The FR-50/FR-55S is a convenient tool to adjust both solution flow rates and vacuum pressure in a variety of applications.

Solution flow is adjustable from zero to a maximum of 10 mL/min (measured with a solution head of 30 cm) and the units have calibrated adjustment rings to permit returning to a predetermined setting.

The FR-55S includes a convenient on-off switch for interrupting the flow without disturbing any settings.

Both holders are compatible with the In-line Solution Heater Holders which can provide a secure footing for either the FR-55 or FR-55S.
