A transfer pipette, also called a polyethylene dropper, is a tool used to transfer liquid samples.
When repeatedly dispensing the necessary constant amount of the sample in the valve after sucking up the liquid using capillary action.
It is mainly made of polyethylene material in a one-piece mold (one-piece molding). The long, flexible stem part is soft and bendable and can be used to suck up liquid from thin, small volume tubes. The lengths range from 51 mm to 239 mm, and the capacities vary from 20 µL to 3 mL.
Transfer pipettes are used in a wide range of fields, including research and development, medicine, nursing care, production, food hygiene, and the food and beverage industry.
Examples are as follows:
Various other applications are possible.
After pressing the valve part of transfer pipettes with a finger and dipping the tube or bottle into the sample, the sample is sucked up when the pressing finger is released. When selecting a product, it is necessary to take the suction capacity into consideration depending on the nature of the experiment.
A small amount of sample sucked up by the valve can be dropped into the valve section while pressing the valve lightly. one drop that falls should be selected in consideration of the contents of the experiment.
Polyethylene used as raw material is non-toxic with few eluted components.
Its low-affinity surface prevents loss of cells and valuable proteins through binding.
The pipette tips can be heat-sealed and stored directly at -40°C or frozen in liquid nitrogen
Individually packaged products after gamma sterilization or gas (EOG) sterilization prevent cross-contamination and can therefore be used for experiments performed under aseptic conditions.
