XP Gravity Portable Pipet-Aid® with 110V

Speed Controls: The XP Gravity has three settings on each button to set the desired speed range.  The top (fill) button features S (slow), M (medium), and F (fast), while the bottom (empty) features S (slow), M (medium), and G (gravity). The fill and empty buttons are independent of each other and can be set at different speeds. The speeds are changed by simply rotating the button until a detent is felt and the letter is upright when held in the right hand. The buttons are also proportional in nature. As with all other Pipet-Aids, the further you depress the button, faster filling or dispensing will result. With both buttons set at “M”, the XP will operate at the same speed as the Portable Pipet-Aid. Rotating the button to “S” will reduce the speed to approximately half of the medium speed while rotating to “F” will double the medium speed.  In the case of the XP Gravity, changing the empty button to G will drain the pipette using gravity, and not the pump. DO NOT CHANGE SPEED RANGES WITH LIQUID IN THE PIPETTE.

Changing the Filter & Nosepiece Removal (View a video on the “Maintenance Video” tab): Just like the standard XP, the XP Gravity has a one piece nosepiece that contains the filter and rubber insert. This nosepiece locks into place and will not loosen when removing the pipette. To remove nosepiece, slide the nosepiece release button towards the handle and turn the nosepiece one quarter turn counter-clockwise.

Battery Replacement (View a video on the “Maintenance Video” tab): The battery is contained in the upper portion of the handle. Removal of one Philips screw (B), will enable you to remove the battery compartment door which will give you access to the battery. Use only Drummond replacement batteries (4-000-035). Under normal conditions, these batteries should last approximately 2 years.

Charging the Battery: The Drummond replacement battery is a Ni-MH battery which should be charged overnight following use. No “memory” will be developed and overcharging is not a problem.

Use of the Removable Stand: This lightweight stand slides on to the top of the XP enabling the user to set the Pipet-Aid XP Gravity down without removing or emptying the pipette. The stand will prevent liquid from running back into the nosepiece and prevent the pipette tip from contacting anything thus maintaining sterility. When not needed, the stand is easily removed.
