D-50 Automatic Diluter

D-50 Automatic Diluter

Short Description:

Dilution operation is a common chemical experiment operation, which is often used to prepare standard curve series solutions, or to prepare high-concentration solutions into low-concentration solutions.




Designed for precision liquid handling such as laboratory precision dilution,standard curve making and standard sample preparation, biological agents precise dosing, etc.


The precise technology of constant volume supports a wide volume range from 0.4 mL to 3000 mL, and the minimum resolution reaches 0.01mL.

The maximal dilution ratio reaches up to 7500, meeting various requirements of our users.

The relative standard deviation of the precision is only 0.1% while the target volume is 100 mL.

The temperature compensation function to eliminate the influence of the density difference of the solution at different temperatures and ensure the accuracy and stability of the pipetting. The relative error is ±0.5%, and the accuracy is much higher than the Class A volumetric flask and manual dilution.

Simple Operation: The dilution parameters do not need to be calculated manually, just input the "original solution concentration, target volume, target concentration", and the whole process is automated.

Safe and Reliable: the experimenter no need to touch too much high-concentration standard samples , which minimizes the chance of experimenter coming into touch with chemical reagents.
