The KjelFlex
The KjelFlex K-360 is a highly modular system with integrated boric acid, sodium hydroxide, and water pump, electronic steam regulation, connections for an external titrator for automatic determination and an acid resistant pump for Non-Kjeldahl applications. The K-370 is the most convenient solution available for labs with a large sample throughput. The K-370’s multitasking software enables you to simultaneously carry out measurements, prepare new measurements or print out results and is optionally working with the Autosampler K-371.

K-360: Highly flexible distillation unit with possibility to connect an external titrator

K-360 as stand-alone instrument provides

  • The sample tube is emptied automatically after distillation
  • All internal and external components are easily accessed from the front
  • Automatic dosing of boric acid, sodium hydroxide and water
  • Acid-resistant pump for non-Kjeldahl applications available as an option
  • The steam output is continuously regulated from 30 to 100%
  • Memory capacity for 50 specific methods and 500 determinations
  • Cost-optimized design: two variants are available. Ideally adaptable to your applications
  • The software supports routine GLP functions such as password protection, Results memory (ml consumption) etc.

K-360 combined with a titrator

  • By connecting an external titrator, the K-360 is expanded to form a semi-auto-matic nitrogen and protein determination unit in accordance with Kjeldahl. This configuration gives you the following advantages:
  • Time saving due to automatic titration start and automatic aspiration of the sample and receiver solutions after titration
  • Integrated solution due to transfer of the titrant consumption to the K-360
  • Processes samples efficiently: The determination is started at the press of a button. The subsequent steps are fully automatic without the interaction of the user. All parameters are stored in the methods saved.

K-370: Compact high-end distillation unit with integrated titrator

  • The K-370 is the most convenient solution available for precise analysis in Kjeldahl labs handling large sample numbers. Featuring a high-performance steam generator, an integrated titration system and multitasking software, the K-370 is a fully-automatic system designed for the most demanding users. The K-370 sets new standards of safety, guarantees accurate measurement results, offers an upgrade option to include an autosampler. The K-370 allows you to work in accordance with official methods such as AOAC, EPA, DIN, etc.
  • Compact stand-alone unit with modern, functional design
  • Easy-to-read control panel with integrated keyboard
  • High-resolution, high-contrast color display
  • Leading-edge, high-performance software for easy operation
  • Numerous safety features such as protective door, sample tube detector, cooling water flow sensor, drip tray, system for automatic emptying of sample tube and receiving vessel, automatic self-test
  • Electronic regulation of steam output
  • Option of automated sample changing in combination with Kjeldahl Sampler K-371

Kjeldahl Sampler K-371

  • The sampler features an innovative samplechanging mechanism that uses steam to transfer samples to the distillation unit. Carefully selected materials and numerous safety features (such as acrylic glass safety shield (locked during process), sample tube and collision detection system ensure optimum protection for users and the environment
  • Rack with space for 20 sample tubes, compatible with Digest System K-437 and Digest Automat K-438
  • Express rack with space for 4 sample tubes
  • Enables both automatic and manual operation by simply changing the software parameter
