Laboy Glass Fractional Distillaton Apparatus Kit Fractionating Distilling Set with 24/40 Joints & Vigreux Column Organic Chemistry Lab Glassware Equipment

Bullet:

Fractional Distillation is used to separate liquids with closer boiling points,with the fractional column, the vaporization and condensations take place repeatedly before the distillate is collected,the components of a mixture can be separated in a more efficient way.
This fractional distillation apparatus kit supplied by Laboy is similar to the simple distillation apparatus but with a vigreux column, which can be replaced by a packed distillation column as the fractional column.The column is placed between the distillation flask and the distilling head of the distillation apparatus and provides a large surface area over which a number of separate liquid-vapor equilibria can occur.
This distillation apparatus kit includes 1000mL,500mL round bottom flasks,250mm erlenmeyer flask as distillation and receiving flasks,liebig condenser,distillation column,3 way thermometer adapter, vacuum take off adapter,All the glassware are with 24/40 standard taper joints.
Laboy glassware are all made of high quality boroslicate glass according to ASTM E438,heavy wall design,durable and reusable.The ground joints are precisely grounded according to US standard.

Product Description:

Fractional distillation is used for mixtures containing chemicals with boiling points close to each other in order to separate the components by repeated vaporization-condensation cycles within a packed fractionating column.Similar to simple distillation but the process is repeated many times.In practise,placing a fractional column between the distillation flask and the distillation head in a simple distillation apparatus makes a fractional distillation apparatus.

Made of high quality borosilicate glass 3.3 having very low coefficients of thermal expansion for resistance to heat, and a very high resistance to chemical attack.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.
