Product features

Connection tube with three standard ground mouths has three standard ground The standard ground three-mouth connecting tube is a common chemical experimental glass instrument, mainly used to connect different glass instruments to build complex experimental devices. It is usually made of glass, in the shape of a mountain, with three standard ground mouths, usually with a larger middle mouth and two relatively small and symmetrically distributed side mouths. There is a standard ground stopper at the bottom, which is used to install on a single-mouth flask to convert the single-mouth flask into a three-mouth flask, thereby meeting the requirements of performing multiple operations simultaneously in the experiment.There are many common specifications, and the sizes of the grinding mouths of different specifications are different. For example, in the 29x4 specification, the middle grinding mouth, the branch grinding mouth and the lower grinding plug are all 29/32; in the 24x3,29 specification, the middle grinding mouth and the branch grinding mouth are 24/29, and the lower grinding plug is 29/32, etc. Through the standard grinding mouth, it is tightly connected with other glass instruments, and the high-precision matching between the grinding mouths is used to achieve a sealed connection between the instruments, prevent gas or liquid leakage during the experiment, and ensure the accuracy and safety of the experiment. It has the advantages of good sealing and strong versatility.

Connection tube with three standard ground mouths has a smooth surface, no bulges, thickened glass, strong and durable, and high transparency. A variety of specifications, choose at will, clearly marked, easy to observe, and finely frosted. Welding is firm,it is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. It can be welded at 1100℃ and annealed at 600℃.

Product applications

Connection tube with three standard ground mouths is mainly used in the construction of chemical experimental equipment. It can transform a single-mouth flask into a three-mouth flask, which is convenient for performing multiple operations at the same time, such as installing a stirrer at the middle mouth, installing a distillation head at the branch mouth for separating substances, installing a separating funnel for adding reagents or extraction, and installing a condenser for reflux, etc., to meet the needs of different experiments such as synthetic reactions, distillation, and fractionation.
