Used Lab Equipment

Features:

The EM range of oil-sealed rotary pumps is renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and the ability to withstand vapour. They are commonly used for laboratory and light industrial applications. It is a freestanding instrument with the drive provided through a flexible coupling by either a single phase or three phase motor.
