INTRODUCTION

The Omnispense Plus® is the latest generation liquid dispenser from Wheaton Science Products (WSP) which features full microprocessor control of a wide Tange of dispensing parameters. A full featured membrane keypad allows direct user entry of volume, tubing size, automatic delay interval, ramp time, pump direction, pump speed, pump function and dose count. Additional user selective functions include calibration, automatic / manual operation, memory functions and audible cycle alert. The self-prompting LCD screen and one-step volume calibration ensures quick setup and ease of operation. The pump is self-priming and uses a wide variety of tubing materials and sizes.

An adjustable ramp feature allows the pump to come up to speed gradually and helps prevent foaming or splashing when dispensing into dishes or small vials. For added versatility, the user can select between automatic or manual modes. When operated in the automatic mode, an adjustable delay can be set from 0.5 to 25.5 seconds between doses to accommodate user dexterity and work load. When operated in the manual mode, the dispenser can be activated by depressing either the front panel mounted start key, the hand set mounted start key, or the optional footswitch for hands free operation.

Unlike conventional peristaltic pumps which rely an a Irial and error" method of volume calibration, the Omnispense Plus® allows direct user entry of volume in milliliters. Up to 100 pre-selected set-ups can be stored in memory and quickly retrieved for later use. Selections stored in memory are preserved even alter powering the unit down. Pump speed is variable from 41 to 417 rpm, which facilitates usage where flow rate control is critical. A flexible tubing support stand is included to facilitate hands free operation.

The Omnispense Plus® can be used in both laboratory and industrial settings. The pump can be triggered to Tun remotely either by the optional footswitch, or by an industrial Programmable Logic Controller (PLC) using either a dry contact relay or isolated open collector transistor Output. The Omnispense Plus® is capable of sending an End of Dispense (EOD) feedback signal to a Controller for remote automated operation.
