The use of non pipeline ventilation cabinet, can only use restricted chemicals. Different manufacturers, restricted chemicals also have distinction. This is why should carefully check each manufacturer defined chemical list. For example:, no tube filtration technology leader erlab group, the limited use of chemicals has 600.
