Our Products

Adapters listed here are the most widely used ones and will permit a laboratory to assemble.Their own apparatus using the flasks and condensers listed herein. The joints are fully interchangeable and made to the same precision as all BOROSIL® ground joints.
Adapters
VIEW DETAILS
Blood sugar, Digestion and Centrifuge - We offer an assortment of centrifuge tubes and Folin-Wu Tubes. All are made from uniformly drawn high quality tubing for extended service life and graduations, where provided, are in durable white enamel.
Tubes
VIEW DETAILS
Test tubes and culture tubes are made from machine drawn, uniform thickness, low expansion borosilicate glass tubing. The bottoms of these are with uniform thickness to withstand both mechanical and thermal shocks. The rims wherever provided, are strong. Test-tubes without rim (Culture tubes) have heavy fire-polished ends which are resistant to mechanical shocks of daily use. Culture tubes are good for cell growth. The caps and washers provided on Screw cap Culture tubes withstand repeated autoclaving.
Tubes Test & Culture
VIEW DETAILS
Borosil Fused Silica 99.95% SiO2 surpasses all of the desirable chemical and weathering durability properties usually associated with opaque Silica ware. We manufacture as per IS and BS Stand-ards.a) There is little or no visible surface change or damage to silica with prolonged exposure to water, atmospheric gases, contaminants, oxide of nitrogen and ozone.b) Attack does occur, on exposure to alkaline solution and acids at very high temperatures.c) Low expansion and hence excellent dimensional stability and thermal shock resistance.Resistant to chemical attack. Virtually unaffected by sulphuric, nitric and hydrochloric acids. Hot alkalies and certain metal oxides react on silica. It is attacked by hydrofluoric acid. At high temperatures, it is also attacked by phosphoric acid. Continuous use of fused silica above 10000C leads to devitrification with formation of crystobalite which is a crystalline phase and will lead to breakage on repeated use. For accurate and long use, it is advisable to wash the articles in distilled water and alcohol to remove trace impurities. Heating fused quartz to elevated temperatures causes Si02 to undergo dissociation. Consequently, when flame-working fused quartz, there is a brand of haze or smoke which forms just outside the intensely heated region. This haze presumably forms because the Si02 recombines with oxygen from the air (and perhaps water) and condenses as extremely small particles of amorphous Si02.
Quartz Ware

These Watch glasses possess high chemical durability thus preventing contamination of solution. They are moulded to the same radius of curvature for convenient stacking. The heavy wall and uniform fire polished edges provide mechanical strength.
