Nitrogen Analyzer
NANBEI Is Professional On Providing One-step Solution Of Laboratory Instruments And Equipment
Product Numbers: NDK200-1A
Product description:
The nitrogen sample concentrator (96-gas-needles) NDK200-1A 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.
Product features
1. The heater allows samples to be heated rapidly to the evaporation temperature, through the gas blow to the solution surface via needle at the same time, prompting rapid evaporation and concentration solution.
2. The gas chamber height can be adjusted, the length of standard gas needle is .
3. Each blow needle can be controlled independently, can be blown, separate flow regulation, no waste of gas.
4. The entire system can be arranged in the ventilation cabinet when process concentration of toxic solvents,
5. Built in over-temperature protection device, automatic fault detection and alarm function.
6. LED display, temperature and time diminishing display, the operation is simple and convenient.
7. configured standard gas chamber and special adjustable bracket.
