L-128 Manual Nitrogen Blower Parameters

Laiheng manual 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, and judicial testing.

Laiheng manual nitrogen blowing 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.

Product advantages:

simple and convenient-----Pin design, easy to operate, time-saving and labor-saving

efficient-----Batch rapid completion of diversified product concentration, with visible concentration process

clean-----Blow needles are independent of each other, without cross contamination

energy saving-----The number of airways can be controlled according to demand to save nitrogen usage

Product Features:

√ Plug in design of nitrogen blower-----Suitable for sample concentration of small amounts in large 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;

The airflow regulation is simple, and 90 airway flow rates can be adjusted simultaneously to ensure consistent airflow size in each airway and improve concentration parallelism;

Nitrogen blowing is gentle and stable, while airflow blowing is as gentle as blowing air from the mouth. When concentrating trace samples, it prevents splashing and cross contamination caused by large airflow, reducing unnecessary loss of samples.

Separate design of constant temperature heating instrument and nitrogen blowing instrument-----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;

※ Wide temperature adjustment range, freely set from room temperature+5 ℃ -200 ℃, accurate heating and temperature controlThe accuracy control is ≤± 0.2 ℃, which can meet the heating temperature requirements of most experiments;
