To:  Customers and Distributors of StainHD product range

It is our intention to change the Manufacturing Process of the products listed below.  The details of the change and the reason for it are given below.

If you have any difficulties or concerns accepting the change, please contact us immediately.

Product: StainHD product range (see list overleaf)

Proposed Change Date: From 1 March 2022

Change Details:

We are discontinuing some of the products and/or pack sizes from our current catalogue of StainHD products.

Reason for Change:

Due to the on-going Covid-19 pandemic TCS Biosciences continues to focus our production activities on our core products.

We have further reviewed our range of StainHD products and identified those products and pack sizes that are slower selling.

Some products will be discontinued from the range and some other products will have fewer pack sizes available than currently.  See list below


This change control is issued to give customers and distributors as much advance notice as possible prior to implementation of the change.

Until 1 March 2022 the products/pack sizes will continue to be available for sale while stocks last.

For your information, a certificate of analysis will be available for each product on our website https://www.tcsbiosciences.co.uk/dyesandstains/
