Chemical Storage: Hi There, Thank you for putting together a great website.
laser classification: We have not been using our old laser because it was a Class 3B, and therefore banned in secondary schools under the older code of practice.
Genetics: Looking at ordering some PTC papers and a MSDS is not supplied with the papers. Are we still allowed to purchase them and do the experiment? Many thanks.
