Total energy consumption

The total energy consumption refers to the sum of various energy sources in the material production sector, non-material production sector, and life consumption in a certain period of time. Including raw coal and crude oil and their products, natural gas, and electricity, excluding the use of low calorific value fuels, biomass, and solar energy. Total energy consumption is divided into three parts: terminal energy consumption, energy conversion conversion loss, and energy loss.

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;
