To install the Prep-20 adaptor, remove the two green rubber plugs on the left, front
and right, front of the fraction collector. After attaching the Tygon tubing, insert the
Prep-20 adaptor into the preparative rack holder slots. Notice that the drain trough
slopes slightly towards the drain funnel. The collection port tubing extends down the
front of the fraction collector.
Note:
The Prep-20 adaptor is rated for use with flow rates up to 100 ml/min.
(For discussion of the plumbing for high flow rates, see
Bottles
Place the rack positioning tray, deep side facing up, and place the bottles in the
circles labeled A, B, C, and D. Adjust the fraction collector head appropriately for the
height of the bottles being used.
Adjusting the Drophead Height
The BioFrac fraction collector accommodates collection vessel heights up to 150
mm. Detents, arranged at predefined heights, are positioned along both columns for
added security. The detent positions accommodate all standard tube and
microplate heights. Lock pins fit snugly within the detents to secure the control
module height and prevent the control module from slipping.
