Quick release nut set

During the maintenance of the machine tool, several countersink pins are often encountered at the same time, as shown in Figure 1. Usually, we use the pullout device of the disassembly tool as shown in Figure 2. When removing the pin, string the nut sleeve 1 on the screw (not shown), then screw it into the screw hole of the pin, and then screw the nut sleeve onto the tie rod. When disassembling another pin, it is necessary to pull the nut from the pull.

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;
