Premium Diagnostic & Chemical Supplies

The Avonchem name has existed for over 50 years; it’s a proud family business with a long history in supplying the pharma and manufacturing industries.

Originally our product portfolio focussed on chemicals, buffers, solvents and reagents but over the last 10 years we have added an extensive range of diagnostic tests to our catalogue; used to indicate a range of underlying health conditions.

We now have a number of prestigious clients in the healthcare industry including NGOs and their feeder suppliers.

From our base in Macclesfield and through a network of long standing manufacturers and importers, we are able to supply over 3,000 product lines. Led by CEO James Gray with his extensive knowledge of the life sciences, healthcare and biotechnology industries we are certain that we can meet each client’s individual needs.
