As a common laboratory equipment, pipettes are designed to measure the volume of liquid and draw it to drip into other containers. Often used in biological experiments or chemical experiments. How to detect the leak of the pipette during the experiment?
Detection method:
1) Visual inspection: first pipette the liquid using the pipette to be tested, then let it stand vertically for 15 seconds to see if there is a slow flow of droplets. If there is a droplet flowing slowly, it means that the pipette has air leakage.
2) Pressure pump detection: Use a dedicated pressure pump to detect the pressure and determine if the pipette is leaking.
Analysis of the cause of air leakage:
1) First, check if the tip is matched? It is recommended to use original matching tips. If it is not the original matching tip, it is best to consult the manufacturer or agent to see if the tip you are using matches the pipette used.
2) Secondly, is there any tightening when assembling the tip? It is very likely that the pipette leaks due to the lack of tightening when the tip is loaded.
If no problem is found in either of the above cases, it is likely that the inside of the pipette is not airtight. At this time, you need to contact the pipette company maintenance engineer. For more information about pipettes, please contact Shanghai Baqi Industrial Co., Ltd.!
