Raw Chemicals

RAW CHEMICALS

The listing on this page contains most of the raw chemicals used in commonly used formulae. Some chemicals not listed are possibly stocked or can be ordered. Some toxic chemicals, (such as mercury salts) we are unable to supply, or any chemical interpreted as being used for illegal activity (such as drug refining). Some chemicals cannot be sent outside the UK without special & expensive packaging and shipping.
The COSHH data sheet is available for each chemical and can be downloaded in PDF format by clicking the red COSHH button. These are each up to about 500k and could take a minute or two to download on a dial up connection.
