Title:
THIN TUBE CLEANING APPARATUS AND THIN TUBE CLEANING METHOD
Document Type and Number:
Japanese Patent JP2003053287
Kind Code:
A
Abstract:

To provide an apparatus and method for cleaning a thin tube whereby a thin tube having a smaller inner diameter, e.g. a sampling tube for NMR, can be efficiently cleaned without fail.

In order to clean a thin tube 50, a cleaning insertion tube 11 is inserted into the thin tube 50 and the thin tube 50 is covered with a cleaning external tube 12. The cleaning is done by causing water to flow simultaneously from the outside and inside of the thin tube 50, e.g. by switching a valve means. Methanol/acetone supplied from the outside of the thin tube 50 is caused to flow into the inside of the thin tube 50 by sucking with a cleaning insertion tube 11. Thus, a solvent flow can be formed simultaneously in the outside and inside of the thin tube 50, efficiently and rapidly cleaning it.
