As a kind of common laboratory tool, pipettes are used to transfer liquids from one container to another in exact and measured volumes. They may seem like very important tools, but pipettes actually are a great invention to scientific research. Before they came to use about 50 years ago, scientists sometimes had no other choices but did the same job with their mouths.
We can find two types of Pipettes come: volumetric and measuring. Working as simple glass tubes, volumetric pipettes are used to transfer the specific amount of liquid. Measuring pipettes are adjustable, and you can draw up exact volume of liquid as you desire. You should place the pipette 1/4th of an inch from the bottom of the container when you draw it in a liquid to prevent damage. After you draw up the required volume of the liquid , you’d better gently tap the side of the pipette to remove excess droplets and hold the pipette at a 10 to 20 degree angle when you dispense.
Hawach pipettes include both electronic and mechanical types. We also have pipette stand ( linear and round), and pipette tips which are divided into advanced pipette tips, standard pipettes, and advanced filter pipette tips. Manufactured from innovative materials, Hawach guarantee all the products high temperature and pressure resistance, high accuracy, and easy-operating.
Pipette terms

The range of the pipette can be fixed and adjustable, such as 5 microliters fixed, that is, the pipette can only shoot 5 microliters of liquid at a time.
The range of the pipette can be fixed and adjustable, such as 5 microliters fixed, that is, the pipette can only shoot 5 microliters of liquid at a time.
5-50 microliters adjustable: you can adjust from 5, 6, 7 all the way to 50, each time the liquid is set by you.
