Here’s a bulk pack – 100 empty aluminum cartridges, sized 25.
5mm diameter by 45mm long, perfect for dispensing flexible acrylic materials in dental labs.
These are fresh, unused, and ready to fill with your favorite impression material or temporary crown resin.
Made in China, but they’re well-formed, smooth inside, and seal nicely with standard plungers.

These cartridges are a staple for dentists and lab techs who work with flexible acrylics, soft liners, or even some composites.
The aluminum body is lightweight but sturdy enough to handle hand mixing or extrusion guns.
No rust, no dents – they come clean and dry, so you can load them up without contamination worries.

They’re unbranded and generic, but that’s actually a plus – you’re not paying for a fancy label, just the raw cartridge that does the job.
The dimensions match most common flexible acrylic systems, and the 45mm length gives you a decent working volume without being too bulky.
Perfect for chairside or bench use.

UPC is included for inventory tracking, but honestly, you just need these to work.
And they do.
