Dennerle Replacement Membranes and Dosing Rings for Dosator

This package of replacement Dosing Rings and Membranes for the Dosator from Dennerle is enough to keep your Dosator going for 6 months! One would have to buy quite a few of these before approaching the price of a dedicated electric dosing pump, but said pump will never rival the convenience of the Dosator! Pack includes 6 membranes and six sets of dosing rings.
