Laboratory Nitrogen Sample Concentrator Concentration with LED Display

The nitrogen sample concentrator NDK200-2N is mainly used for concentrating or preparing sample
in batch. Such as drug screening, hormone analysis, liquid phase and mass spectrometry in the
analysis of sample preparation. It works by blowing nitrogen in the surface of sample which is being
heated to accelerate evaporating and separating the solvent in the samples without oxygen.
Instead of the rotary evaporation instrument, nitrogen sample concentrator can efficiently
concentrate dozens of samples simultaneously.
  • T/T

  • CE


1. The height of the air chamber plate can be adjusted. The length of a standard gas needle

is 150mm.

2. LED displays immediate temperature and diminishing time. Operation is simple and convenient.

3. Built in overheat protection, automatic fault detection and fault beep alarm devices.

4. The entire equipment can be put into ventilation cabinet when the concentration sample is in

toxic solvents.

5. Synchronously working with heating by dry bath in the bottom and nitrogen blowing on the

surface accelerates liquid evaporation and sample concentration.

6. Unique patented design for air channel control system, enhances air tightness and reduces

 potential leakage; easy to operate, lift/press air needle to realize channel 

switch; the switching

status of each channel is clear at a glance.

7. Standard configured air cavity and adjustable bracket.
