The balance is the oldest measuring instrument for weighing the quality of objects. It has been in existence for more than 4,000 years and has evolved from simple to complex, from low accuracy to high accuracy. According to the structural principle of the balance, the balance can be divided into four categories: torsion balances, hydrostatic balances, lever balances and  electronic balance s . As the most basic equipment for weighing in the microbial testing laboratory, the balance should be selected according to the difference between the weighing object and the weighing accuracy requirements, and the balance of the laboratory should be used to balance the weight of the object. Electronic balance. Compared with mechanical balances, electronic balances in the laboratory have the characteristics of accurate weighing, frequent display and fast and clear display. They also have functions such as calibration, digital display, automatic peeling, automatic data output and automatic fa...

Analytical balances  are one of the most important instruments in quantitative analysis. Before starting the analytical work, you must be familiar with how to use the analytical balance correctly, because the accuracy of the weighing has a great influence on the analysis results. Commonly used analytical balances have semi-automatic electro-optical balances,  automatic error correction analytical balance , single-disc electro-optical balances, and micro-days. These balances are somewhat different in structure and method of use, but the basic principles are the same. A technologically advanced electronic balance is also applied.  Analytical balance supplier  today to share with you the laboratory balance, what are the specifications? hope that it can help us. Let’s take a look. 0.0001g analytical density scale (1) The analytical balance is a precision instrument that needs to be installed in a dedicated balance room. The balance chamber should be separated from...

In theory, it is best not to put a desiccant in the  balance . First, it will cause environmental differences between the inside and outside of the balance; more importantly, the humidity in the balance will decrease, and static electricity will be generated when the glassware is weighed, and stable readings will not be obtained, especially in winter. In the past  analytical balances , the interior of the photoelectric balance was a weight, and the moisture (especially the weight) caused inaccuracies in weighing. Now the principle of electronic balance is pressure sensor, which keeps the temperature stable by power on. If the humidity and temperature inside the balance are different from those outside, will the weight inside be the same as those outside? The electronic balance cannot be used with a desiccant when using an accuracy of 0.01 mg. Due to the presence of the desiccant, a slight air flow is generated in the balance, so that the balance cannot be stabilized....

The  electric scale precision balance  belongs to the electronic balance with high precision in the electronic balance. The instrument is equipped with high-precision weighing, so the accuracy and reaction speed of the instrument are very high. The precision electronic balance is widely used in research institutes, laboratories, etc. To do quantitative analysis. The principle of the precision electronic balance is to use the balance of electromagnetic force for weighing. Its weighing accuracy and reaction sensitivity far exceed the mechanical precision balance, but the precision electronic balance should be carefully maintained. It is very vulnerable to the outside world. Environmental, electromagnetic field, temperature, humidity and other factors, it is recommended that you pay attention to the relevant details in the use, in order to improve (the efficiency of the electronic balance, to ensure the accuracy of the weighing results. Electronic balance people use the electr...
