4.0 Quadra 4 Disposable Multi Volume Head (DMV)
QUADRA 4 – DMV PIPETTING HEAD
The Quadra 4 has an optional DMV Pipetting Head that offers the user the ability to
operate the instrument with three different volume pipetting tips with one pipetting head.
The DMV Head uses 250ul, 50ul and 20ul disposable pipetting tips. The user can select
which volume pipetting tips they wish to use by selecting the color coded tip load fixture in
the Quadra 4 Command Software components menu in upper left corner. The tip load
fixture colors are coordinated to the colors of the pipetting tip bases associated with each
volume.
- Gray – 20ul Pipette Tips – TOMTEC P/N 196-305
- Green – 50ul Pipette Tips – TOMTEC P/N 196-307
- Blue – 250ul Pipette Tips – TOMTEC P/N 196-306
When the Quadra 4 is programmed to pipette, the user selects proper tip based on the
maximum tip volume capacity for the application being used. This pipette head is
mechanically aligned to this particular Quadra 4 instrument at the factory. This
calibration should not need to be redone during normal operation. Should the pipetting
head or stage be removed or replaced, a new mechanical offset will need to be
determined and installed in the software.
To determine the mechanical offset, the following procedure should be followed.
TIP LOAD HEIGHT
Tip Load Heights for the 20ul, 50ul and 250ul tips must all be set before the Electronic Z
offset is determined and set in the Quadra 4 Command Software.
