                                  Tristel plc

                               Acquisition update


Tristel plc ('Tristel'), the healthcare business which uses its proprietary
chlorine dioxide chemistry for infection control in hospitals, in water
treatment and the food processing industry, reports that the integration of
Tristel Technologies Limited ('TTL') (previously Vernagene Limited) is making
good progress and that the performance of the business is in line with
management expectations.

TTL, the chlorine dioxide specialist focusing on water treatment and
contamination control in food processing, was acquired on 5th June 2006 at a
cost of £1,000,000, funded by cash of £800,000 and a £200,000 loan provided by
one of Tristel's shareholders.

Progress made with the TTL business and in Tristel's core activities in the
hospital marketplace will enable Tristel to repay early the £200,000 loan from
internally generated cash flow.  It is expected that the loan will be repaid
during August 2006.

TTL will make a positive contribution to Tristel's results for the year ended
30th June 2006 which are expected to be announced in October.
