First, what is osmotic pressure? The semipermeable membrane is separated, one of which is the solvent water, and the other is the solution, and the water permeates through the semipermeable membrane to the solution side. The pressure applied to the solution side to prevent the movement of water is called the osmotic pressure. The reason

1. Sterile homogenizer Disconnect the power supply and disconnect the plug if it is not used for a long time. Prevent the aging of electronic components inside the aseptic homogenizer. 2. Do not open the sterile homogenizer door when working on the hammer plate to avoid overflow of the sample liquid. It should be built

Pipettes are instruments commonly used in biological and chemical laboratories to remove trace amounts of liquids. The advantages are easy to operate and high accuracy. With it, laboratory pipetting is no longer the main reason for analysis errors. For those things you have to know about pipettes, see below! 1. The pipette is an upgraded

The systematic error is also called the regular error. It is that under certain measurement conditions, when the repeated measurement is performed on the same measured size, the magnitude and sign of the error value (positive or negative value) remain unchanged; or when the condition changes, it changes according to a certain law. Error; the

What is high salt wastewater? High-salt wastewater refers to wastewater with a total salt content of at least 1%. It is mainly from chemical plants and oil and gas collection and processing. This wastewater contains a variety of substances (including salts, oils, organic heavy metals and radioactive materials). Treatment of high-salt wastewater: Evaporation method, electrochemical
