Now take a moment to consider the facts presented here. You will then realize why A&D’s new and original electronic pipettes, the MPA series, should be your future choice in pipettes!
Unlike manual pipettes, dispensed quantities will not vary with each individual or each
pipetting motion. Automatic operation ensures uniform accurate pipetting for both
novice and expert alike, making anyone’s assays always reliable.
Stress-minimized, pain-free operation
Does your thumb hurt when pipetting Operating a manual pipette requires holding out
the thumb perpendicular to the hand and then pushing the plunger all the way down
with a force of a few kilograms. Such irregular movement can easily cause a repetitive
strain injury (RSI) in the base of the thumb as you repeat it day in, day out.
With the MPA series, it is possible to control the plunger
by lightly pressing a key with the ball of the forefinger
(like pulling a trigger), while maintaining all fingers in a
natural, effortless grip. No longer will hours or days of
pipetting make you feel any pain in your thumb
Various useful pipetting modes
Apart from standard automatic aspirating and dispensing (AUTO mode), the following
functions help greatly reduce time, stress and error associated with certain pipetting tasks
Multiple dispensing (MD) mode
The MD mode lets you divide one aspirated volume (e.g. 1200
µL) into multiple dispensings of a smaller volume (e.g. 100 µL
× 12 times). Use of this function will dramatically increase
efficiency when you have to deliver the same amount of
sample repeatedly into microplate wells, etc.
The MPA series automatically prevents error due to backlash which presents itself when the operation switches from
aspirating to dispensing. You therefore need not discard the
first dispensing volume as being inaccurate, as is the case with
conventional electronic pipettes.
Mixing (MIX) mode
In MIX mode the pipette executes with one key press a set
number of aspirating-dispensing cycles to mix and
homogenize the solution in the receiving vessel. The same task
using a manual pipette particularly tires your thumb and is
also difficult to perform correctly when the mixing volume is
small (prone to mix air and produce bubbles)
Reverse operation
When reverse operation is selected, the pipette first aspirates a
volume larger than the set dispensing volume, and discards
the excess volume after delivery. This function is recommended
for viscous samples that tend to linger in the tip
Preventive measures against damage by falls
Did you know that one of the most common repairs of
electronic pipettes is for a broken LCD or electronic section due
to dropping With padding set on the four corners of the head those sections of the MPA series are designed to be protected
from impacts from falls as much as possible
Meanwhile, the finger hook that rests on your middle finger is
long and curved in such a way that the pipette will remain
perched in the hand even when the grip is loosened.
Quickly detachable lower part
The MPA series entails a much smaller risk of contamination inside the cylinder since
electronic control produces no accidental, excessive suction of the sample.
When necessary, the lower part of the MPA series (including the tip holder and
piston) can be quickly separated for autoclave sterilization (121 °C, 2 atm, 20 min) or
replacement with a new one (supplied as an accessory – AX-LOW-10/20/200/1200)
Simple function and operation settings
Changing the operation mode, volume(s), aspirating and dispensing speeds, etc.,
is simple and straightforward. Further, up to nine combinations of these settings
can be saved in the pipette for immediate recall at later times.
Battery and Charging Options
The MPA series receives power supply from either an AC adapter or lithium-ion
rechargeable battery (1,800 pipettings guaranteed on a full charge). You can also
use the pipette without any hitches while charging the battery at the same time via
USB connection.
