Beakers

BOROSIL® Glasswares are best-in-class products with several advantages. They have a high level of thermal shock resistance and a high operating temperature. Besides using USP type I borosilicate glass constant quality control checks are conducted throughout the production process to ensure uniformity of the wall thickness. Such uniform wall thickness distribution prevents uneven expansion and stressing of the glass that often results in a failure.

BOROSIL® brand low form Beaker (Cat No. 1000) and BOROSIL® brand Tall Form Beaker (Cat No. 1060 ) are two popular styles used for storage and mixing.

BOROSIL® offers full range of beakers to suit every application.

Burettes

Accuracy, reliability and durability are the essentials of a Burette. Only Borosil branded Burettes offer you these three benefits even after repeated usage, as they are made with a combination of the best material and workmanship. The highest quality accurate bore tubing is selected to provide uniform and accurate graduations. Each burette is individually calibrated on a fully automatic machine for precision and high accuracy. All graduations are marked in durable white enamel. The stopcock plugs are not interchangeable.In addition to Burettes with glass stopcocks, Borosil offers Burettes with straight bore PTFE stopcocks and a range of Boroflo Burettes fitted with Boroflo (GP) screw thread stopcocks with PTFE keys. Borosil offers Class A Burette for accurate work

Cylinders

Measuring cylinders serve simultaneously to receive and measure different amounts of liquids. Made from specially drawn 3.3 Borosilicate glass tubing with durable, easy to read graduations for assured accuracy. Borosil Brand Cylinders are built to last long. We have built strength features into every cylinder. Heavy uniform wall tubing and strong stable hexagonal base contribute to sturdiness. Hexagonal base also prevents them from rolling off a laboratory bench. They are available in capacities from 5 ml to 2000 ml. For accurate work, Class A certified cylinders are available. Our range also includes Nessler Colour Comparison and Rain Measure Cylinders.

Filteration products

BOROSIL brand Flasks are designed to deliver the best combination of thermal shock resistance, physical strength and resistance to chemical attack. They are made so as to withstand the demands of the modern laboratory. Flasks with interchangeable joints are particularly suitable for all glass apparatus assemblies. Borosil offers the interchangeable joints most commonly specified for a particular capacity. Tube Adaptors Category Nos. 8800 and 8820 can be used to connect the Flask with a particular size joint to any other apparatus having a different size joint. Borosil offers a wide range of Flasks for a variety of applications such as boiling, culture, distilling, Erlenmeyer, Filtering, Iodine and Kjeldahl.

Round bottom flask

Whether it is research, industry or education, the Beaker has a wide range of applications. This simple container, used for stirring and mixing liquids, is also ideal for heating them. Controlled wall thickness at the sides, radius and the base, ensures a fine balance between the thermal resistance and mechanical strength, to enable effective heating. Many beakers also have a spout and that makes pouring easier and more precise. BOROSIL® Glasswares are best-in-class products with several advantages. They have a high level of thermal shock resistance and a high operating temperature. Besides using USP type I borosilicate glass constant quality control checks are conducted throughout the production process to ensure uniformity of the wall thickness. Such uniform wall thickness distribution prevents uneven expansion and stressing of the glass that often results in a failure.

Beakers are mainly used as heating vessels. The tall-shape design of the Beaker is ideal for heating in a liquid bath, especially when the contents need to be kept distinctly apart from the surrounding medium materials. BOROSIL® brand low form Beaker (Cat No. 1000) andBOROSIL® brand Tall Form Beaker (Cat No. 1060 ) are two popular styles used for storage and mixing. BOROSIL® offers full range of beakers to suit every application.

Funnels

Funnels may be used for separating solids from liquids, liquids from liquids and occasionally, for pouring something into a container.BOROSIL brand Funnels are available in a comprehensive range for a variety of such applications. Sintered Glass Funnels are also available.Separating Funnels come in globe, pear and cylindrical shapes with ground glass stopcocks and interchangeable stoppers. These Funnels are made of specially moulded blanks. Stopcock bores, body openings and stems are carefully aligned to facilitate the smooth and even flow of liquid with fast cut-off.

Reagent Bottles

Bottles have multiple uses, as Aspirator, Reagent and Solution Bottles. They are designed with heavier wall thickness, making them mechanically stronger to withstand wet or dry sterilisation. The high chemical durability of the glass ensures that most of the reagents can be stored in these bottles for long durations in almost the same condition. Plain Neck Solution Bottles are designed to have a uniform rubber stopper fit. Roux Bottles have flat surfaces and are widely used for culture growth. The outstanding BOROSIL quality provides capabilities for a wider range of functions, from long-term storage to the most demanding applications in the pharmaceutical industry.

All Borosil Pipettes are colour-coded at the top in accordance with ISO Standards, to facilitate easy identification. The graduation marks are screen printed. The mouth piece of Pipettes of 5 ml and above are tooled with uniform OD for easy sucking. Such tooling also imparts additional strength. BOROSIL Borosil brand Pipettes are truly dependable in terms of their accuracy. They are available in Class A certification.

Volumetric flask

Volumetric Flasks are manufactured in a range of sizes that are capable of containing 1 to 5,000 ml of liquid. It is very important to understand that for analysis that demands high precision and only high accuracy instruments give the desired results. Most sophisticated automatic instruments can deliver high precision results, only if the volumetric ware used to prepare samples is accurate. Borosil volumetric flasks are designed to give the best combination of thermal shock resistance, physical strength and resistance to chemical attack. They are made to withstand the demands of the modern laboratory and are particularly suitable for all glass apparatus assemblies. Calibration: Every Volumetric Flask is calibrated on fully automatic computer controlled calibration machine, eliminating the manual error in reading the meniscus, thereby giving more accurate volume

BOROSIL Class A Volumetric Flasks are available with Individual Calibration certificate.
