First, let's talk about the origin of the name "gun head". To compare the laboratory to the battlefield, the pipette is the gun in the hand of the experimental er, and the disposable replacement suction head becomes the "bullet", that is, the "gun head".

Pipette suction head is highly transparent polypropylene (PP) material, can be high temperature and high-pressure sterilization, according to the specific laboratory requirements to decide whether to sterilization, you can also buy has been sterilized good suction head.

The packaging of the suction head is bagged in bulk, stacked, boxed, I believe that many friends in the biological laboratory have had the experience of "inserting the gun", in a good day, two or three friends, a big table, the same as the hill of the suction box, first carefully clean the desktop, spray on a layer of alcohol, and so on it naturally dried after an afternoon of inserting the gun. Many laboratories now have sufficient funds, and it is better to use boxed suction heads directly.
