Water Bath Nitrogen Evaporator

Application range

ZKNEV Nitrogen Blowing Apparatus uses water bath constant temperature heating method to blow nitrogen gas into the heated sample surface quickly, continuously and controllably to concentrate the sample. This method is time-saving, convenient to operate and easy to control. It is mainly used for chromatography and mass spectrometry. It is widely used in the fields of pesticide residue analysis, environmental analysis, pharmaceutical drug inspection, biological analysis, commodity inspection, food and beverage, etc., by accelerating the volatilization of water, toluene, methanol, acetone and other solvents, saving time and effort , Rapid concentration to obtain samples.

Features

1 Support 12/24-bit channels to concentrate at the same time, easy and flexible to operate.

2. Each channel is equipped with a flow regulating valve with a dial as standard, which can realize the individual adjustment of the airflow of each channel. During the experiment, the lock can be pressed to prevent the flow from shifting.

3 Equipped with a lifting spring wheel assembly, the nitrogen blowing needle can be lifted up and down freely to meet the testing requirements of different heights.

4 Compatible with different test tubes, centrifuge tubes, small beakers and other concentrating tubes of various specifications and sizes.

5. The rotating sample holder can rotate 360 degrees freely, and the operator can touch the sample from the front, which is convenient for operation.

6. The flow rate adjustable digital display meter is used to display the precise flow rate in real time, which is convenient for quantitative control. The experimental data can be recorded and repeated.

7 Real-time display of water bath temperature, water bath heating adopts PID precise temperature control, with an accuracy of ±0.2°C.

8 The water bath will automatically cut off the power and give an alarm when the water bath is dry.
