Shanghai Xinzhuang Instrument Co., Ltd. is a leading manufacturer in the field of scientific laboratory equipment, known for its NNB (LNB) brand nitrogen evaporator. As a professional enterprise engaged in R&D, production, sales, and service of scientific instruments, the company has established itself as a pioneer in energy-efficient and environmentally friendly technology. Their product line includes nitrogen blowers, water bath nitrogen evaporators, visible nitrogen evaporators, low-temperature constant temperature devices, shakers, incubators, and more.
The nitrogen blowing instrument developed by Shanghai Xinzhuang utilizes purging and trapping technology, where inert nitrogen gas is applied to the surface of the sample in a controlled and continuous manner. This process effectively removes solvents, enabling quick separation, purification, and anaerobic concentration of complex samples. The method is not only time-saving but also highly accurate and user-friendly.
The visible nitrogen evaporator is particularly useful for preparing large volumes of samples, commonly used in drug screening, hormone analysis, liquid chromatography, and mass spectrometry sample preparation. It features a high-efficiency heater that rapidly brings the sample to evaporation temperature. Nitrogen gas is delivered through a gas needle into the solution, accelerating evaporation and concentrating the sample efficiently.
Each gas needle can be independently controlled, allowing for individual purging and flow adjustment, which minimizes gas waste. The position of the gas needles in the air chamber is adjustable, making it compatible with various test tubes. The standard gas needle length is 150mm, and the height of the air chamber is also adjustable for optimal performance.
One of the unique features of this device is the ability to monitor the liquid level of the concentrated sample at any time during the process, ensuring greater control and precision. With its advanced design and user-friendly interface, the NNB (LNB) nitrogen blowing instrument has become a preferred choice among laboratories across China.
Shanghai Xinzhuang Instrument Co., Ltd. continues to innovate and improve its products, maintaining its position as a leader in the domestic market. Their commitment to quality, efficiency, and environmental responsibility ensures that their instruments meet the highest standards in scientific research.
