Metrohm^® 776 Dosimat—Dispenser/Diluter

The Multipurpose Dispensing Unit

The 776 Dosimat is an ideal tool designed to handle all basic liquid handling functions. Based on a titration dispensing system, it offers precise and reliable dispensing and dilution.

The ability to dispense preset volumes makes the 776 Dosimat an excellent tool for sample preparations. The optional pipetting system allows for dilutions down to volumes of 10 µl, making the 776 a valuable timesaver for creating and re-creating standard solutions for other analyses including voltammetry, ICP, AA, HPLC or spectroscopy.

Solutions can be created directly from sample weights and the appropriate amount of solvent. Manual titration can be taken a littler further with automated calculations based on the volume of reagent dispensed. The closed reagent system, automatic refill and PTFE delivery tip enable you to perform clean, safe and accurate dilutions and dispensing. With an internal memory, the 776 Dosimat can store up to 10 separate dispensing/dilution methods.
