Standard suction head:

The most common type of suction head, is also the most widely used suction head, almost all pipetting operations can be used, this is the most economical type of suction head, if there is no special requirements, the general use of standard suction head can meet most of the pipetting needs. Other types of suction heads also evolved from the standard common suction head. Standard head general packaging form is more, the market common bag, box, preloaded board (stacked) three. Generally speaking, the box will provide sterilized finished products, while the bag and preloaded plate will provide sterilization less. When using, if the user has special sterilization needs, he can directly purchase the sterilized box, or put the unsterilized bag suction head into the empty suction head box for self-sterilization and then use. Most of the suction heads and suction boxes on the market are made of PP polypropylene, so they can be processed at high temperature and high pressure in a sterilized pot.

Low adsorption suction head:

No matter what type of suction head is selected, low residual rate is a key. If we carefully observe the use process of the suction head, we will find that there is always a part of the liquid can not be discharged and remains in the inside of the suction head. No matter what experiment is done, this will cause certain result errors. If the error is within the acceptable range, the ordinary suction head can still be selected for use. For experiments requiring high sensitivity, or precious samples or reagents easy to remain, low adsorption head can be selected to improve the recovery rate, in order to obtain more accurate experimental results and a higher recovery rate for precious samples. The surface of the low adsorption suction head has been hydrophobic treatment to reduce the surface tension of the liquid in the suction head left more residue. Although this sounds pretty good, it is rarely used in practice. Because as a very large laboratory consumption of a class of products, the cost of the head is also a factor that users will consider, this kind of special treatment of the head, its price is indeed more expensive than the standard head.
