1. Introduction
Nutech 2100 is a system designed to clean SUMMA or silica coated
canisters or other air sampling containers (using canisters to represent
all those in all the following description). By repeatedly filling zero air
or other pure gases into the canisters followed by withdrawing air out
and keeping vacuum for a period of time the canisters canister will be
thoroughly cleaned. The device adopts programmable logic control
which enables to easily modify cleaning times, time limit, vacuum
control range and zero air-filling pressure control range
，
it is ideal for
cleaning smaller vessels and generating vacuum.
