Specifications: - Electrical resistivity - (at 350°C) 7 x 107 ohm cm - Average co-efficient of expansion - 5.5 x 10-7 / °C - Softening point - 1685° C - Annealing point - 1200° C - Operating temperature (continuous) - 1050° C - Operating temperature (intermittent) - 1350° C Working temperature - 1950° C Strain point - 1120° C
