665 Dosimat: High-Precision Medical Dispenser for Clinical Laboratories
The 665 Dosimat from Metrohm is a volumetric dispensing instrument designed for medical environments that require maximum precision in the handling of liquids. Whether preparing solutions of exact concentration for biomedical analysis, pipetting very specific volumes for diagnostics, or controlling dosages for clinical research, this model offers consistent stability and reliability.
It has six operating modes that cover all the needs encountered in medical laboratories: dosing (DOS), repeated dispensing (DIS R), cumulative dispensing (DIS C), pipetting (PIP), dilution (DIL) and preparation of solutions with a defined concentration (CNT D). Each mode allows precise control of the dispensed volume, aspiration or expulsion speed, and offers automated calculations based on parameters such as dilution factor, blank volume or sample size.
Connection to an external balance and a magnetic stirrer completes its functionality for integration into complex dosing chains. Data can be transferred via the RS232C interface, facilitating documentation and traceability in accordance with standard procedures (GLP/ISO 900X).
In a medical context, the 665 Dosimat stands out for its ability to produce accurate solutions without loss of raw material, its ease of use via a dedicated keypad and its speed of execution. It is particularly useful for preparing standards, managing experimental infusion solutions or automating clinical analysis protocols.
Thanks to its modular design, the 665 Dosimat can be combined with different volumes of exchange units (from 1 ml to 50 ml), allowing precise adjustment according to experimental requirements. In particular, it helps to avoid human error during the preparation of sensitive solutions, making it a major asset in environments where traceability and reproducibility are essential.
In medical analysis laboratories, it can be used for the automated dilution of biological samples, the preparation of standard reagents or the precise transfer of liquids between tubes or vessels, while ensuring optimal safety via programmable safety volumes. This level of control is crucial for protocols subject to strict standards, such as those under GLP, GMP or ISO 9001.
