1. FOR SAFE USE

1-1 Precautions on using the pipette

DANGER

- This instrument is not an explosion proof instrument. Do not use the pipette in an environment where there is a risk of explosion, or use it for explosive chemicals that may cause explosion.

- When using potentially harmful solutions, such as infectious bacteria or viruses,

radioactive substances that have a risk of exposure, or poisons, exercise extreme caution and follow all safety measures.

CAUTION

- When using a corrosive solution such as an organic solvent, confirm the chemical-proofness of the tip or pipette. When confirming material of the pipette, refer to “7-5 Parts names”.

- Do not attempt to disassemble or repair the pipette by yourself. Refer to “14. TROUBLE SHOOTING” when it appears that the pipette has a mechanical error.

1-2 Precautions on handling the battery

The MPA series use the high-density lithium-ion battery. To prevent injuries or accidents due to a leaking battery, heat generation, fire or burst, and to ensure safe use, be sure to keep the manual on hand.

DANGER

- Do not dispose of the battery in fire, do not heat it, do not disassemble or modify it.

- Do not splash water on the battery, or do not keep the battery in a location at high temperature or high humidity.

- Do not allow battery contacts to contact metal. When keeping or carrying the battery, be sure not to allow the battery to contact metal.

WARNING

- Recharge the battery with pipette installed. The pipette can be used even when the battery is being recharged.

- When recharging is unsuccessful even after charging for the specified time (Five hours up to fully recharge), stop recharging the battery.

- Use only the battery supplied with the pipette. Do not use other batteries.

CAUTION

- Do not use a leaking battery.

- Because the battery body may become hot when using the pipette continuously for a long time, take care not to get burned when handling it.

- Should you get battery fluid from a leaking battery in your eye, immediately flush with copious amounts of water and seek immediate medical attention. Should the liquid contact the clothes or skin, rinse immediately with copious amounts of water.

2. INTRODUCTION

Thank you for purchasing the MPA series electronic pipette. To ensure safe use of the product, be sure to read the manual thoroughly.

3. FEATURE

The MPA series is a high precision and performance electronic pipette that achieves operability without putting a burden on the hand. This pipette is developed for the purpose to prevent RSI (Repetitive Strain Injury) which may occur when repeatedly using a manual pipette, and does not require any special skill so anyone can easily and accurately dispense the specified volume.

□ Pipette is operated by merely pressing a key, the degree*1 of fatigue is 1/100 or

less of when using pipette manually. (*1 Calculated by operating force and movement)

□ It has an ergonomic design, fitting the hand for easy adjustments and operation. □ Using a lithium-ion battery enables usage for long periods of time.*2

（*2 Approximately 1,800 dispensing operations are possible on a full charge）

□ Impact-absorbing pads adopted to fully protect against falling. (Patent has been

applied for)

4. COMPLIANCE

Compliance with FCC Rules

Please note that this device generates, uses and can radiate radio frequency energy. This device has been tested and has been found to comply with the limits of a Class A computing device pursuant to Subpart J of Part 15 of FCC rules. These rules are designed to provide reasonable protection against interference when this device is operated in a commercial environment. If this unit is operated in a residential area, it may cause some interference and under these circumstances the user would be required to take, at his own expense, whatever measures are necessary to eliminate the interference. (FCC = Federal Communications Commission in the U.S.A.)

Compliance With EMC Directives of CE mark

This device features radio interference suppression, safety regulation and restriction of Hazardous Substances in compliance with the following Council Directives

Council directive 2004/108/EC EN61326 EMC directive Council directive 2006/95/EC EN61010-1 Low voltage directive

Council directive 2011/65/EU EN50581 Restriction of the use of certain

Hazardous Substances The CE mark is an official mandatory European marking. Please note that any electronic product must comply with local laws and regulations when sold or used anywhere outside Europe.

5. MPA FUNCTION

□ The pipette has three modes where advantages of electromotion are utilized.

(Refer to “9. FUNCTION AND HOW TO USE”)

- Standard mode (AUTO) This is for basic pipette operation. In this mode, the pipette aspirates once and

then dispenses once.

- Multiple dispensing mode (MD) This is for dispensing liquid on a microplate, etc. In this mode, the pipette aspirates

once and dispenses several times.

- Mixing mode (MIX) This is a useful operation when uniformly mixing different types of liquids. In this

mode, the pipette repeats a cycle of aspirating and dispensing.

□ User setting allows storage within the pipette of up to nine programs containing

operating mode and dispensed volume. By reading them out when necessary, operation for setting again can be omitted. Settings from the prior use are stored in memory even with the power turned off.

□ The pipette is equipped with the reverse operation suitable for dispensing a liquid

that has a tendency to remain in the tip. (Refer to “9-6 Reverse operation (Dispensing liquid that tends to remain in the tip)”)

□ The pipette also has “Dispensing correction function” (Patent applied for) with

multiple dispensing to cancel errors due to backlash. It enables the dispensing of liquids precisely without difference due to operators. (Refer to “9-9 “Dispensing correction function” for multiple dispensing”)

□ Various kinds of tips can be used. (The height of the tip ejector can be adjusted)

(Refer to “12. ADJUSTING HEIGHT OF THE TIP EJECTOR”)

□ Calibration (adjustment) of dispensed volumes is easy. (User CAL function). Even

differences in dispensed amounts due to tip differences can be corrected. (Refer to

“11-1 Volume calibration function (μL calibration function)”) (Patent applied for)

□ Dispensing by weight is also available. Refer to “11-3 Dispensing in a unit of

weight (in mg unit)”) (Patent applied for)
