CatLABS Tray Dish Siphon

The device uses a hydraulic siphon mechanism to create a continuous, controlled water exchange in your wash tray. By constantly replacing the water, it effectively draws out residual chemicals from the paper fibers, ensuring your prints are washed to archival standards without needing constant manual attention.

The CatLABS siphon is designed with versatility in mind. It includes both a conical soft rubber adapter and hard plastic connectors, which allow it to attach securely to most standard sink faucets, regardless of whether they are threaded or smooth-spouted.

Yes. The system allows you to manually adjust the flow rate, which is helpful for both maintaining the necessary water exchange for archival washing and conserving water during longer sessions.

The siphon is generally compatible with most standard darkroom print trays. Because it uses a flexible rubber hose, you have enough reach to position the intake and outflow points effectively, provided your tray is within a reasonable distance of your faucet.

No tools are required. The system is designed to be temporary and sink-mounted, meaning you can easily attach it when you are ready to wash prints and remove it once you are finished with your darkroom session.
