i have been kept a chloroform extract in an micro centrifuge tubes i have been observer a small change in shape of a lid. so I need to know a reaction mechanism between plastic and chloroform
It's not just about swelling. At the same time, there tends to be a substantial degree of permeation of the chloroform through the plastic (i.e. loss of solvent in your sample). If you can go for glass tubes, you're really on the safe side. The issue of permeation and swelling is also there for the lid which probably is going to be a plastics material in all cases. However, as it's gas phase transport only, the problem is much less severe.
Dear Gandham SANDEEP Kumar,that you describe is not a chemical reaction, it is simply the swelling of a polymer (probably polystyrene) after exposure to chloroform.

Chloroform attacks plastics, rubbers and coatings.

I would like to mix chloroform in a plastic cuvette. It eats away at the material. Is there something I could coat the plastic with to prevent this? Any suggestions would be helpful. Thanks!
