Reagent Dosing à la Carte

It's Your Choice!

Titrating means dosing intelligently. The Titrando System gives you the choice. With the 809 Titrando you dose with Dosinos and Dosing Units that are attached directly onto the reagent bottle. With the 808 Titrando dosing is carried out by using Exchange Units. One of these is located on the 808 Titrando, which can control additional Dosimats with their Exchange Units.
Mixed systems with Dosing and Exchange Units are possible. This means that your choice doesn't lead you down a blind alley - full flexibility is retained.

Two 800 Dosinos with 807 Dosing Units on top of the 809 Titrando.

The 806 Exchange Unit - a Time-proven Concept with added Intelligence

Since 1973 Metrohm has produced Exchange Units with automatic valve switching. The Exchange Unit has been continuously developed. The latest version is the 806 Exchange Unit. It dispenses reagents with the unique resolution of 20 000 steps per cylinder volume. The integral Data Chip makes it intelligent; this chip contains all the data required on the reagent and the Exchange Unit. The Titrando acquires these data automatically.
Every Exchange Unit carries a serial and a cylinder number and is delivered with an individual certificate.

The Dosino - Space-saving Modernity

The Dosinos with its Dosing Unit can be mounted directly onto the reagent bottle. This means that dosing requires no additional bench space. Thanks to adapters, any reagent bottle can be used directly.

The Dosino houses the latest state-of-the-art electronics and micromechanics. The Dosing Unit can be exchanged within seconds. Thanks to its transparent housing any bubbles that may be present in the dosing cylinder can be seen immediately and the valve position is always shown. Rinsing and preparation of the Dosing Unit can be carried out automatically; manual dismantling and rinsing are not necessary.
