Hardy, long-lasting, and crack-resistant, vacuum tubing can handle virtually all inorganic chemicals found in the lab. It is non-oxidizing and non-contaminating. This material can withstand a vacuum at room temperature, and will hold up under corrosive atmospheres. It is flexible and crystal clear, and this clarity allows for monitoring of possible backups. The glassy-smooth interior helps prevent build-up so that cleaning is easy and quick, and it is less permeable than regular rubber tubing.
