Product news

Metrohm Dosimats make the routine handling of liquids in day-to-day laboratory work much easier. They prove highly useful for various dosing and liquid handling tasks in laboratories all over the world. The new Dosimat plus can be operated manually as stand-alone instruments or used together with Titrino and Titrino plus models as well as the 781 pH/Ion Meter.

The new Dosimat plus offers four different modes for the most popular Liquid Handling applications in the routine lab:

DOS (Dosing)
Push-button dosing, particularly suitable for carrying out manual titrations with a color indicator.
From the added volume the result is calculated automatically and a report can be printed out.

XDOS (Extended Dosing with Tandem mode)
Adding a fixed volume: the volume and the dosing rate are predefined.
Time-controlled dosing: the volume and the time are predefined.
Dosing by dosing rate: the dosing rate and the time are predefined.

CNT D (Content Dosing)
This mode is used for the preparation of standards and other solutions. From the amount of the starting substance (solid or stock solution) and the predefined target concentration, the 865 Dosimat plus automatically determines the volume of solvent to be added. After dosing has taken place, a report containing all the relevant information about the prepared solution can be printed out.

LQT (Liquid Transfer)
This mode is used for pipetting and diluting liquids.

pH Meters and ElectrodesIon and pH meters are electrochemical equipment used to measure the pH (acidity or alkalinity) or specific ion concentration of a solution. Other meters can also measure the conductivity or dissolved oxygen content of a solution. pH meters, specific ion meters, conductivity meters and dissolved oxygen meters can come as benchtop or portable equipment. A meter’s electrodes can be replaced with easy to clean electrodes or electrodes for difficult media. pH, ion and conductivity meters are typically used in life science research, pharmaceutical testing, food and beverage, environmental and water analysis. Find the best pH meters and electrodes in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Pipettes and DispensersPipettes and dispensers are essential lab equipment used to dispense measured volumes of liquid accurately. Explore a range of manual and electronic pipettes, including single and multichannel, serological and volumetric pipettes, as well as a range of pipette tips. Bottle-top dispensers are also available for simple and fast solvent dispensing. Find the best pipettes & dispensers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.pH and Conductivity MetersIon and pH meters, used for electrochemical techniques and measurements, measure the concentration of specific ions using electrodes (probes) and a meter. Features of ph and ion meters to consider include temperature compensation, auto-calibration, adjustable resolution, measurable range and accuracy. Meters can be handheld, portable, benchtop and modular.TitrationTitration is an analytical technique for determining substance concentration in a solution. For titration consider a manual or automated system, volumetric or coulometric reagent addition and indication by a potentiometer, spectrometer, turbidometer or by the Karl Fischer method. Other features of titration to consider include burettes, reagents, concentration range, reaction time and autosamplers.
