Specifications:
Characteristics	- microprocessor controlled - planetary drive with 8 actively driven stainless steel rollers - low pulsation - high repeatability on all channels - paint finished stainless steel housing
Tubing type	- 2-stop color-coded tubing, 0.13 – 3.17 mm i.d.
Tube-bed	- CA Click'n'go cassettes - simple handling - automatic occlusion setting - defined and reproducible occlusion conditions - each channel allows individual tubing selection
Operating panel	- 6-button membrane key-pad - LED display - MAX key for fast filling or emptying the tubing system
Operating modes	- pumping by speed (rpm) - stand-by mode — prevents tubing system from drying out - reversible rotation direction
Rotor speed	- 0.4 – 45.0 rpm (IP) - 0.11 – 11.25 rpm (IP-N)
Speed setting	- in rpm, resolution 0.1 rpm (IP) or 0.03 rpm (IP-N) - in %, resolution 0.1% (rpm)
Speed control	closed loop control for load independent speed
Analog input	Speed control (0–5 or 0–10V / 0–20 or 4–20mA)
Analog output	Speed monitoring (0–10VDC)
Digital inputs (TTL level)	Run/Stop, rotation direction, autostart
Differential pressure	1.0 bar (14.5 psi) possible (depending on tubing material); small tubing diameters and/or cassettes with pressure lever allow higher pressures
Motor type	DC motor
Power consumption	30 W
Power supply	115/230VAC; 50/60Hz
Protection rating	IP 30
Dimensions/Weight	see table above
Accessories	- cassettes - foot switch
