Product Description

 

Product Description

Test tubes are divided into ordinary test tubes, test tubes with branches, centrifuge test tubes, etc.Our quartz products have the properties of high purity, strong transmission, small tolerance, etc.  They are widely used in semiconductor, optical communication, industry and other fields.

Test tube, a commonly used instrument in chemical laboratories, is used as a reaction container for a small amount of reagents. It should be used at room temperature or when it is heated (preheat before heating, otherwise the test tube may burst easily.).

Advantage

 

(1) The flat-mouth test tube is a flat-mouth glass tube with a round bottom, and the mouth of the tube is melted. Flat mouth, easy to disinfect and kill bacteria in the mouth.

(2) The roll mouth test tube is a round bottom glass tube with a curled edge (or round mouth) at the mouth. The roll mouth (or round mouth) is used to increase the mechanical strength and at the same time facilitate clamping and not easy to fall off.

Main purposeedit
(1) Take liquid or solid reagents
(2) Heating a small amount of solid or liquid
(3) Reactor for producing a small amount of gas
(4) Collect a small amount of gas
(5) A solute that dissolves a small amount of gas, liquid or solid. (6) As a container during centrifugation
(7) Used as a reaction vessel for a small amount of reagents, used at room temperature or heating

We can provide test tube, beaker, evaporating pan, crucible, funnel, washing cylinder, measuring cylinder, volumetric flask, etc.
