Trading update and results date

Tristel plc (AIM: TSTL), the manufacturer of infection control, contamination control and hygiene products, provides a trading update ahead of the publication of its preliminary results for the year to 30 June 2011.

Since the Licence Delays and Trading Update announcement of 28 April 2011, Tristel has now secured the licence to sell the Stella decontamination system in China and the VAH listing for the Wipes System in Germany.

In the final quarter of the financial year, ended 30 June 2011, sales in Germany have increased significantly each month in percentage terms and sales of the Crystel products, sold into the pharmaceutical and personal care market, have commenced. In June 2011, 30 Stella System upgrades were also sold to our Chinese distributor network.

The Board is pleased to report that it now anticipates pre-tax profit (before share based payments) will be greater than £500,000, exceeding its expectations at the time of the April announcement. The Company continues to pursue its expansion plan and remains debt free.

A preliminary announcement of results for the year ended 30 June 2011 will be made on Monday 24 October 2011.
