The invention relates to the field of laboratory appliances, and in particular discloses a chemical metering device for laboratory control, including a metering box, a partition is arranged inside the metering box, a weighing device is arranged at the bottom of the metering box, and the metering box The inner wall of the upper end is provided with a clamping assembly, and the clamping assembly includes a round hole arranged on the upper side wall of the metering box, and a rubber bag adapted to the round hole is arranged on the outer side of the upper end of the metering box, and the rubber bag A gripper is sleeved inside, and the gripper includes a fixed gripper and a moving gripper. The laboratory control chemical metering device provided by the present invention is provided with an air inlet and an air outlet, through which nitrogen gas can be fed through the air inlet to discharge the air in the metering box, reducing the contact between flammable solids and air; There are convertible clamps, which can not only realize the clamping of flammable solids, but also realize the decomposition of flammable solids, so that the required chemicals can be weighed out quickly and accurately.
Description
technical field [0001] The invention relates to the field of laboratory supplies, in particular to a metering device for laboratory controlled chemicals. Background technique [0002] Chemicals have different characteristics such as flammability and volatility. For laboratory chemicals, chemicals with different characteristics also have different storage and handling methods. When storing and taking, great care must be taken. Among them, For the controlled chemicals of flammable solids, such as yellow phosphorus, great care should be taken when taking them according to the metering, and the existing metering devices for laboratory controlled chemicals have certain disadvantages when used. [0003] When taking flammable solid controlled chemicals, not only must the measurement be accurate, but also the weighing speed must be fast to avoid spontaneous combustion caused by flammable solids being in contact with air and moisture for a long time and friction. When taking flammab...
