Storage

Sturdy blue cardboard box of about 13 x 13 x 5 cm, with a cardboard grid. It fits 100 test vials up to 2 ml. When filled with 2 ml vials, the lid rests on the vials, they stick out a little bit, which makes them easier to remove from the box. The grid is about 4 cm high and separates the vials almost entirely. Only the top part of the vial and the stopper are above it..

 

Sturdy blue cardboard box of about 13 x 13 x 5 cm, with a cardboard grid. It fits 100 test vials up to 2 ml. The grid is about 6,5 cm high, so the vials are completely separated from each other.  The drawback is that this makes it a little harder to get one out, though, so you may also want to consider the 5 cm high box. That one has a 3 cm high grid that makes it easier to access the vials.
