Disposal
Dispose of the EXT70/70/200H Turbomolecular Pump and any components and accessories safely in accordance with
all local and national safety and environmental requirements.
Note that the pump chamber is treated with Alocrom 1000, which is a chromate conversion coating with a thickness
of < 1 micron. The total weight of the coating on the chamber is approximately 20 mg.
Particular care must be taken with any components which have been contaminated with dangerous process
substances.
Take appropriate action to avoid inhalation of any particulates that may be present in the pump.

event, use appropriate personal protective equipment when handling and disposing of the pump,
and ensure that all pump inlets and outlets are capped off before disposal.
