The sealing of the mouth and cap of the wide mouthed reagent bottle is good, without the need for a cork, and it is also non permeable; Wide mouth design, easy to use, smooth inner and outer walls, easy to clean, and there is no liquid residue on the inne...

A test tube box, including a box cover and a box body, is characterized in that there is a test tube fixing device between the panel and the box body, a test tube opening is set on one side of the upper open box body, a cover is set at the test tube openi...

A dropper is a type of tube used to aspirate reagents, which uses plastic as the raw material. The dropper is widely used in the experimental process, and its function is to aspirate a small amount of liquid into other containers....

A reagent bottle is a bottle for storing reagents, which can be made of two materials: glass and plastic. The reagent bottle is not heat-resistant and has a ground mouthed dropper at the bottle mouth, which is called a dropper bottle. Reagents are require...

The pressure inside the dropper is lower than atmospheric pressure, and the dropper is subjected to a downward force from the atmosphere. The solution is simple: heat the dropper in a water bath (not directly) to increase the vapor pressure inside the dro...

Drip bottles are a common type of container in the laboratory, widely used due to their simple control of reagent usage. Drip bottles are also divided into many types, including transparent ones and dark brown ones. So what are the differences between the...

Requirements for the quality of reagent bottles: HF solution cannot be placed in glass bottles due to corrosion of the glass. Plastic bottles or lead containers can be used instead. Other reagents are generally stored in glass bottles....

Straw making method: After melting the plastic, it is passed through an extrusion mold, which is the mouthpiece. Then, the machine extrudes the plastic like a syringe (this process is continuous, with a screw on the machine that will extrude at a speed), ...
