Product features

Receiving tube 105° with standard ground mouth is a glass instrument accessory used in chemical experiments. It is usually used in experimental devices such as distillation and fractionation to connect the condenser and the receiving bottle. The main body of the receiving tube is made of glass, usually made of high borosilicate glass, which has good chemical stability, heat resistance and transparency. It has a 105° bending angle, which allows it to maintain a suitable inclination when connected to other instruments, facilitating the smooth flow of liquid into the receiving bottle while avoiding liquid reflux or splashing. The ground mouth part adopts a standard ground mouth design, and common specifications include 14/20, 19/22, 24/29, 29/32, etc.This standard ground mouth can be tightly connected with condensers, distillation flasks, receiving bottles and other instruments of the same specifications to ensure the sealing of the device and reduce the risk of leakage during the experiment. The 105° standard ground mouth of the receiving tube is mainly used to guide the condensed liquid from the condenser to the receiving bottle.

Receiving tube is usually made of high borosilicate glass and other materials, which has the characteristics of high transparency, high temperature resistance, corrosion resistance and high transparency. Very low thermal expansion coefficient, about one-third that of ordinary glass. The frosting is fine, the seal is leak-proof; the surface is smooth, beautiful and elegant; the pipe is thickened, with excellent craftsmanship and firm welding.

Product applications

(1) Distillation experiment: used to connect the condenser and the receiving bottle, collect fractions with different boiling points, and achieve separation and purification of the mixture.

(2) Fractionation experiment: During the fractionation process, with the help of instruments such as the fractionation column, the mixture with similar boiling points is gradually separated, and the receiving tube is used to collect different fractions.

(3) Vacuum distillation: by vacuuming the system pressure to reduce the liquid boiling at a lower temperature, the receiving tube collects the distillation product under reduced pressure to avoid the decomposition or deterioration of the substance at high temperature.

(4) Other chemical experiments that require precise collection of liquid products: such as in the post-processing process of organic synthesis reactions, it is used to collect the liquid products generated by the reaction for subsequent analysis and purification.
