Description

Description

Automatic distillation and approved colorimetric titration for analysis of Kjeldahl nitrogen/protein, ammonium-nitrogen, TKN, Direct Distillation (DD), and volatile acids/bases.

Standard Features

  • Automatic distillation procedure includes sample dilution, alkali and receiver addition, distillation, titration, calculation, reporting and tube draining
  • Optional 20 or 60 place sample changer allows for fully unattended operation
  • Complete PC control of all registration and reporting through optional data management software
  • Alarms for reagent availability
  • Accurate bellow pumps; high-precision refillable, interchangeable burette
  • Intelligent cooling water control adjusts the flow according to temperature minimizing water consumption and costs
  • Distillate temperature sensor automatically shuts down unit if risk exists of inaccurate results
Design
  • Built-in variable steam generator for deionized or tap water
  • Alkali/water/receiver/waste tanks with level sensors
  • Surfaces exposed to reagents are made of corrosion-free, chemical-resistant dyed plastic materials
  • Self cleaning titration vessel

Safety Features

  • Sensors for: 1) tube in place, 2) automatic safety door, 3) reagent level, 4) water level and 5) overpressure for steam generator
  • SAfE™ (Steam Addition for Equilibration) technology improves safety by incorporating its own mixing procedure, reducing exothermic reaction between alkali and acid and making manual predilution of samples unnecessary
  • A fast tube draining system removes the need for handling hot reagents after distillation
  • Safety door and drip tray can both be easily removed for cleaning

Specifications

  • Analysis time: 3.5 min. at 30mg nitrogen (6.5 min. at 200mg nitrogen)
  • Distillation capacity: approximately 40mL/min
  • Measuring range: 0.1—200mg nitrogen
  • Reproducibility: ±1.0% relative (including the digestion step)
  • Recovery is greater than 99.5% at nitrogen levels between 1 and 200mg

Order Info

Dimensions: 48L x 58W x 69cm H. Net Weight: 77 1/4 lb. (35kg).

Compliance

Officially approved colorimetric titration system (AOAC, EPA, DIN, ISO) simplifies validation. GLP Routines are supported by Recovery Test process and documentation of all events during analysis.
