Product Description

A fractionating column or fractional column ,is a glass tube designed with many deep pointed intendations in its sidewall and two taper joints at both ends, used in laboratory fractional distillation in organic chemistry.This distillation column with vigreux belongs to air-cooled type condenser.Used in chemistry experiments involving fractional distillations or for separating two parts of a mixture based on their boiling points.

With 24/40 top outer and bottom inner joints.The lower joint usually fits a distillation flask with standard female joint,the upper joint connects a three way distillation adapter.

Laboy glass flasks are heavy wall designed,made by hand-blowing to ensure uniform wall thickness, made of high-quality borosilicate glass and annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.

US Standard Size Joint Will Fit into European Standard Size Joint

Standard Taper Ground Glass Joints are interchangable.For either frosted, presicon-ground standard taper joints (same size),the inner ground surfaces (male joint) make a good seal with the outer(female joint)). The joint size is described by the form A/B. The first number A represents the outer diameter (OD) in millimeters (mm) at the widest point of the inner (male) joint and the second number B represents the length of the joint. For example, a 14/20 joint is 14 mm wide at the top (the widest part) and is 20 mm in longth. The joint has a standard taper 1:10, any two joints (male and female) with the same outside diameter (A)can fit into each other ,no matther how lenght the joints are. For example, a 24/40 (US standard size) joint on a condenser will fit into a 24/29 (European standard size)flask but the ground glass joint will protrude (40 - 29) 11mm into the flask.
