Eluent delivery

The UHPLC Pump P 6.1L with LPG configuration has a new LPG valve for precise mixing efficiency of up to four eluents at up to 1000 bar. The integrated degasser prevents air bubbles in the system. A mixing chamber is mounted on each Pump P 6.1L. This can be adapted to the respective application as required.

Sample Injection

The Autosampler 6.1L can inject 0.1 – 5000 µl to have a large flexibility. Using standard vials or two microtiter plates will give you a maximum sample capacity of up to 768 samples or 108 vials. The UHPLC version can be used up to 1240 bar system backpressure.

Column thermostating

The Column thermostat CT 2.1 is suitable for column thermostatization above and below room temperature. The instrument operates with a microprocessor controlled Peltier element for exact temperature settings.

Chromatography data system

KNAUER ClarityChrom® is a powerful, yet easy-to-use chromatography software for instrument control, data acquisition and data processing. It is an economical solution compared to other more complex chromatography software while still offering FDA 21 CFR Part 11 compliance.


The diode array detector DAD 6.1L covers all conceivable applications with a spectral range of 190-1000 nm. With its novel light path and optimized flow cells, it is one of the most powerful devices on the market.

This AZURA Analytical system can be customized with several detectors

  • The detector DAD 2.1L features a novel light path and flow cell architecture with improved handling and excellent performance. This Diode array detector can be used in the wavelength range of 190-700 nm.
  • The detector MWD 2.1L is an 8 channel, sensitive multiwavelength detector combining high performance with easy handling at an affordable price.This multiwavelength detector detector can be used in the wavelength range of 190-700 nm.
  • The variable single wavelength UV/VIS detector UVD 2.1L comes with an installed deuterium lamp which covers a wavelength range from 190 to 750 nm. It is a competitively priced detector for routine HPLC applications including fast LC methods.
