Laboratory flasks are vessels (containers) which fall into the category of laboratory equipment known as glassware. Flasks come in a number of shapes and a wide range of sizes. Laboratory flask sizes are specified by the volume they can hold, typically in metric units such as milliliters or liters. Measuring flasks are made from borosilicate glass. They are available with or without socket, stopper or even screw caps.
Flasks can be used for making solutions or for holding, containing, collecting, or sometimes volumetrically measuring chemicals, samples, solutions, etc. for chemical reactions or other processes such as mixing, heating, cooling, dissolving, precipitation, boiling (as in distillation), or analysis.
The types offered by us include the following:
Erlenmeyer Conical Flask with plain neck
Erlenmeyer Conical Flask with stopper neck
Round Bottom flask single or with multi necks
Flat bottom flasks
Volumetric flask is a piece of laboratory glassware used in analytical chemistry for the preparation of solutions. It is made of Borosilicate glass and consists of a flat bottomed bulb with a long neck, usually fitted with a stopper. The stopper is made from a chemically resistant plastic such as polypropylene or glass stopper is also given. The neck has a single ring graduation mark and a label. The label shows the nominal volume, tolerance, calibration temperature, class, relevant manufacturing standard and logo. The Amber Glass Colored Flask are also provided for handling light sensitive compounds such as silver nitrate.
We provide volumetric flasks generally in two different standards. The higher standard flasks (Class A) are made with a more accurately placed graduation mark, and have a unique serial number. Where this is not required, a lower standard (Class B) is used for qualitative or educational work. Compiles with ISO: 1042
Flask Volumetric (Measuring) "JSGW" with interchangeable stopper polypropylene or glass, accuracy as per Class 'A'Catalog. No. 62
* 1 ml. and 2 ml. Volumetric Flasks are of Test Tube shape.Note: Above flasks are also available in Amber Color.
An Erlenmeyer flask, commonly known as a conical flask or E-flask, is a widely used type of laboratory flask which features a flat base, a conical body, and a cylindrical neck. The Erlenmeyer flask is usually marked on the side (graduated) to indicate the approximate volume of their contents, and has a spot of white enamel where it can be labeled with a pencil.
Manufactured from Borosilicate glass for highest resistance to chemical corrosion.
White enamel graduation and marking spot
Reinforced rims for extra strength and resistance to impact fracture.
Round-bottom flasks are types of flasks having spherical bottoms used as laboratory glassware, mostly for chemical or biochemical work (for heating purpose). Made from heat-resistant borosilicate glass. Two or three-necked flasks are common as well. Round bottom flasks come in many sizes, from 5 ml to 20 L, with the sizes usually inscribed on the glass. In pilot plants even larger flasks are encountered.
