Introduction

The kernel part of the holder is rubber sleeve treated by a new processing technique, which can resist HTHP and oils, acid, alkali and salt corrosion, has a long service life and can be replaced easily. In addition, the length of test core can be controlled within a certain extent. The holder has won the third prize of science and technology process award of the Ministry of Education in 1999.
