The Alvetex Well Insert Holder and Deep Petri Dish enables users to grow their 3D cultures in larger volumes of media compared to an ordinary multiwell plate, facilitating fewer media changes. Capable of sustaining long term 3D culture experiments (3-4 weeks).

The well insert can be positioned at three different levels in the insert holder: high, medium and low. This feature allows cultures to be raised to the air liquid interface by moving the insert to a different level within the same holder.

Positioning the well inserts at different levels may also be used to conserve expensive media or allow for increasing media volumes for demanding cell types over the course of a long term experiment.
