Introduction to the Multidrop Pico

dispenser

The Multidrop Pico dispenser provides fast and reliable dispensing

performance across a large dynamic range, eliminating slow, wasteful,

and error-prone manual serial dilutions and enabling assay

miniaturization through low-volume assay component addition.

The Multidrop Pico dispenser provides fast and reliable dispensing

across a wide range of life science applications:

∂Dose-response curves for small molecule and biomolecule-based

drug discovery research

∂Drug-drug synergy experiments for drug discovery

∂Low-volume assay component dispensing of a wide range of

fluids into microplates

∂Complex enzyme kinetic studies

∂DMPK standards

Using single-use cassettes to help avoid the possibility of cross-

contamination, the Multidrop Pico dispenser offers non-contact digital

dispensing in the picoliter to microliter range. It combines walk-up

convenience, ready-to-run performance and flexible, intuitive

experiment design software to increase research productivity, reliability

of results, and speed of life science research.

Even the most complex experimental plate layouts, such as drug-drug

interaction (synergy) studies, can be made simple. Titrating one drug

down the plate while another is titrated orthogonally across the plate

enables two or more drug doses to be independently generated in every

well. In addition, plate layouts can be randomized to reduce the impact

of edge effects, increasing the integrity of the experimental data. The

Multidrop Pico dispenser offers a convenient solution to address the

most challenging experiments.

The Multidrop Pico dispenser offers non-contact digital dispensing

utilizing single-use cassettes to avoid contamination in picoliter to

microliter range. It increases research productivity by reliable results

provided at higher speed using flexible and intuitive experiment design

software.

The safety precautions and personal protective equipment (PPE)

specified by your employer for chemicals used and fluid transfer

operations and disposal should be used when operating the Multidrop

Pico dispenser and handling these materials.

The Multidrop Pico dispenser was designed with chemical safety in

mind; however, it does dispense picoliter droplets of fluid and generates

a small amount (less than 1 %) by volume, of very small aerosol

droplets that might not be trapped within the well plate that you are

dispensing into. If the fluids are known or suspected to be an inhalation

or contact hazard, use the Multidrop Pico dispenser in an enclosure,

with an exhaust, such as a lab fume hood.

The Multidrop Pico dispenser typically requires a single manual

pipetting operation for each dispensed compound. In most situations,

using the Multidrop Pico dispenser in the intended manner decreases

the frequency of shoulder, arm, and wrist motions and so decreases the

stress on these joints compared to traditional methods.

To minimize ergonomic risks associated with the use of the Multidrop

Pico dispenser, consider the following work area design ideas:

•Place the Multidrop Pico dispenser on a work bench at a height

that allows for proper visual and physical access for operators.

Having the Multidrop Pico dispenser too high can lead to

greater shoulder elevation when pipetting into the cassette and

having the Multidrop Pico dispenser too low can lead to

increased neck and back flexion.

•If an operator is too short to comfortably access the Multidrop

Pico dispenser, consider moving the Multidrop Pico dispenser

to a lower bench height. Alternatively, use a footstool or high

lab stool that adjusts to the proper work height.

•Place the Multidrop Pico dispenser close to the front of the

work surface to minimize the distance the operator must reach

to pipette into the cassette.

•Place the pipette tip disposal receptacle close to the Multidrop

Pico dispenser.

•Place the computer keyboard close to the Multidrop Pico

dispenser to minimize reach distance.

•Adjust the computer monitor height and screen angle for good

physical and visual access during Multidrop Pico dispenser

operation.

•Perform data analysis at a separate ergonomically designed

workstation whenever possible rather than at the Multidrop

Pico dispenser computer.
