Main use and method of use of test tube
Nov 14, 2018

The reaction vessel is mainly used to complete the physical reaction and chemical reaction of the medium during use. Widely used in petroleum, chemical, rubber, pesticide, fuel, medicine, food, used to complete the vulcanization, nitrification, hydrogenation, hydrocarbonization, polymerization, condensation and other processes, our company can design and manufacture various pressure volumes according to customer needs. Reaction vessel products, various polymerization, cracking, hydrogenation, high pressure, synthesis and other reaction vessels, fermenters, etc., generally carbon-manganese steel, stainless steel, zirconium, nickel-based (Half, Monel, Inconel) alloy and Other composite materials.

Test tube

The main purpose:

1 A reaction vessel used as a small amount of reagent under normal temperature or heating conditions.

2 Collect a small amount of gas and gas for verification.

3 hold a small amount of medicine.

How to use and precautions:

1 can be directly heated, clamped 1/3 from the mouth of the test tube with a test tube holder, from the bottom to the top (to prevent contamination of drugs).

2 The specifications of the test tubes are large and small. When not heated, the liquid contained in the test tube does not exceed 1/2 of the volume, and does not exceed 1/3 when heated.

3 The outer wall should be free of water droplets before heating; it should not be quenched after heating to prevent the tube from rupturing.

4 When heating, first make the tube evenly heated, then concentrate heating, the tube mouth should not deal with anyone. When heating the solid, the tube is placed horizontally, the nozzle is slightly inclined downward, and the solid is laid flat on the bottom of the tube. When heating the liquid, the test tube is oriented, and the test tube is at a 45° angle to the table top.

5 Do not use a test tube to heat a strong alkaline substance such as NaOH.
