In order to request that a sample be analysed, you need to contact the staff responsible for the team.

You will need to give the toxicity and any storage precautions. Once the report has been delivered, if you do not collect the sample within one week, any remaining sample will be destroyed.

Optical microscopes are used to study thin specimens, since their depth of field is very limited. In general, they are used to examine crops, triturated preparations or a very fine sheet of any material. Normally depends on the light that pierces the sample from below and special techniques are usually needed to increase the image contrast.
