When to choose it

This tank ships with two adjustable spirals for 35mm or 120 roll-film workflows. It fits a bench where you plan to agitate the film with the tank upright and can confirm the required liquid volume for your batch.

The listing specifically warns that the red cap will not seal for inversion. Follow that operating limit even though a separate bullet calls the tank watertight.
