Without Diaphragm for Ease of Use

The C20SX generator cell comes without a ceramic diaphragm, providing faster analysis speed, lower drift and minimal cleaning for a large variety of samples.

Safe Chemical Handling

Reduce user contact with chemicals by automatically draining and refilling the titrator cell and preventing waste overflow with dedicated accessories.

Secure Operation

Designate "Expert" and "Routine" user groups to allow full or limited access to titrator operations. A simple intuitive interface prevents differences or errors between users.

Manual Oven Option

Add a DO308 manual drying oven to fully release water from tricky samples. For single solid, viscous or poorly soluble samples like powders, granules, plastics, fibers, pastes, wool, tar, coal, and more.

The DO308 drying oven is the ideal accessory for the METTLER TOLEDO volumetric or coulometric Karl Fischer titrators.

It allows easy and accurate water determination of solid or viscous samples.

Material No.: 51371200

The external DV704 titration stand can be used for volumetric and coulometric Karl Fischer titrations and for potentiometric titrations. The titration stand includes a magnetic stirrer and can be employed with all Excellence and Compact titrators from METTLER TOLEDO.

The DV704 can be optimally combined with the Solvent Manager to change solvent easily, safely, and without operator contact, for example for the Karl Fischer titration. All the usual titration accessories such as sensors, standard beakers or overhead stirrer can of course be directly utilized with the DV704 or with the external titration arm.

Same samples are hard to work with because they stick to everything. With common tools it is almost impossible to get all the material that was weighted into the titrator. That is why METTLER TOLEDO designed the Visco-Spoon.
