How to choose a suitable pipette tip?

The purchase of pipette should consider the following aspects of the problem

1. High quality performance
2. Unique volume control system
3. Consistent accuracy and repeatability
4. Reliable and durable
5. Ergonomic design

If a pipette can have either a variable capacity or a fixed capacity, it means that there is a variable range piston and a fixed range piston in a pipette. This means that the brand pipette offers users two functions at the price level of a single pipette. Some brands of pipette function is not limited to this, not only each pipette with a fixed capacity piston, and you can also buy other range of fixed pistons installed on the pipette, the price is much lower than the price of buying a fixed range pipette.

The ability of pipette to combine with Tip head is appropriate

The combination of pipette and Tip head is the guarantee of accuracy and reproducibility, generally speaking, the combination of pipette and Tip is in the form of direct mouth, this method is more firm, but in the replacement of the Tip head needs to be more hard, over time for the combination of pipette and Tip head will have an adverse impact, there is a great possibility of affecting the sampling accuracy. Some brands of pipette equipped with double-layer O-rings, which can ensure that the sampling error is less than 1% of the set error. The O-ring makes the bond more precise, thus reducing imprecise errors. This pipette everyone in the purchase, may wish to make a reference, because this pipette can be suitable for more Tip heads.
