Scharlau Petri dishes are manufactured in high transparency PS following a fully automated process with strict quality controls, giving them the strength and transparency ideal for microbiological applications. Their great mechanical resistance makes them non-deformable. The dishes with winds facilitate the circulation of the air and avoid the possible condensation. Aseptically produced in 'Cleanroom ISO 6' rooms, a level of sterility is guaranteed. In addition, sterile dishes are sterilised by radiation. They have a ring to facilitate and improve stability once stacked.
