The NNB (LNB) nitrogen evaporator, developed by Shanghai Xinzhuang Instrument Co., Ltd., is an energy-efficient and environmentally friendly device that stands at the forefront of domestic technology. As a professional company specializing in research, development, production, sales, and service of scientific instruments, we offer a wide range of products, including nitrogen evaporators, water bath nitrogen evaporators, visible nitrogen evaporators, low-temperature constant temperature systems, shakers, incubators, and more.

Our nitrogen evaporators utilize purging and trapping technology, using inert nitrogen gas to efficiently and continuously blow over the sample surface. This process helps achieve rapid separation, purification, and anaerobic concentration of complex samples. It's a fast, convenient, and accurate method that saves time and improves efficiency in laboratory settings.

Visible nitrogen evaporators are especially useful for processing large volumes of samples in applications such as drug screening, hormone analysis, liquid chromatography, and mass spectrometry sample preparation.

Key features of our visible nitrogen evaporator include:

  • Heating system allows quick and efficient heating of the sample to evaporation temperature.
  • Each purge needle can be independently controlled, with adjustable flow rates to save gas and adapt to different test tubes.
  • Gas needle positions can be adjusted to fit various tube sizes, with a standard length of 150mm.
  • Adjustable air chamber height for flexibility during use.
  • Allows real-time observation of the sample during concentration.
  • Can be placed inside a fume hood when working with toxic solvents.
  • Includes automatic fault detection and alarm system.
  • Equipped with a standard air chamber and adjustable bracket for stability.
  • Built-in over-temperature protection ensures safety.
  • Features LED display for real-time temperature and time monitoring.

Performance specifications include:

  • Temperature range: 5°C above ambient to 150°C
  • Heating time: ≤ 30 minutes (from 40°C to 150°C)
  • Temperature accuracy: ±1°C between 40–100°C, ±1.5°C between 100–150°C
  • Temperature stability: ±1°C at 100°C
  • Single module design
  • Display precision: 0.1°C
  • Maximum time setting: 99 hours 59 minutes
  • Nitrogen flow rate: 0–10 L/min
