High Strength And Anti-Leakage Tall Glass Cover Electronic Analytical Balances
 

Analytical balance is the most important instrument for accurate weighing in experiments, and it can be divided into mechanical and electronic. Mechanical analytical balances can be subdivided into ordinary analytical balances, air damping balances, semi-automatic photoelectric balances, fully automatic photoelectric balances and single-tray balances. These balances all use the principle of leverage, but differ in structure and method of use. The mechanical balance can meet the accuracy requirements of general quantitative analysis, with a sensitivity of 0.1 mg. The biggest advantage of this type of balance is its intuitive structure, but the balance parts are complicated, and the operation is demanding and time-consuming
 

Weighing method
 

(1) Direct weighing method: If the so-called solid sample is not hygroscopic and stable in the air, the direct weighing method can be used. First accurately weigh the mass of the clean container on the balance, then take an appropriate amount of sample with a medicine spoon and add it to the container, and weigh its total mass. Subtract the two mass values to obtain the mass of the sample.
(2) Decrement method: Weighing on an analytical balance generally uses the decrement method. First weigh the exact mass of the sample and the weighing bottle, and then pour a part of the sample in the weighing bottle into the container to be filled with medicine until the estimated amount is close to the required amount. Cover the weighing bottle after pouring the medicine, put it on the balance and weigh its mass accurately. The difference between the two masses is the mass of the sample. If too much medicine is poured into the container at one time, the weighing must be discarded and never put back into the weighing bottle. If the poured sample is not enough, add one more time, but the frequency should be less.
(3) Specified method: For samples with relatively stable properties, sometimes for the convenience of calculation, samples of specified mass can be weighed. When using the designated method to weigh, put a watch glass on both sides of the balance pan (their masses should be as close as possible), adjust the balance point of the balance to be around the middle scale, and then add a weight with a fixed mass to the left balance pan. Add the sample to the balance pan on the right (it is more convenient to take and place the sample) until the balance point of the balance reaches the original value, at this time, the mass of the sample is the specified mass.
