What should be considered when purchasing the bottle-top dispenser?
Products must be reliable and durable
This aspect depends primarily on the materials used in the pipette. For example, the outer casing should have high impact resistance, corrosion resistance and low thermal conductivity (such as PVDF material). Of course, quality materials often mean higher prices, so you need to consider the factors of purchase price and longevity.
That is, the accuracy and repeatability of the dispenser
For most users, it is difficult to detect product performance before purchasing. Therefore, it is mainly based on the technical data provided by the manufacturer to carefully check the written materials provided by the manufacturer.
The bottle-top dispenser can be used for continuous pipetting. For more convenient operation, a universal outlet tube with a safety handle can be used, even if it is pipetted into a very thin tube. In addition, some brands of products have also designed safety valves. The unique safety valve uses internal circulation to eliminate air bubbles, avoiding reagent waste, and the valve handle can clearly show the valve opening and closing state.
