Method for measuring the diameter of a cone by an inner diameter dial gauge

The plug gauge is a commonly used gauge for measuring the diameter of a taper hole. However, in actual use, the size of the taper hole to be measured is different due to the different force, and the larger the diameter of the taper hole, the more prominent the problem. In order to solve this problem, we use a plug gauge to check the taper for the taper hole in the range of 50-250mm, and then use the inner diameter to replace the plug gauge to measure the taper hole diameter, and the effect is good. The advantage of this method is: measuring the cone

Centrifuge Test Tube

The advantage of the plastic centrifuge tube is that it is transparent or translucent, its hardness is small, and the gradient can be taken out by the puncture method. The disadvantage is that it is easy to deform, has poor corrosion resistance to organic solvents, and has a short service life.

Plastic Centrifuge Tubes have caps, which are used to prevent sample leakage, especially when used for radioactive or highly corrosive samples. It is very important to prevent sample leakage; the tube cap also has a function to prevent sample volatilization. And support the centrifuge tube to prevent deformation of the centrifuge tube. When choosing this point, you should also pay attention to check whether the tube cover is tight, and whether it can be tightly covered during the test, so as to achieve the inversion without leakage;
