L-148 Laiheng Automatic Nitrogen Blowing Instrument

Principle of nitrogen blowing concentration:

By blowing nitrogen into the surface of the heated sample, the moisture in the sample is rapidly evaporated and separated, thereby achieving the purpose of sample concentration. The nitrogen blower can concentrate multiple samples simultaneously and maintain their purity, making it an important tool for sample pretreatment.

Application scope:The pre-treatment of experimental samples is widely used in the analysis fields of pesticide residues, food additives, biochemistry, medicine, judicial testing, etc.

Lai Heng L-148 Automatic Nitrogen Blowout InstrumentSuitable for concentration of large quantities of samples, such as drug screening, hormone analysis, liquid phase, gas phase, and sample preparation in mass spectrometry analysis.

Lai Heng L-148 Automatic Nitrogen Blowout InstrumentProduct Features:

Shah user-friendly design-----Efficient, convenient, and safe completion of sample pretreatment

※ Time program control, nitrogen blowing needle automatically tracks the liquid level, buzzer alarm reminder after concentration is completed, no manual supervision required;

Equipped with a gas flow meter, the flow regulation is simple and the airflow control is stable;

6 sets of LED lighting devices are clear and bright, making it easy to observe the liquid level position of concentrated samples;

※ Equipped with a powerful exhaust system, it can directionally discharge evaporated exhaust gas, reducing the harm of exhaust gas to operators.

Shah Pin type design-----Suitable for concentration of large and trace samples

Quick installation of blowing needles, 90 blowing needles do not require manual knobs one by one, can be inserted into the air chamber to complete the installation;

※ It can adjust the flow rate of 90 airways simultaneously, ensuring consistent airflow in each airway and improving the parallelism of sample concentration;

※ * Airway distribution method, airflow blowing is as gentle as blowing air from the mouth, preventing splashing and cross contamination caused by large airflow during concentration of trace samples, and reducing unnecessary loss of samples;

The nitrogen blowing needles are independent of each other and have no cross contamination.

Shah split-type design-----Improve the efficiency of using a constant temperature heating device

The constant temperature heater can be used alone or in combination with a nitrogen blower or other instruments to save experimental costs;
