KT 200 Kjeltec

The KT 200 Kjeltec™ Distillation unit provides a simple and reliable solution for safe and semi-automatic distillation for protein determination. The possibility to pre-program alkali addition and distillation time supports the production of accurate results independent of operator.

KT 200 Kjeltec

Overview

Value

Simple, safe and reliable analysis according to official standards for accurate results independent of operator.

Sample Type

Food, Feed, Feed ingredients, Forage, Pet food, Grain, Cereal, Oil seeds, Meat, Meat products, Milk, Dairy products, Beer and Beer ingredients

Parameters

Nitrogen, Protein, Non Protein Nitrogen (NPN), Volatiles (SO2, TVBN and more)

Features

SAfE
SAfE

The patented SAfE* technology improves safety by a mixing procedure, reducing the exothermic reaction between alkali and acid during distillation and removing the need for manual pre-dilution. *Steam Addition for Equilibration

Autosamplers
Autosamplers

An optional 20 or 60 place Autosampler provides the benefits of automation even at lower sample throughputs. Just load your sample racks directly from the digestion block and KjeltecTM will perform accurate analysis unattended for more than four hours.

Safety Features
Safety Features

A fast tube draining system removes the need for handling hot reagents after distillation. Interlocked safety door which must be closed with a tube in place before the unit will operate. Cooling water flow is controlled automatically and a temperature sensor stops the unit if the distillate is too hot. Sensors monitor tube in place, safety doors, reagent levels, water level and over-pressure in the steam generator providing safe use.

Unmatched Accuracy
Unmatched Accuracy

The superior performance of a Kjeltec titration system is based on colorimetric measurement of a precise chemical reaction for end-point detection. Accuracy is assured time after time with the additional benefits of long-term stability, wide working range, speed and simplicity without the need for repeated and costly calibration procedures.

Models

The Kjeltec™ series consists of four models: Kjeltec™ 8100, 8200 and 8400 and KT 200 Kjeltec™ with different levels of automation.
