GPS® Dishware has improved safety (no droplet collapsing or mixing) and better pH control. The GPS® microwells protect against sudden movements and the raised lid promotes gas exchange, prevents contamination, and stops oil seals from forming. They are made of non-toxic medical grade, non-pyrogenic polystyrene and have better ergonomics than a 35 mm dish. GPS® Dishware are CE and ISO Certified, and 1-cell MEA and
Endotoxin (LAL) tested.
