Product features

Drying tube with one bulb is a glass tube with a thick upper part and a thin lower part. The upper diameter of the tube is round, which can be used to increase the mechanical strength. There is a bulb at the bottom of the thick tube for storing solid desiccant. A section of thin glass tube is welded to the lower end of the ball, which is used to fill the glass wool and insert the cork to fix it on the dry device.

Drying tube with one bulb is made of high-quality borosilicate glass, which has good chemical stability and corrosion resistance, ensures the accuracy of experimental results. With extremely high transparency, users can clearly observe the status of the desiccant in the tube, the flow of gas, and whether there are blockages etc other problems. Able to withstand certain high temperatures without deformation or damage, adapts to different experimental needs.The bulb part provides sufficient storage space for the desiccant. The gas fully interacts with the desiccant in the bulb, which can more effectively remove moisture or impurities and improve the drying and impurity removal effect. The thickness of the drying tube with one bulb is combined to filter and fix the desiccant, prevents the desiccant particles from flowing out with the gas.Good sealing is crucial to ensure the accuracy and safety of experiments. Different desiccants or impurity removers can be placed in different drying tubes to perform multi-stage treatment of the gas to obtain purer gas. It is easy and quick to operate and can quickly set up a gas drying or impurity removal system. Small size and light weight, easy to carry and store.

Drying tube with one bulb has low expansion rate, high temperature resistance, acid and alkali resistance, high strength, high hardness, high transmittance, high chemical stability, fine craftsmanship, smooth tube mouth, uniform wall thickness, no protrusions, no burrs. Good light quality, high transparency, strong and durable, exquisite tube, beautiful and practical.

Product applications

Drying tubes with one bulb are suitable for laboratories in schools, factories and enterprises. They can dry a small amount of gas, filter out impurities in the gas, or prevent materials in the device from absorbing moisture. Sometimes glass wool can be added to absorb acid mist etc. 

Gas drying: By placing appropriate desiccants in the bulb, such as calcium chloride, silica gel, molecular sieve, etc., the moisture in the gas can be effectively absorbed and the gas can be dried. It is suitable for various experiments and industrial production processes that require dry gas, such as chemical analysis, gas preparation, electronic industry, etc.

Gas impurity removal: According to different experimental needs, the corresponding impurity removal agent can be selected to be placed in the bulb to remove impurities in the gas. For example, in organic synthesis experiments, activated carbon can be used to remove organic impurities in gases; in certain experiments, specific chemical reagents can also be used to remove acidic or alkaline gas impurities.
