Yes, the AND MPA20 presents different modes to help reduce user-stress and improve user productivity. Confidently transport and dispense liquid samples with the following:
AUTO mode for standard automatic aspiration and dispensing
Multiple Dispensing mode (MD) for dividing an aspirated volume into multiple dispensings of a lower volume
Mixing mode (MIX) that allows users to set aspirating-dispensing cycles to mix and homogenize samples
Reverse Operation function that is best for when working with viscous samples
Is the A&D MPA-20 single channel electronic pipette better than large-volume mechanical pipettes?
Yes, the AND Weighing MAP-20 pipette is engineered with an electronic control for reliable accuracy. This ensures all dispensed sample quantities do not vary depending on user or user pipetting motion applied. Unlike manual pipettes, these electronic MPA pipettes come with better ergonomics for pain-free operations thus reducing user stress. Aside from presenting easy calibration/adjustment by volume (mL) or by weight (mg) to make sure any error caused by differences in tips used are corrected, A&D MPA pipettes are also considered cost-effective since these can also replace pipette controllers in various applications.
Any other features that would make me want to purchase the A&D MPA-20 single channel pipette?
The AND MPA-20 is feature-packed with its 9 program storage for fast recalls of operations and dispensing volume combinations. It is also built with an audio alert that lets users know when an operation has started. Designed with padding on all four corners of the pipette head and with a long curved finger hook for solid grip, the MPA laboratory pipette ensures safety from impacts. Through its electronic control, instances of unnecessary or excessive sample suctions are avoided.
Is the A&D MPA-20 pipette easy to clean and maintain?
Yes as it is autoclavable. The lower part of the AND MPA20 single channel pipette including the piston and tip holder can be quickly separated for sterilization as well as replacement purposes.

Top 5 Reasons Why You Should Choose The MPA-20
1. Automatic control ensures accuracy for everyone at all times
Unlike manual (mechanical) pipettes, dispensed quantities will not vary with each person or each pipetting motion. Automatic operation ensures uniform accurate pipetting for both novice and expert alike, making anyone’s assays always reliable.
When the volume becomes large, a manual pipette is especially tiring to operate because of the large diameter of the cylinder and long movements of the piston. 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. *1
**1 Our experiment verified that virtually no strain occurs at all after 3,000 repeated pipettings over a 5 hour period
This and other functions such as mixing and reverse operations will dramatically increase your work efficiency and accuracy.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.
4. Easy calibration and adjustment by yourself (User CAL function), either by volume (mL) or weight (mg)
All you have to do is simply input the correct value measured by a balance (A&D’s pipette accuracy testers are recommended) into the MPA-20.
Frequent, outsourced pipette calibration services can be expensive and impractical. With the MPA, you can ensure pipette accuracy by performing calibration at your own facility when needed, increasing the precision of your analyses.This function also corrects for possible errors arising from differences in tip characteristics so you can use your preferred manufacturer’s tips without any worry.
Calibration and display in a unit of weight (mg)
With the MPA series, you can choose to calibrate and display the pipetting amount based on the weight (mg) of the sample itself measured using a balance, instead of volume (µL). This will make it much easier for you to handle liquids that need to be managed by weight, such as a diluted solution of a solid or powder, eliminating the necessity of troublesome density calculations. Additionally, it realizes more precise control of dispensing amounts of liquids whose viscous resistances or behaviors inside tips are different from that of purified water (with which the volume is normally calibrated).
5. Despite all these advantages, price is almost comparable to that of a manual pipette
Other Features of the MPA Pipettes:
Increased resistance to impacts from falls
One of the most common repairs of electronic pipettes is for a broken LCD display due to drops and falls. With padding on the four corners of the head*, the LCD panel of the MPA is designed to be protected from impacts from falls. Also, 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.
User-friendly industrial design
The movement of the trigger can be controlled with the ball of the index finger instead of the thumb while maintaining all fingers in a natural, effortless grip.
Simple function and operation settings
Changing the operation mode, volume(s), aspirating and dispensing speeds*5, 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.
Besides the USB power connecter, the MPA series is equipped with electrode terminals to be hooked onto the following charger devices (all sold separately).
