This user guide explains how to adjust the Eppendorf Xplorer electronic pipette for different liquids, altitudes, and tip geometries to ensure dispensing…
The Eppendorf Xplorer is an electronic piston-stroke pipette designed to compensate for physical effects such as temperature, air pressure, and humidity that can affect dispensing accuracy. Unlike mechanical pipettes, it allows for easy readjustment to account for these variables, ensuring precise volume delivery even when using non-aqueous solutions or at high altitudes.
The device offers several individual adjustment options, including settings for specific liquid types (like ethanol or glycerol), compatibility with elongated pipette tips (epT.I.P.S. long), and geographic altitude correction. Users can also perform 1, 2, or 3-point adjustments using a balance to fine-tune the piston stroke based on the exact density of the solution being dispensed.
| Maximum altitude correction | 5000 m |
|---|---|
| Altitude adjustment increment | 250 m (820 ft) |
| Balance resolution for small volumes | 0.001 mg |
Yes, the factory setting can be changed to consider the density of specific liquids like ethanol or glycerol for greater accuracy.
Yes, it can be adjusted to account for the different lengths of pipette tips such as epT.I.P.S. long to improve dispensing accuracy.
It uses a 'Geographic altitude' adjustment function to correct the stroke based on the air pressure at the specific location's height above sea level.
