For the pipetting operation of common aqueous solutions in the laboratory, such as water, buffer solution, diluted salt solution, diluted acid/alkali solution, etc., the gas piston pipette commonly used in the laboratory can basically meet the experimental needs.
Gas piston pipette
However, in the experiment, we also use some liquids with different properties from water, such as viscous liquids, liquids with large density differences from water, volatile liquids, hazardous samples, precious sample liquids, surfactant containing solutions, and easily foaming solutions. For these special liquids, gas piston pipettes often cannot guarantee the accuracy or safety of pipetting. At this point, an external piston type liquid separator is a good solution because its piston is in direct contact with the sample without an air column, ensuring that the accuracy of liquid transfer is not affected by the density, viscosity, and volatility of the processed liquid, and does not cause cross contamination.
External piston pipette
BIO-DL Stepper continuous distributor is a brand new manually adjustable continuous distributor that uses an external piston working principle, allowing you to quickly and accurately perform repetitive pipetting operations. Easy to operate with one hand, it can continuously divide the liquid 44 times after one suction, with strong versatility, allowing you to flexibly and easily apply it in different multiple aliquots of liquid. The excellent separation experience and super high cost-effectiveness make special pipettes no longer a concern.
Advantage of BIO-DL Stepper continuous distributor:
The use of an external piston working principle is an ideal choice for removing high viscosity or volatile liquids.
Adopting excellent ergonomic handle design, it can easily separate fluids with one hand and reduce RSI risk.
The separation volume is flexible and lightweight, with a separation range of 10 μ l-5000 μ l and up to 35 continuous separation functions, saving time for repeated separation and meeting your separation needs.
Adjusting the position of the wheel is completely suitable for one handed operation, with a convenient range setting board display that provides intuitive references for the volume of liquid separation, the size of the liquid separation syringe, and the number of liquid separation steps.
By using innovative and sophisticated materials as well as robust structural design, precise and accurate continuous liquid separation can be quickly carried out for your high-quality experience.
