Specifications

PIPETMAN® is a high-quality pipette that offers excellent accuracy and precision. The data provided in the Maximum Permissible Errors table on page 4 was obtained using PIPETMAN® DIAMOND Tips.
These values are guaranteed only when genuine PIPETMAN DIAMOND Tips are used.
NOTICE
With a precise pipetting technique the P2 model may be used to aspirate volumes as low as 0.1 µL and the P10 model as low as 0.5 µL.
Maximum Permissible Errors
The data in the following table conforms to the ISO 8655-2 standard. GILSON
PIPETMAN P2 Metal Ejector - Description 1 CV means Coefficient of Variation
P10 model can be used up to 0.5 μL with a precise pipetting technique.
P5000 and P10mL do not have tip ejectors.
Gilson maximum permissible errors are only guaranteed when PIPETMAN® pipettes are used with the recommended PIPETMAN® DIAMOND Tips. GILSON PIPETMAN P2
Metal Ejector - Description 2 Setting the Volume
The volume of liquid to be aspirated is set using the volume display. The dial colors are either black or red to indicate the position of the decimal point, depending on the model (refer to Figure 3). Figure 3
Dial colors by model
The volume is set by turning the thumbwheel or the push button (refer to Figure 4). The push button makes it easier and faster to set volumes, especially when wearing gloves.
The thumbwheel may be turned using only one hand to slowly reach the required setting.
To achieve maximum accuracy when setting the volume, proceed as follows:
When decreasing the volume setting, slowly reach the required setting,making sure to not overshoot the mark.
Figure 4
Location of push button and thumbwheel
When increasing the volume setting, pass the required value by 1/3 of a turn and then slowly decrease to reach the volume, making sure to not overshoot the mark.

Fitting the Tips

Single Channel Models
To fit a new PIPETMAN DIAMOND Tip, push the tip holder into the tip using a slight twisting motion to ensure a ﬁrm, airtight seal.

NOTICE
D5000 and D10mL PIPETMAN DIAMOND tips do not have any filter. P5000 and P10mL models are sold with a bag of 10 filters. For more details, refer to PIPETMAN User’s Guide LT801122.

Fitting the Tips on P2 and P10 Models

NOTE
For the P2 and P10 models, a dualposition adapter (plastic) is required to fit DL10 tips (long tips) or D10 tips (short tips). The metallic rod of the tip ejector is shaped so the adapter may be clipped to it in either position.
P2 and P10 models are delivered with the adapter in place, ready-to-use DL10 tips. If D10 tips are used, the adapter must be repositioned in the shorter slot as follows:

Pull the adapter down from the metallic rod.
Turn the adapter 180°.
Reﬁt the adapter so the end of the metallic rod engages the shorter slot of the adapter.

NOTE
The dual position is autoclavable.

Multichannel models

PIPETMAN® DIAMOND Tips are best fitted with the ROCKY RACK technique, invented by Gilson, available only in our TIPACK and TOWERPACK.

Ejector Spacer for PIPETMAN® 10 µL Multichannel Models

According to the tip used, D10 or DL10, you may have to exchange the ejector spacer. The broadly spaced one is for D10, and the narrowly spaced one is for DL10.

Remove the tip ejector, keeping both ejector locks depressed. Pull the tip ejector down.
Gently press the tabs from the ejector spacer and remove it from the tip ejector.
Insert the alternative ejector spacer and click it to the tip ejector.
To refit the tip ejector, gently re-insert the tip ejector vertically into the rails of the ejector support.

Pre-Wetting the Tips

Pre-wetting the tips before pipetting helps prepare the tips for the best pipetting performance. Ideally, the prewet includes both immersing the tip in the liquid and performing one pipetting step.
Pre-wetting the tips helps ensure that volumes your pipette’s volume will achieve accuracy and precision within specifications.

Aspirating

Press the push button to the first stop (this corresponds to the set volume of liquid).
Hold the pipette vertically and immerse the tip in the liquid (refer to PIPETMAN® User’s Guide LT801122 available on gilson.com).
Release the push button slowly and smoothly (to the top position) to aspirate the set volume of liquid.
Wait one second, and then withdraw the pipette tip from the liquid. You may wipe any droplets away from the outside of the tip using a medical wipe; however, if you do so, take care to avoid touching the tip’s orifice.

Dispensing

Place the end of the tip against the inside wall of the recipient vessel (at an angle of 10° to 40°).
Press the push button slowly and smoothly to the first stop.
Wait for at least one second, then press the push button to the second stop to expel any residual liquid from the tip. Keep the push button pressed fully down and (while removing the pipette) draw the tip along the inside surface of the vessel.
Release the push button smoothly. Eject the tip by pressing firmly on the tip ejector button.

NOTICE
It is recommended to regularly verify the volume displayed on the dial while pipetting.

Maintenance

Routine maintenance will help keep your pipette in good condition, ensuring a continued high level of performance.
Maintenance is limited to cleaning or autoclaving the parts speciﬁed in the PIPETMAN® User’s Guide LT801122, or replacing the push button, connecting nut, tip ejector, tip holder, seal, and O-ring.
NOTICE
Gilson recommends maintenance and calibration at least annually, more frequently as needed, depending on use.
NOTICE
PIPETMAN® P2 and P10 should not be disassembled. You may only replace the push button, tip ejector, and its dual-position adapter. With these pipettes, if the tip holder is damaged, the piston may also be damaged. After replacing any parts, you should verify
the performance of your pipette following the verification procedure available on the Gilson website (www.gilson.com). If the pipette needs to be readjusted, please contact your local authorized Gilson Service Center.
NOTICE
Decreased pipetting forces are due to the design of the piston assembly, which includes a very high-quality lubricant (part number 5440011070). The use of any other lubricant voids the warranty of this pipette.

Cleaning and Decontamination

PIPETMAN is designed so the parts normally in contact with liquid contaminants can easily be cleaned and decontaminated.
For further information, please refer to PIPETMAN User’s Guide LT801122 available on gilson.com.

Warranty

Gilson warrants this pipette against defects in material under normal use and service for a period of three years for both single channel and multichannel models from the date of purchase.
This warranty shall not apply to pipettes which are subject to abnormal use and/or improper or inadequate maintenance (contrary to the recommendations given in the user’s guide), including, but not limited to pipettes that have been subjected to physical damage, improper handling, or spillage or exposure to any corrosive environment. This warranty shall also be void in the event pipettes are altered or modified by any party other than Gilson or its designates. Gilson’s sole liability under this warranty shall be limited to, at Gilson’s sole option, repair or replacement of any defective components of pipettes or refund of the purchase price paid for such pipettes. Routine cleaning, control and recalibration are not covered under the warranty. The replacement of wearing parts such as seals, O-rings, broken pistons assembly, and broken tip holders are not covered under the warranty.

NOTICE
Yearly routine maintenance is highly recommended to keep your pipette in good condition, ensuring a continued high level of performance.=
