Gilson PIPETMAN G Quick Guide

Introduction

PIPETMAN® G is a fully adjustable air-displacement pipette designed for use with disposable tips. It builds upon the renowned accuracy, precision, and reliability of the PIPETMAN series, while significantly reducing pipetting and purge forces for enhanced user comfort during prolonged use.

The range includes eight single-channel models covering volumes from 0.2 μL to 10 mL, and eight multichannel models covering volumes from 1 μL to 300 μL.

Description

Specifications

PIPETMAN G is a high-quality pipette offering excellent accuracy and precision. The performance data presented in the "Maximum Permissible Errors" table were obtained using genuine PIPETMAN® DIAMOND Tips, and these values are guaranteed only when such tips are used.

Maximum Permissible Errors

The following table details the maximum permissible errors, conforming to the ISO 8655-2 standard.

* P5000G and P10mLG models do not have tip ejectors.

Setting the Volume

The volume of liquid to be aspirated is set using the volumeter. The dials are colored either black or red to indicate the position of the decimal point, depending on the model (refer to Figure 3).

The volume is set by turning the thumbwheel or the push button (refer to Figure 4). The push button offers a faster and easier way to set volumes, especially when wearing gloves. The thumbwheel allows for slow, precise adjustments using only one hand.

To achieve maximum accuracy when setting the volume:

• When decreasing the volume setting: Slowly approach the required setting, ensuring not to overshoot the mark.
• When increasing the volume setting: Pass the required value by approximately 1/3 of a turn, then slowly decrease to reach the target volume, ensuring not to overshoot the mark.

Fitting the Tips

To attach a new PIPETMAN DIAMOND Tip, push the tip holder into the tip with a slight twisting motion to ensure a firm, airtight seal.

The PIPETMAN G is equipped with a stainless steel tip ejector and can also be used with a plastic tip ejector, available as an accessory. Refer to the PIPETMAN G User's Guide LT801122 for accessories.

Fitting the Tips on P2G and P10G Models

P2G and P10G models are supplied with the adapter pre-installed, ready for DL10 tips. If D10 tips are to be used, the adapter must be repositioned in the shorter slot following these steps:

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

Ejector Spacer for PIPETMAN G 10 μL Multichannel Models

Depending on the tip used (D10 or DL10), you may need to exchange the ejector spacer. The broadly spaced one is for D10 tips, and the narrowly spaced one is for DL10 tips.

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

PIPETMAN DIAMOND Tips are best fitted using the ROCKY RACK technique, invented by Gilson, available exclusively in their TIPACK and TOWERPACK products.

* Using the broad ejector spacer D10, you can adapt a D10 tip.

Pre-Wetting the Tips

Pre-wetting the tips before pipetting helps prepare them for optimal performance. Ideally, this process involves immersing the tip in the liquid and performing one pipetting step.

Pre-wetting ensures that the volumes you pipette will achieve the specified accuracy and precision.

Aspirating

1. Press the push button to the first stop (this corresponds to the set volume of liquid).
2. Hold the pipette vertically and immerse the tip in the liquid (refer to PIPETMAN G User's Guide LT801122).
3. Release the push button slowly and smoothly (to the top position) to aspirate the set volume of liquid.
4. 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

1. Place the end of the tip against the inside wall of the recipient vessel (at an angle of 10° to 40°).
2. Press the push button slowly and smoothly to the first stop.
3. 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.
4. Release the push button smoothly. Eject the tip by pressing firmly on the tip ejector button.

Maintenance

Routine maintenance helps 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 G User's Guide LT801122, or to replacing the push button, connecting nut, tip ejector, tip holder, seal, and O-ring.
