F M I LAB P U M P JR. (no motor) Model RHOCKCiO to 0.05 ml/stroke ModelRH1CKC:0to0.10ml/stroke
Model RH-B with DC Motor Drive (12 or 24 volt models)
$310 S310
If you want to pump those troublesome pid d l i n g l i t t l e s — l i k e f r o m 0.005 to 0.1 ml/stroke — we now have two pump head models that can solve your pumping prob lems. Both models feature positive displace ment valveless operation, are accurate to 0.1 % of flow range and are continuously ad justable even while running. Exceptional chemical resistance—fluids " s e e " only fluorocarbon and alumina ceramic—a fluid temperature tolerance of 250° F. and physical ruggedness make these pumps an ideal tool for handling laboratory fluids, in c l u d i n g suspensions, e m u l s i o n s , thin solvents and viscous concentrates.
V Model RHSY with AC Motor Drive
$380
Synchronous motor powered pumps. Each with its own RH miniature pump head and totally enclosed three-speed motor-drive assembly that gives a choice of 150. 300 or 600 piston strokes/min. Plug into standard 110-volt 60-Hz three-prong socket, are steplessly adjustable from zero to maximum flow and are reversible while operating. Flow rates to 34 and 60 ml/min at 600 SPM (depending on model).

The FMI RH miniature pump heads are di rectly coupled to the shaft of a high-quality totally enclosed DC motor. Pumps are adjust able by direct mechanical adjustment of flow rate through RH control ring or by remote con trol of supply voltage reaching the pump. Ex tension shaft accepts customer-supplied tachometer or other rotational instruments for remote process control.
