Please Note: These cartridges have been recently re-designed to work with a 50ml square-back cartridge dispenser, even though they are actually 41.5ml (1.4 oz) in volume. This 3M cartridge will fit into dispensers such as the MedMix DMA50 dispenser. It is strongly advised that you use a 50ml Dispenser for this cartridge.

If you do not have one one of these dispensers, please check out some of the other product options to the right. We do sell this as a kit with an included Dispenser.
