At the back of the Panlab Organ Bath systems there is an inlet port for each chamber for buffer solution and a single port for overflow and water bath drain. You will need tubing at appropriate length with following diameter:
Inflow for tissue buffer solution: ID 6 mm, OD 8 mm
Outflow for drain: ID 8 mm, OD 12 mm
Note: when filling the chambers from one reservoir you should also have enough "Y" or "T" tubing connectors.
