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

Description RIVIERA Membrane Filters are ideal to serve the Industries which desire fine filtration. These Membrane Filters are used extensively for removal of particulate, bacteria and virus from liquids as well as from air. - Cellulose Nitrate Membrane Filter – Type RCN, RIVIERA Cellulose Nitrate Membrane Disc filters are hydrophilic, non-media migrating, biologically inert. Available in wide range of pore size from 0.22µm to 0.80µm - Cellulose Nitrate Membrane Filter – GRIDDED - Type RGCN, RIVIERA RGCN membranes are made of cellulose nitrate, a material which assures effective retention with high flow rates. These membranes are useful for water microbiology. A grid is printed on the surface to facilitate colonies. - Nylon-66 Membrane Filter – Type RN, RIVIERA Nylon membrane disc filter is double layered hydrophilic, non-media migrating, biologically inert, flexible, durable, plain white absolute membrane filter offering wide chemical compatibility - Edge Hydrophobic Membrane Disc Filter – Type REHCN, RIVIERA REHCN Membranes are used for sterility testing of antibiotics & drugs containing bacteriostats. 6 mm rim is hydrophobic and rest of the membrane is hydrophilic.
