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.

Borosil brand volumetric flasks are built with your requirements in mind. They confirm to tight capacity tolerances and assure accurate reproducible results. The flasks have built in strength too. The flask body is specially blown and accurate bore tubing is used for the neck. And above all, you have interchangeable stoppers for convenience. In capacities from 1ml to 2000 ml, Borosil brand volumetric flasks are available in Class A accuracy, certified by us and Class B accuracy, for general purpose work.

When you use a burette you expect accuracy, reliability and durability. Only Borosil brand burettes offer all three even after repeated usage. A combination of the best material and workmanship goes into Borosil brand burettes. The highest quality accurate-bore tubing is selected to provide uniform and accurate graduations. Each burette is individually calibrated for precision and high accuracy. All graduations are in durable white enamel. The burette stopcocks are specially ground so that they provide a leak proof operation. It is advantageous to use different types of greases depending on the reagents used to get leak proof operations. Stop-cock plugs are solid pressed and ground. These are not interchangeable. In addition to Burettes with glass stop-cocks we have burettes with straight bore PTFE stopcocks and a range of Boroflo Burettes fitted with Boroflo(GP) screw thread stop-cocks with PTFE Keys. Boroflo Burettes are fitted with Boroflo GP(General Purpose) Screw thread Stopcocks with PTFE keys offering the following operational advantages -

Large deep spacing between wells to prevent cross contamination in case of spills. The deep spacing extends to the outer edge of the outer rows of walls on all sides of the plate. Crystal polystyrene used for medical applications, high clarity and toughness, high light transferability with minimum light distortion

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.

It has established a 150 ton per day low iron patterned glass furnace for the manufacture of high transmission glass used in the solar industry.

Liquid Solid Extraction involves the elution of a solid sample with pure solvent vapour. The sample is held in the extractor body either directly or in a thimble. The siphoning type of Soxhlet Extractor finds the widest application in laboratory work. BOROSIL® Brand Soxhlet Extraction Apparatus are available in three sizes. The Component parts of the apparatus are provided with interchangeable joints for added flexibility.

This glass is used for multi and mono crystalline solar photovoltaic modules. The content of iron oxide is significantly lower than in normal flat glass, which gives it a distinctive, nearly colourless appearance particularly when seen from the edge, and makes it a high solar energy transmitting glass. The textured surface helps to diffuse the light and inhibits the reflection of a part of the solar energy back into the atmosphere as compared to a polished surface, thus enhancing solar energy transmission. We manufacture two kinds of textured glass: prismaticmatt and mattmatt as per the customer's requirement. Our manufacturing and processing plants are accredited with ISO 9002 certification. The finished products conform to the standards of various national and international testing and statutory agencies. Our packing is widely recognized and acknowledged as one of the best in the industry.

TECHNICAL DATA Borosil Brand sintered glassware is used for the filtration of liquids and gases in the laboratory. It incorporates a porous glass disc as a filter media, which is non corrosive and reusable. It is also used for gas washing, dispersion and absorption. Sintered disc is manufactured by crushing Borosil brand glass, powdering, cleaning, separating into various mesh sizes and then fusing together in the form of a disc. The sintered disc is graded into 5 grades -G1, G2, G3, G4 and G5. The grades are classified by maximum pore size, which is obtained by measuring pressure at which the first air bubble breaks away from filter under certain conditions. The pressure differential is then used to calculate the equivalent capillary diameters in microns. The desired pore size is obtained by suitably controlling the grain size, firing time, temperature and the thickness of the disc. Each disc is tested and graded individually. The pore diameters are reasonably uniform, which ensures required flow rate through the filter. The flow rate further depends on pressure differential between the two sides of the disc, free area of the disc, viscosity of the fluid being filtered, etc. Between different discs of same size and grade, there is a fair amount of uniformity in pore size and hence the results from two or more discs of the same size and grade will be uniform. This ensures reproducible analytical results. The discs have maximum surface hardness and hence glass powder does not get scraped off during cleaning or with chemicals. Filters do not shed particles during usage. The discs are sealed to tubing without blocking the pores. Then they are annealed properly in automatically controlled lehrs.

Along with micropipettes, Borosil introduces stands. These stands are available in several designs both for single channel and multichannel. Attractively designed, these stands are presented in various types to suit every requirement and application.
