product. Please also register your product with BioTek to ensure that you receive
important information and updates about the product(s) you have purchased.
You can register online through BioTek’s Customer Resource Center (CRC) at
www.biotek.com or by calling 888-451-5171 or 802-655-4740.
Cassette Warranty
MicroFlo Select dispense cassettes are backed by BioTek's Confidence-Plus lifetime
warranty. For the lifetime of the cassette, BioTek guarantees the cassette components
(Tip Holder, Center Holder, Tube Tensioner, and Tube Organizer) will withstand
steam autoclave conditions of 121°C and 1 bar (750 mmHg) without adversely affecting
dispense performance. In the event of a failure of any cassette component previously
listed, BioTek will replace the cassette components free of charge.
Warnings
Operate the instrument on a flat surface away from excessive humidity.
When operated in a safe environment according to the instructions in this
document, there are no known hazards associated with the instrument. However,
the operator should be aware of certain situations that could result in serious
injury; these vary depending on the instrument type. See Hazards and
Precautions.
Hazards
The following hazards are provided to help avoid injury:
Warning! Power Rating. The instrument’s power supply or power cord must
be connected to a power receptacle that provides voltage and current within the
specified rating for the system. Use of an incompatible power receptacle may
produce electrical shock and fire hazards.
Warning! Electrical Grounding. Never use a two-prong plug adapter to
connect primary power to the external power supply. Use of a two-prong adapter
disconnects the utility ground, creating a severe shock hazard. Always connect the
power cord directly to an appropriate receptacle with a functional ground.

Precautions | xi
MicroFlo Select Operator's Manual
Warning! Internal Voltage. Always turn off the power switch and unplug the
power supply before cleaning the outer surface of the instrument.
Warning! Potential Biohazards. Some assays or specimens may pose a
biohazard. Adequate safety precautions should be taken as outlined in the assay’s
package insert. This hazard is noted by the symbol shown here. Always wear
safety glasses and appropriate protective equipment, such as chemically resistant
rubber gloves and apron.
Warning! Unspecified Use. Failure to operate this equipment according to the
guidelines and safeguards specified in this manual could result in a hazardous
condition.
Warning! Pinch Hazard. Some areas of the instrument or its components can
present pinch hazards when the instrument is operating. These areas are marked
with the symbol shown here. Keep hands/fingers clear of these areas when the
instrument is operating.
Warning! Software Quality Control. The operator must follow the
manufacturer’s assay package insert when modifying software parameters and
establishing reading, washing, or dispensing methods. Failure to conduct quality
control checks could result in erroneous test data.
Precautions
The following precautions are provided to help avoid damage to the instrument:
Caution: Service. The instrument should be serviced by BioTek authorized
service personnel. Only qualified technical personnel should perform
troubleshooting and service procedures on internal components.
Caution: Environmental Conditions. Do not expose the instrument to
temperature extremes. For proper operation, ambient temperatures should remain
within the range listed in the Specifications section. Performance may be
adversely affected if temperatures fluctuate above or below this range. Storage
temperature limits are broader.
Caution: Sodium Hypochlorite. Do not expose any part of the instrument to
the recommended diluted sodium hypochlorite solution (bleach) for more than 20
minutes. Prolonged contact may damage the instrument surfaces. Be certain to
rinse and thoroughly wipe all surfaces.
Caution: Buffer Solution. Although many precautions have been taken to
ensure that the instrument is as corrosion-proof as possible, the instrument is not
sealed and liquids can seep into sensitive components. Make sure that any spilled
buffer solution is wiped off the instrument. Prolonged exposure to salt solution
may corrode parts of the microplate carrier, movement rail, springs, and other
hardware.

xii | MicroFlo Select™
BioTek Instruments, Inc.
Caution: Chemical Compatibility. Some chemicals may cause irreparable
damage to the instrument. The following chemicals have been deemed safe for use
in the instrument: buffer solutions (such as PBS), saline, surfactants, deionized
water, 70% ethyl, isopropyl, or methyl alcohol, 40% formaldehyde, and 20%
sodium hydroxide. Never use acetic acid, DMSO, or other organic solvents. These
chemicals may cause severe damage to the instrument. Contact BioTek for more
information and prior to using other questionable chemicals.
Caution: Bovine Serum Albumin. Solutions containing proteins, such as
bovine serum albumin (BSA), will compromise the instrument’s performance over
time unless a strict maintenance protocol is adhered to. See Maintenance
procedures regarding BSA.
Caution: External Power Supply. Only use the power supply shipped with the
instrument. Operate this power supply within the listed range of line voltages.
Caution: Disposal. This instrument contains printed circuit boards and wiring
with lead solder. Dispose of the instrument according to Directive 2002/96/EC,
“on waste electrical and electronic equipment (WEEE),” or local ordinances.
Caution: Warranty. Failure to follow preventive maintenance protocols may
void the warranty.
Caution: Shipping Hardware. All shipping hardware must be removed before
operating the instrument and reinstalled before repackaging the instrument for
shipment.
Caution: Do not run the MicroFlo Select without a cassette installed on the pump.
Caution: Electromagnetic Environment. Per IEC 61326-2-6 it is the user’s
responsibility to ensure that a compatible electromagnetic environment for this
instrument is provided and maintained in order that the device will perform as
intended.
Caution: Electromagnetic Compatibility. Do not use this device in close
proximity to sources of strong electromagnetic radiation (e.g., unshielded
intentional RF sources), because these may interfere with the proper operation.

2 | Introduction
BioTek Instruments, Inc.
The MicroFlo Select Microplate Dispenser
The MicroFlo Select (MicroFlo) is a self-contained, user-programmable, universal
microplate dispenser. The following unique combination of features expands applications
far beyond the typical microplate dispenser:
A peristaltic pump with eight individual tubes transfers fluid from a supply
bottle, or up to eight different supply bottles, to various vessels. The pump has
four rollers over which the tubing is stretched.
The tubing is contained in an easy to load and unload cassette which is
attached to the pump head. The pump’s protective cover must be in place to
run a dispense routine.
Three cassette sizes are available: 1 µL, 5 µL, and 10 µL for the most precise
dispensing of volumes from 1 to 9999 µL.
The tubing is autoclavable (steam temperatures and pressures of 121° C and 1
bar (750 mmHg)) and compatible with 70% ethyl or isopropyl alcohol and 0.5%
sodium hypochlorite (bleach) solution.
The dispenser’s standard carrier accommodates 6-, 12-, 24-, 48-, 96-, 384-, and
1536-well plates that comply with SBS microplate standards 4-2004. A custom
carrier is available for dispensing into 12 mm X 75 mm and 13 mm X 100 mm
test tubes. Plate types are stored in the onboard software.
Dispensing can be performed instantly for the most common applications. The
MicroFlo saves the 10 most-recently-used dispense routines for quick access.
Dispense volumes, plate type, and plate maps can be defined on-the-fly.
User-programmable dispense rates provide for a wide range of dispensing
capabilities.
The horizontal dispense position provides for precise positioning of the wells
under the dispense tubes.
A variety of solutions, including buffered saline and various reagents, can be
dispensed.
The intuitive menu-driven software allows you to create and store up to 99
dispense protocols.
The MicroFlo has a low-maintenance design, the result of BioTek’s long history
with liquid-handling instruments.
In addition to operating on a stand-alone basis, the MicroFlo is compatible with
BioTek’s BioStack™ Microplate Stacker and BioStack Twister II Microplate
Handler.
