Wheaton Unispense MINI 2mm Peristaltic Pump Liquid Dispenser - TESTED!
Web Information
INTRODUCTION
The Unispense is a new generation liquid dispenser from Wheaton Science Products
(WSP) which features full microprocessor control of a wide range of dispensing
parameters. A full featured membrane keypad allows direct user entry of volume,
tubing size, automatic delay interval, and dose count. Additional user selective
functions include automatic/manual operation, memory functions, calibration, 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
easily replaceable silicone tubing assemblies available in 2, 3, 6, or 8 millimeter I.D.
sizes. Optional Viton tubing is available for dispensing organic solvents and strong
caustics. All WSP tubing is fully autoclavable.
Two versions, a mini and a standard pump head model, are available to
accommodate a wide range of laboratory and industrial filling procedures. The mini
pump head version offers a volume range of 0.20 to 150 mL per dose, while the
standard pump head version offers a volume range of 1.0 to 5000 mL per dose,
depending on tubing size utilized. 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 60 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 or the optional
footswitch for hands free operation.
The user can expect excellent accuracy and reproducibility as high as +/-1% at
midrange. Unlike conventional peristaltic pumps which rely on a "trial and error"
method of volume calibration, the Unispense allows direct user entry of volume in
milliliters. Up to 11 preselected set-ups can be stored in memory and quickly
retrieved for later use. Selections stored in memory are preserved even after
powering the unit down. An efficient cooling fan, and internal air flow arrangement,
provides optimum cooling for the heavy duty drive motor. The mini pump version
comes complete with two 2 mm silicone tubing assemblies, and the standard pump
version includes one each 3, and 6 mm silicone tubing assemblies. An optional
tubing support stand is available to facilitate hands free operation.
