This is the 304 stainless reservoir to attach the hsw unimatic. It holds and heats 50 ml of high viscosity fluids until they are thin enough to be used in the hsw unimatic. Compatible with the market standard filler device heat pads. There is a friction fit PTFE cap to help soothe fears of spillage.
The cf 50 reservoir works great for me for batches of 50-100. I will say, make sure to keep it clean. As well, be sure to not just leave it on the hsw, I did and now the dispenser that connects to the mondo line (if you upgrade) is stuck screwed in to the reservoir (user error, does not reflect on product quality). BUT if you have no intention of upgrading there is no reason to worry about removing that part except for cleaning. Absolutely a pleasure working with this product and looking forward to getting my upgraded setup running.
You can detach it using a very long flathead screwdriver and a heat gun. Gently heat the reservoir, and then unscrew the coupling using the slot located inside of the cf50 reservoir
