Fully Automatic Liquid Nitrogen Pump, ≤1 L/min and FTIR Compatibility (CAT#: STEM-BC-3917-ZJF)

The fully automatic liquid nitrogen pump is designed for timed and unattended cryogenic replenishment. It can supply liquid nitrogen to compatible Fourier-transform infrared spectrometer detectors. The system is suitable for use with specified Bruker and Shimadzu FTIR detector configurations. A plug-and-use refill design simplifies installation and routine operation. Users can preset filling intervals so that liquid nitrogen is delivered automatically to the detector. Installation requires no special tools and the unit is compatible with most FTIR detectors as stated. Low heat exchange with ambient air helps reduce liquid nitrogen evaporation during standby. The controlled flow minimizes splashing, vibration, noise, and unnecessary nitrogen loss. Automated transfer also prevents direct operator contact with liquid nitrogen and improves laboratory safety.
