For general advice, see the instruction sheet for Finn Chambers on
Scanpor. You can fill the chambers in normal reading order by keeping the strips as shown in
figure. Fill in strips 1-2 (test substances 1-20). Turn the tray 180° and fill in strips 3-4 (test
substances 21-40). The middle area can be used for additional strips.
The tray may be marked e.g. by tape flags, which can be attached on the side of the tray.
Several trays can be stacked. Be careful not to push the bottom of a tray on the tapes or test
substances underneath. For a little higher distance between the trays turn every other tray 180°.
Cover the stack with an empty tray.
The tray is made of polyethylene terephthalate (PET).
