Precautions for purchasing dynamic BET specific surface area tester The use of specific surface area tester requires certain environmental conditions.
Before the specific surface area tester, the specific precautions that need to be understood are:
1. It is best to have an independent laboratory, separated from other instrument rooms to avoid mutual interference between instruments.
2. To have an independent test computer, ordinary configuration is sufficient.
3. The laboratory is best equipped with an air conditioner to ensure a constant temperature in the laboratory.
4. The laboratory should be far away from the factory production workshop. It is not suitable to put the instrument in a place with much dust and large vibration.
5. Buy an electronic balance of one ten thousandth of a gram or an analytical balance with the same weighing range and a physical balance. And a small spoon for weighing, weighing paper, drying dish (preservation of standards and samples).
6. It is best to have a constant temperature ultrasonic instrument to clean the sample tube. Configure a highly oxidizing and strongly acidic acid to wash off the residual sample in the sample tube. A constant temperature heating oven is required to dry the sample tube.
7. It is best to have a regulated power supply to provide a stable voltage for the instrument to avoid interference caused by voltage instability. At the same time, ensure that the connected power supply is grounded.
