Section VIII - Quadra 4 Accessories
Tomtec provides a wide variety of accessories for the Quadra 4 to expand its value
for specific applications.
1.0 Custom Reservoirs
Tomtec will specially fabricate custom reservoirs to match your pipetting pattern.
For example, many clients leave the first row of wells open without compounds to
facilitate adding standards and controls to the pattern. Tomtec can provide a
special reservoir with specific wells joined in the first row. Using pipeline pipetting,
the pipettor would aspirate the standards and controls from the first row and air in
the balance of the tips. When moving to the compound plate the pipettor will
aspirate air in the empty first row and compounds from the rest.
1.1 Keeping Participate Matter in Suspension
There are a number of applications that require dispensing liquids containing
particular matter that must be kept in uniform suspension. If the suspension is not
uniform, then the end results may be affected. Examples are magnetic beads, SPA
beads, cells, etc. Tomtec offers the following, depending on the applications
requirements.
1.2 Stirring Reservoir
A self-contained battery operated stirring reservoir nest will sit on the shuttle. It has three
magnetic fleas to stir the contents of the reservoir.
