Adapters

Beakers

GWSI Industrial offers a variety of Glass Beakers to fulfill the needs of your laboratory. All of our glass beakers are part of our proprietary LabGlass® line. This glassware is created by hand utilizing state-of-the-art manufacturing and calibration techniques. Our skilled technical artisans use only the highest quality low expansion borosilicate 3.3 glass while following manufacturing and calibration techniques in accordance with ISO, DIN, and ASTM standards. The result is glassware with high heat tolerance, chemical durability, and precise measuring capabilities.

Bottles

Our premium bottles use high-temperature-resistant GL-45 screw caps made of Polybutylene Teraphthalate (PBT) and a silicone/PTFE liner. These caps can withstand temperatures of up to 180°C (dry heat) and 121°C (steam sterilization).

Burettes

GWSI Burettes are made of heavy walled 3.3 borosilicate glass tubings, with precise bore sizes to provide highest accuracy even after repeated usage. The Class A Burettes are individually calibrated as per ISO standard and supplied with calibration certificate which can be easily downloaded from the website. The burettes stopcock best drop control during the titration process.

Columns

Generally used for purification of individual compounds from mixtures of compounds

Condensers

Laboratory glassware is essential for distillation, reflux and extraction. Lab condensers & extractors facilitate precise phase changes and solvent recovery. These instruments are engineered to rigorous standards, ensuring technical compatibility and high-purity separation in controlled chemical analysis and laboratory procedures.

Cylinders

A measuring cylinder is a cylindrical container marked with graduated measurements, allowing users to measure liquid volumes with precision. It is designed with a narrow shape to minimize errors and ensure accurate readings. These cylinders are commonly made from glass or plastic and often feature a spout for easy pouring. The graduation marks on the cylinder help users measure liquids accurately without spillage or wastage.

Dishes Glass

Distillation Appratus

Easy to use, safe to operate and designed for trouble free continues operation. Suitable for general laboratory use.

Extractors

Soxhlet extraction units are laboratory apparatus used for the extraction of soluble components from a solid material. The process involves repeatedly cycling solvent between the boiling flask and the extraction chamber, allowing for the efficient extraction of target compounds. It is widely used in food industries to determine fat content in various food products.

filter Funnels

Designed with a 60˚ bowl angle High thermal shock resistance and chemical resistance Generally used for filtering and decanting liquids of varied densities

Flask Boiling

Round bottom boiling flask • Made of high quality, chemical resistant borosilicate 3.3 glass • Mechanically strong with low temperature gradient • Uniform thick wall design ideal for heating • Reinforced rims ensures high impact strength • Complies with DIN ISO 1773 standard

Flask Conical

Compliance with IS:1381 Standards. Made from Borosilicate 3.3 Glass. Uniform wall thickness distribution makes these flasks ideal for heating. The conical form makes them suitable for mixing liquids. The easy-to-read scale and large labelling field facilitate easy marking

Pipette

Pipettes are among the most commonly used liquid handling tools in any scientific laboratory. Whether it’s routine volumetric transfers or specialised tasks like artificial insemination and milk testing, laboratory pipettes ensure accuracy, sterility, and speed. From schools to pharmaceutical QC labs, they are indispensable.

Separating Funnels

Funnels might look like a simple tool, but they are very important in the lab. Laboratory funnels are basic tools used in the pharmaceutical, analytical and industrial research fields. They are used for moving liquids and for phase separation.

Stoppers

Ensure airtight sealing for all your laboratory glassware with high-precision glass stoppers, crafted for durability and chemical resistance. Designed for laboratories that demand accuracy, our glass stoppers provide a perfect fit to prevent leaks and contamination.

Test Tubes and Vials

Test tubes and glass tubes are important things that are used in labs. People use them for reagent handling, sample digestion, and centrifugation, as well as more complicated analytical and biochemical processes. Selection of the test tube doesn't just depend on volume; it also depends on base shape, closure compatibility, wall strength, and how well the chemical is tolerated.

Volumetric Flask

Volumetric Flask represents a specific category of laboratory apparatus designed to measure liquid volumes with high precision. Volumetric flask calibrated to either contain or deliver exact quantities of liquid at specified temperatures, typically 20 °C or 27 °C, to suit both standard and tropical laboratory conditions. GWSI manufactures this glassware using 3.3 low-expansion borosilicate glass, ensuring adherence to strict dimensional tolerances and resistance to chemical attack.
