765 Dosimat: Precision Dosing for Medical Laboratories
The 765 Dosimat from Metrohm is a volumetric dosing device designed for environments requiring precise and reliable distribution of liquids, such as medical, pharmaceutical or clinical laboratories. It is based on motorised piston technology combined with exchange units suitable for different volumes, ranging from 1 to 50 mL. This device allows users to perform a wide range of operations, including manual dosing in real time (DOS mode), repeated dispensing (DIS R), cumulative dispensing (DIS C), pipetting (PIP), dilution (DIL), and the preparation of solutions with a defined concentration (CNT D).
It is operated via an intuitive interface with a 16-character display and a full or partial keypad. The <FILL>, <CLEAR> and <CLEAR> keys are used to fill, reset and start the respective functions. The dosing can be set digitally or analogously via a potentiometer on the front panel. The device also has a user memory that can store ten modes with their customised settings.
For medical laboratories, the accuracy of the 765 Dosimat translates into rigorous control of the volumes delivered, with a resolution of up to 0.1 µL depending on the unit used. This accuracy is essential for biological sample dosing procedures, the preparation of standards, or the dilution of drugs to specific concentrations.
The 765 Dosimat can be connected to peripherals such as electronic scales, printers or stirrers via its RS232 interface. It also supports remote control for integration into automated systems. Thanks to its integrated calculation functions (blank value, factor, sample mass), it can provide results in various units (ppm, %, g/L, mol/L, etc.) while minimising the risk of transcription errors.
The device is protected against power surges, has non-volatile memory to retain settings even when powered down, and allows diagnostic tests in the event of malfunction. The 765 Dosimat is therefore a reliable choice for healthcare professionals seeking to standardise their liquid processes with rigour.
