The accuracy of laboratory pumps is a crucial part of experimental work. Calibration is an essential step to ensure the accuracy and reliability of the pump during the experiment. This article will provide you with a comprehensive guide to the key steps of laboratory pump calibration, from pre-calibration preparation to calibration methods.
1.Preparation before calibration.
Before calibrating the lab pump, make sure that every detail is properly taken care of to ensure the accuracy of the calibration. First and foremost, the pump must be installed securely and correctly, while the pipe connections need to be strong and reliable to prevent any unnecessary leaks. In this step, parameters such as power supply, voltage, and current are carefully checked to ensure that the pump is functioning properly during the calibration process. At the same time, prepare the tools and equipment required for calibration, including but not limited to reference materials and standard containers.
2.Calibration method.
1) Calibration of reference materials.
The deviation between the actual output concentration and the concentration of the reference material is measured, so as to ensure the concentration accuracy of the pump. It is important for the user to use high-purity reference materials and to ensure that the pipes are tightly connected to prevent gas leakage from affecting the measurement results.
2) Standard container calibration.
The pump is calibrated using a standard vessel of known volume, and the deviation of the actual output volume from the standard container volume is measured to ensure the volumetric accuracy of the pump. In the calibration process of standard vessels, it is necessary to use a high-precision volumetric meter and ensure that the pipes are unobstructed and that fluid resistance does not interfere with the measurement results.
By carefully calibrating and calibrating laboratory pumps, we can ensure their accuracy and reliability, thus supporting accurate measurements in the laboratory. When calibrating, follow the prescribed operating procedures and use high-precision tools and equipment for measurement. At the same time, regular maintenance and maintenance of laboratory pumps are carried out to ensure their normal operation and extended service life. This will provide you with more stable and accurate experimental conditions for your experimental work.
