Soap film flow meter 50mL 3001-11003 1 set

There is no unnecessary foaming to ensure accurate flow rate measurement, and the rubber does not become sticky because the liquid does not come into contact with the rubber. The top of the bottle has a bubble catcher so the bubbles won't spill out and make a mess of the surroundings. Maximum scale: 1.5mL Minimum scale: 0.5mL Accessories: Stand, special soap liquid, clip
