  When the   0.01g lab electronic balance   used, the weighing is always inaccurate? Do you have a good analysis of what caused it? In general, there are many reasons for the inaccurate weighing of samples in laboratory analysis, which can be roughly divided into several reasons such as analytical balance calibration, installation, environmental and physical factors of the sample, and improper operation. 1.The Analytical Balance Has not Been Calibrated Before Use Before using an analytical balance, you must first confirm its correctness, otherwise the correctness of the balance cannot be guaranteed. Analytical balances should be calibrated regularly from the first use. Balances that are used continuously are calibrated approximately once a week. Calibration should be carried out in accordance with the specified procedures, and standard weights must be used for calibration, otherwise the calibration will not be effective. 2.Incorrect Installation of Analytical Balance When...

  Question 1. Does the laboratory have to establish a special balance room to place one-thousandth of the balance? Can it be directly placed on a separate sky platform in the testing room? The environmental condition requirements of this level of balance are generally that the temperature is not more than 30 degrees Celsius, the humidity is not more than 85%, and the temperature difference during operation does not exceed 5 degrees Celsius; but whether it can be directly placed in a separate overhead platform in the testing room should also consider whether the room is There are corrosive gas, vibration and air flow, etc., if all are satisfied, it can be released. Question 2: Should the silica gel in the  laboratory balance  be replaced regularly, and how often should it be replaced? Experts suggested not to put desiccant in the balance, but to control the temperature and humidity in the balance. If you really want to put it, it is based on the actual situation, and half ...
