What should I do if I need a lab dry glove box but there is no nitrogen or argon gas source? Today, I will introduce a glove box with a humidity control module. There is a black control module on the back of this lab glove box. The left side is the temperature display, which cannot be controlled. The right side is the humidity, which can be adjusted by the up and down keys. The humidity can be as low as 1%RH. It can be used directly by connecting a 220V power supply. This humidity control module can be installed on all other types of acrylic lab glove boxes.
