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.

Related Products Laboy Glass 3 Way Distilling Connecting Adapter with 24/40 Joints for Distillation Apparatus A 3 way distilling adapter ,also called 3 way connecting adapter,distilling head,is designed with three joints: one female joint at top and two male joints at the sidearm and bottom.It is commonly used in the distillation apparatus for distillation,vacuum distillation.Similar to 3 way thermometer adapter HMA016103. In the distillation apparatus ,the top female joint is designed to hold a thermometer adapter accommodating thermometer to monitor the vapor temperature during distillation,the male joint at sidearm used to connect a distillation condenser(liebig,coiled).The male joint at bottom to connect a distillation flask(round bottom flask) or a distillation column(vigreux column or hemple column) This distillation adapter is with 24/40 standard female taper joint at top,and one 24/40 male joint at side arm and one 24/40 male joint at bottom. Laboy Glass 3 Way Distilling Thermometer Adapter with 24/40 Joints The 3 way distilling thermometer adapter has a compression cap to form a vacuum tight seal of plain thermometer on Top. With 24/40 two inner joints at bottom and side,and the two joints are at a angle of 75 Degree .The bottom joint is usually connected to a distilling column for fractionation distillation or a distilling flask for the steam or vacuum distillation.The side joint may connect to a liebig or west condenser for water in and out when the temperature below 150 degree C,connect a air condenser if temperature above 150 degree C. The compression cap and o-ring fitting the thread opening at the top of the adapter, accommodating a thermometer or bleeding tube. Laboy Glass 500mL Single Neck Round Bottom Boiling Flask Heavy Wall 24/40 Joint Heating Distillation Reaction Receiving Flask Round-bottom flasks (also called round-bottomed flasks, Flasks, round bottom, or RB Flasks)having spherical bottoms are more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface. Because of the spherical bottom, cork rings are needed to keep the round bottom flasks upright,or heated by the water bath ,oil bath or sand bath.When in use, round-bottom flasks are commonly held at the neck by flask clamps on a stand. The flasks are usually used in heating or boiling a liquid, in distillation as distilling flasks and receiving flasks for the distillate, used as the distilling flasks in rotary evaporators.It is usually used with other jointed lab glassware like glass condenser,separatory funnels,cow receivers. The round bottom flask has larger heating surface than the flat bottom flask and can be heated evenly.It is usually used in the laboratory operation requiring high temperature and long time heating,or vacuum distillation. LBFD001 Laboy Glass Fractional Distillaton Apparatus Kit Fractionating Distilling Set with 24/40 Joints & Vigreux Column 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. 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.
