Valco Instruments Co. Inc. - M Series Diluter/Dispenser

The Cheminert® M Series Diluter/Dispensers simplify the sample preparation process for dispensing and diluting liquids. The user-friendly Wizard format eliminates all the math calculations and external charts associated with diluting and dispensing applications. Just enter the dilution ratio and the final volume, and the correct volume is calculated and automatically dispensed. For multiple dispenses, simply enter the volume and number of dispense repetitions, and the Wizard calculates the total volume to be aspirated. It's that easy!

Two models are offered – the M10 with a flow range of 10 nl to 10 ml, and the M50 with a range of 50 µl to 50 ml.

The diluter/dispenser is built around a patented syringe-free, bi-directional, positive displacement pump. This design approach gives the largest volume range available, and eliminates the inconvenience of having to change and refill syringes. A multiposition stream selection valve can be easily integrated with the pump for multi-solvent applications.

Other features include a smart hand probe that signals the operator when an aspirate or dispense step is completed, enough memory to store 64 programs, and a small fooprint that takes up a minimum of bench space.
