Volumetric KF Titrator MKV-710M

Volumetric Karl Fischer Titrator MKV-710M
Volumetric Karl-Fischer Titrator MKV-710M
The MKV-710M Volumetric Karl Fischer Titrator can be equipped with 2 burettes

Convenient operation, versatile, expandable: The MKV-710M comes with the largest titration user interface available in the market: The MCU-720M control unit of this model with its 8.4 inch LED touch panel offers an unique user experience and can serve as a common controller for up to four titrators of any type, be it additional MKV-710B volumetric or MKC-710B coulometric Karl Fischer moisture titrators or even AT-710B potentiometric titrators.

Increased workplace safety
With optional Bluetooth® adapters, there is no need for a cable connection between the control unit and the titrator. This offers substantial benefits in terms of safety as the main control unit can be located outside the hood when toxic samples have to be measured.

Unique flexibility
The MKV-710M is based on a new approach in terms of modularity. The core part of the system, the MCU-710M control unit, is a versatile, touch panel controlled titration work station which can control up to four KEM 710 titration units of any type. This saves space, time and money: If you need a system to perform coulometric Karl-Fischer moisture determinations or even potentiometric titrations in the future, you can easily upgrade your system without needing to invest money and waste valuable bench space for an additional display and spending time to get familiar with a new user interface.

Full GLP compliance
The MKV-710M offers comprehensive GLP functions which ensure that system performance checks are performed at regular intervals. Up to 100 records of system performance checks and Karl Fischer reagent factor determinations are stored in the MCU-710M control unit.

Details

Comfortable, safe and space-saving

The MKV-710M is the perfect solution for laboratories, where more than one titration system is in use or where one or several titrators need to be located in a hood for safety reasons: The MCU-710M control unit of the MKV-710M titrator can control up to 4 titrators simultaneously. It can be equipped with a battery and a Bluetooth® adapter for wireless operation. Like this it is possible to operate the titrators comfortably even if they are located in a hood – which offers substantial benefits in terms of safety when toxic samples need to be measured.

Important reagent information stored in the burette
The MCU-710M control unit of the MKV-710M and the MKC-710M titrator can control up to 4 titrators simultaneously.

Reagent information directly stored in the burette unit

Important reagent information such as type of reagent, factor, last factor determination etc. is stored in an IC chip directly in the burette unit. The titrator automatically detects whether the reagent used is suitable for the method selected, errors due to wrong reagent data are a thing of the past.

Substantial accuracy and reliability enhancement

High resolution burettes, small dead volumes: The MKV-710M titrator comes with all the prerequisites that ensure highly accurate results: The burette drives have a resolution of 20'000 steps. No more classical turning valve connected to the burette – a newly developed valve mounted directly on top of the burette offers substantial advantages: Less connecting tubes, which means less cross contamination when replacing the reagent and less room for air bubble formation.

Burettes still based on external three way turning valves
The burette of the MKV-710 Karl Fischer Titrators is based on a two way valve.

User groups and permissions

Two different user levels let you easily define the operation permissions of each operator. An administrator (protected with password) has access to all functions whereas a normal operator can only perform burette operation, calibration, measurement, method number (sample file) change and reading of method.

Always in top condition for highly accurate measurements

By adding an optional burette unit filled with a Water-Methanol standard solution, factor determinations are a matter of one single click. Thanks to a built-in timer function, factor determinations of the Karl Fischer reagent can automatically be performed at regular intervals.

The easy way to transfer your results directly to Microsoft EXCEL

The Data Capture Software is an easy to use and flexible solution to collect measurement results from different KEM instruments (Refractometers, Density Meters, Potentiometric or Karl-Fischer Titrators, Thermal Conductivity Meters) on a Windows personal computer.

  • Up to four different instruments can be connected to one single PC and be used simultaneously. Two of these instruments can be of the same model.
  • The results can directly be stored in EXCEL workbooks. The measured results are always available at a glance in a clear and concise manner.
    • As soon as a measurement has finished, the result appears in the corresponding worksheet.
    • The layout, order and the format how the results are stored in EXCEL can freely be adapted to specific needs.
    • Results can be automatically be processed by EXCEL macros as they are transmitted to the PC. Additional data (comments, sample data, etc.) can be entered at any time by means of the PC keyboard or a barcode reader.
  • All results can at the same time be stored in as CSV files.

Evaporator

ADP-611 Evaporator
ADP-611 evaporator

ADP-611: Accurate water determinations of difficult samples

The ADP-611 substantially broadens the application spectrum of your Karl Fischer Titrator. With this evaporator accurate water determinations of samples which cannot be titrated directly can be performed:

  • Substances which cause side reactions with the KF reagent such as copper (II) salts, iron (III) salts, nitrites, motor oils with additives, etc.
  • Substances that release water only at elevated temperatures like plastics
  • Substances which would contaminate the titration cell like coal dust, carbon black, etc.
  • Substances that are poorly soluble or insoluble such as cotton, paper, compressed wood, etc.

The ADP-611 features a modern microprocessor control ensuring maximum precision, reliability and user-friendliness: 

  • Easy method development: A patented scan mode automatically determines the optimal evaporation temperature based on the relation between released water and heating temperature.
  • Rapid rise and accurate control of the heating temperature.
  • Digital display of temperature and flow rate.
  • Automatic alarm if the set temperature cannot be reached within a certain time or if the temperature in the oven exceeds 350°C.
  • Serial interface which enables the evaporator to be remote controlled by the MKA-610 and MKC-610 Karl Fischer titrators.

To safely avoid contamination from atmospheric moisture the ADP-611 is equipped with a remote controlled motor driven magnetic bar to move the sample from the sample chamber into the oven.

The heating chamber is equipped with an electrically conductive transparent heater glass. This permits the sample condition to be monitored during the vaporization process.

The ADP-611 comes with two built-in desiccant tubes for the carrier gas. With an optional air pump, air instead of nitrogen can be used as carrier gas.
