Saw the reactor mentioned in the thread..

But it cannot fit my 16/22mm hose, so I decided to DIY my own to my own requirement to suit my equipment layout in my cabinet. Made this slightly longer to avoid CO2 from escaping to the outlet.. can also make the transparent one.. but must make around 27 pieces because the min-order-qty to buy the 50mm transparent tubing is 3m. Price-wise is not much different from this white-body reactor. Also another option is to use the snap-on module for the CO2 inlet. Pls see my posting of buy-&-sell to the module.

To drill the openings is quite siong without the proper tool..








I got another one for sale because the straight inlet and outlet is not suitable for my usage and setup. Made this before sourcing the angled-inlet and outlet. If you are interested pls refer to the following thread.
