The 77120-62 Masterflex Pump is discontinued.
Tubing available from Cole Parmer is shown in the last picture.
Can not close the Occlusion Bed Latch (The door that allows the tubing to be removed).  It's probably something simple, but I was not able to fix this.  No power adapter is included.  I did test this with another power adapter (not included) and this pump ran fine.  Just couldn't close the door.
This is sold as is.  No returns.

MORE ABOUT THIS ITEM
C/L® pumps are compact (1/4 DIN) and perfect for low-flow OEM use or analyzer applications. These easy-to-use, economical pumps feature reversible pumping, remote control capabilities, and rapid tubing changes. Ideal for consistent fluid delivery in chromatography, spectroscopy, and dispensing applications. These pumps feature self-priming which withstands minor back pressure.
Maximum suction lift of 5 ft (1.5 m); max discharge head of 20 ft (6.1 m); max pressure 15 psi (1.0 bar). Self-priming pumps withstand minor back pressure.
The MASTERFLEX C / L Pump Systems are small peristaltic pumps with integral drive motors and are intended for use with a series of tubing sizes that provide flow rates in the range of 2.2 µL / min to 37 mL / min. This pump system is designed to pump fluid through microbore tubing by means of peristaltic action at very low flow rates. It is ideal for sanitizers, reagent dispensing, analyzers, printing systems, controlled feeding and non-human infusion procedures. It is enclosed in a plastic 1/4 din case. The single-turn, adjustable speed control, provides variable flow operation. The green PWR On indicator lights whenever the pump is operating. The Power On / Direction Switch turns power on when either clockwise or counterclockwise pump rotor direction is selected. The MAX button is used for priming and purging and operates the pump at maximum speed while depressed. The rear panel contains a DC power input jack for connection of primary power and a 4-terminal barrier strip for connection of remote start / stop and for a DC backup supply.
