Within a chemical laboratory there are several instruments that you will need to use, such as chemistry pipettes.
Chemistry pipettes allow the transfer of a volume generally no greater than 20 ml from one container to another in an accurate manner. This is if you find yourself with the common denominator of the manufacturers, but if you look in Kalstein there is a pipette for transfer chemistry with a capacity of 23 ml.
Now, in general they allow to measure aliquots of liquid quite accurately. They’re usually glass. It consists of a transparent tube that ends at one of its conical tips, and has a graduation (a series of engraved marks) indicating different volumes.
Part of selecting the most appropriate ones is part of your criteria to choose the best manufacturer, the most important thing is that they are manufactured with high standards of quality and precision. The difference between successful and mediocre work is linked to the use of different laboratory instruments.
Do you know how to handle the pipettes chemistry?
- The liquid is aspirated through a slight vacuum using a suction bulb or tip, never the mouth.
- Make sure there are no bubbles or foam in the liquid.
- Clean pipette tip before transferring liquid
- Fill the pipette over the graduation mark and transfer the desired volume. The edge of the meniscus should be over the graduation mark.
