Metrohm 774 Oven Sample Processor KF Karl Fischer Coulometric Volumetric Titrator

Description

This is a pre-owned Metrohm 774 Oven Sample Processor in excellent condition.

The Metrohm 774 Oven Sample Processor is used for a wide range of applications. It provides an essential service when large numbers of samples have to be processed in which the samples require to be heated and/or whenever it is necessary to remove moisture or organic solvents from solids or liquids by the application of heat.

The construction of the 774 Oven Sample Processor is principally based on the determination of moisture by the oven method. The sample heated in the oven block releases its moisture as water vapor which is transferred to a measuring cell in a stream of gas. The moisture determination in the cell (not included) can be carried out either coulometrically or volumetrically according to Karl Fischer.

It is compatible with the wide range of Metrohm titrators, meters and dosing instruments via its parallel remote interface and its serial RS232 interface, but that it can also control or be controlled by any instrument which is equipped with a suitable communications interface.
