Metrohm^® Coulometric Karl Fischer Titrators^®

Sometimes the smallest details can lead to the biggest successes. The right accessories can complete your titration system, and Metrohm has a full line of accessories for the KF coulometers. Here are some of our favorites—designed to improve safety in the lab and make your titrator more efficient.

703 Pump/Stirrer

The 703 Pump/Stirrer is useful for all titrations and especially for Karl Fischer titration. It has a built-in stirrer and an integrated membrane pump that can be used to aspirate or add solvent without opening the cell. That translates to increased lab safety and reduced conditioning times.

Automatic reagent exchange

Connecting a 700 Dosino to the KF coulometer allows you to automatically exchange used reagent in the cell with fresh reagent. With one press of a button, the Dosino siphons off the spent reagent, rinses the cell and adds fresh reagent. Since the cell does not need to be opened during this operation, no humidity enters the cell and the time to recondition the cell is minimized.

Karl Fischer ovens

A KF oven is recommended for samples that cannot be introduced directly into the KF cell (e.g., solids, samples not miscible in KF solvent). The 832 KF Oven can be used to process individual samples, one at a time. The 774 Oven Sample Processor is the ideal solution for analysis of up to 35 samples.

Tiamo™ titration software

We call it “titration and more” because this flexible, intuitive software combines titration, automation and third-party instruments with logic, multitasking and more.

Reagents

A Karl Fischer titrator is only as good as the reagents you use with it. For over 20 years, chemists have trusted the Hydranal^® line of Karl Fischer reagents. You can purchase the complete Hydranal line directly from Brinkmann.

Balances

When you connect a balance directly to your KF titrator, the weight is transferred with the touch of a button—eliminating potential errors due to manually entering the weight on the keypad. We recommend either Mettler Toledo^® or Sartorius^® analytical balances with a readability of at least 0.1 mg for volumetric Karl Fischer titration.
