Pipette, how to choose a suitable type for your application?
Normal when you choose a pipette for your lab, accuracy and repeat-ability is the most important factors before purchasing. Therefore, it is mainly based on technical data provided by the manufacturer. But here is also to point out that do not easily trust the seller’s verbal commitment, be sure to check the written materials provided by the manufacturer.
Reliability and durability of the product: It is mainly depended on the composition material of the pipette. For the shell, it should have high impact resistance, corrosion resistance and low thermal conductivity (such as PVDF material); for the piston, there were mainly stainless steel, ceramic and plastic materials in the market. The Stainless Steel have a good mechanical property, long life, but not suitable for the pipette of strong acid and alkali; The Ceramic has a high corrosion resistance, but poor mechanical properties. High-quality materials often mean higher prices, so you need to consider the factors of the purchase price and the life of use when you buy a pipette.
