4.0 Introduction
The UniSpense® PRO is the latest generation liquid dispenser from WHEATON Industries, Inc., which
features precision microprocessor control of a wide range of dispensing parameters.
4.1 The Peristaltic Pump Process
Fluid is contained within a flexible tube, which is placed in the precision pump head. The center rotor, with
a number of rollers, compresses the flexible tube. As the rotor turns, the part of tube under compression
closes and forces the fluid to be pumped to move through the tube. After the roller passes, the tube
opens to its natural state and fluid flow is induced to the tubing. This process is called peristalsis. The
pump has no contact with the fluid being transferred.

5.1 Control
The UniSpense® PRO can be used in both laboratory and industrial settings. In addition to the front-panel
keypad, the pump can be triggered to run remotely either by the optional footswitch, or by a dry contact
relay or isolated open collector transistor output as part of a more advanced automated dispensing
system. The UniSpense® PRO is capable of sending an End of Dispense (EOD) feedback signal to a
controller for remote automated operation.
5.2 User Interface
A chemical resistant 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, memory functions and audible cycle alert. The self-prompting, symbolic LCD
screen ensures quick setup and ease of operation.
5.3 Performance Highlights
An adjustable delay can be set from 0.5 to 99.9 seconds between doses to accommodate user dexterity
and work load. The pump can be activated by depressing either the front panel mounted start key, or the
optional footswitch for hands-free operation.
Up to 9 pre-selected 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. Pump speed is selectable at 75 and
150 RPM. A flexible tubing support stand is included to facilitate hands-free operation.
6.0 Installation
Install the unit where there will be adequate room for the unit to operate. Provide enough clearance
around the unit to keep items away from the rotating pumps and tubing.
6.1 Input Power Requirements
This equipment is designed to operate from a 100-240V single-phase AC power source at 47 to 63 Hz.
The line voltage / fuse label located on the lower rear of the unit shows the nominal input voltage set for
the unit at the factory.
6.2 Power Cord Set
This unit has been shipped from the factory with a power line cord that has a plug appropriate for your
area. If the wrong power cord has been shipped for your particular application, contact your nearest
WHEATON Industries dealer for the proper cord. The UniSpense® PRO has been equipped with a 3-wire
grounding type power cord. The unit is only grounded when it is plugged into an appropriate receptacle.
Do not operate the unit without adequate grounding protection.
7.0 Initial Startup and Operation
CAUTION: Keep hands and fingers away from rotating parts of the machine. Make sure
tubing is secured and clamped properly before running pump. Pump should be turned off
and unplugged while loading tubing into pump head.

7.1 Pump Head Attachment and Tubing Installation
Pump Head Setup - Raise the cover on the pump head so that the
arrow (upper left) points to the mark on the pump frame. Identify the
tubing bore diameter from the tubing manufacturer’s packaging. Using
the graduations on the side of the head, adjust the tubing clamps on
both sides via the thumbscrews at the bottom of the pump head to the
proper tubing bore size.
Pump Head Attachment - Align the pump drive shaft tang with the
drive rotor slot on the back of the head. Align the slots on the back of
the head with the ears on the pump head mounting plate. Place the
pump head on the mounting plate and twist the pump head clockwise
until it clicks into place.
Tubing Installation – Insert Tubing into the pump head between the
pump head cover and the rollers. The dispensing end should be
located to the right. Close the pump head cover to secure the tubing.
Make sure tubing is not twisted and has no kinks.
WHEATON UniSpense® PRO Peristaltic Pump
CAUTION! Improper adjustment of the tubing clamps may
result in improper performance of tubing, or premature wear and
failure of tubing. DOUBLE CHECK clamp settings before
proceeding.
To Remove Pump Head – Press the release tab at the lower right of
the pump head. While holding the release tab, rotate the pump head
counterclockwise and pull off.
7.2 Tubing Characteristics
Silicone tubing exhibits a wide range of chemical resistivity and should be suitable for most general
dispensing applications. However, there are a few organic substances which cannot be dispensed
accurately due to their effects on silicone tubing. These substances include hydrocarbons, acids and
halogenated hydrocarbons. To determine if a particular tubing-chemical combination is compatible,
immerse a 100mm length of tubing in the chemical in question for 72 hours at room temperature. If after
this time period the tubing has increased or decreased in length by less than 3%, the combination is
compatible. Length changes of 3% to 8% are worth trying, but will not produce the most accurate results.
Changes in length over 8% are considered to be unsatisfactory. It should also be noted that a new tubing
assembly may cause slight filling variations for the first one to two hours of operation.

WHEATON UniSpense® PRO Peristaltic Pump
13.0 Tips on Obtaining Maximum Accuracy
Several operating variables must be considered in obtaining maximum dispense accuracy, such as tubing
sizes, and pump speed. In addition other variables such as tubing characteristics (material, age, chemical
compatibility) and pumped – medium characteristics (viscosity, chemical makeup, temperature) must also
be considered in obtaining best dispensing results.
Proper Tubing Selection
Each different tubing size will provide a different liquid delivery range when used in conjunction with the
pump unit. Accuracy is increased as the number of pump head revolutions required per dispense is
increased. Tubing size should be selected so the pump head makes at least 3 complete revolutions.
14.0 Maintenance and Troubleshooting
DANGER! NEVER ATTEMPT TO PERFORM REPAIRS IF THIS INSTRUMENT IS
PLUGGED IN! TO AVOID SERIOUS ELECTRIC SHOCK OR ELECTROCUTION, THIS
INSTRUMENT MUST BE DISCONNECTED FROM THE SOURCE OF AC POWER
BEFORE REMOVAL OF ANY PROTECTIVE COVERS.
14.1 Maintenance
Routine user maintenance should include a regular inspection of the tubing assembly for excessive wear
and leaks. Many service problems can often be cured by simply replacing a worn tubing assembly. To
insure high accuracy, the pump rotor and tubing clamping mechanics of the pump head should be kept as
clean as possible at all times.
The unit cabinetry has been designed to an IP31 rating. The plastic top is mineral filled polypropylene and
the base is painted cast aluminum. The pump head and outer cabinet may be wiped down with warm
water and any mild household cleaning solution. Never use abrasive cleaners or strong acids as cleaning
solutions. Never place liquid containers on top of the UniSpense® PRO, as a spill could result in liquid
entering the dispenser. If liquid should accidentally contact the front panel, the unit should be
disconnected from the AC power source immediately and carefully dried with towels and warm air.
Although the UniSpense® PRO is designed for easy service, it is highly recommended that the instrument
be returned to WHEATON Industries should any major repairs be needed.
Pump rollers can be occasionally lubricated with Teflon lubricating oil.
