Stoppering
The hydraulic stoppering mechanism may be operated under vacuum or after
backfilling the chamber with inert gas. Operation of the stoppering system while the
unit is at low temperatures is not recommended (
i.e. , below -5° C).
Shelf spacing may need to be adjusted to accommodate various size vials. The
LyoStar™ 3’s shelf-latching kits may be used to modify the interdistance between
shelves allowing you to process and adequately stopper vials of various sizes.
To stopper:
Press and hold the stoppering switch. 1.
Note: The stoppering system is equipped with a safety interlock. Movement of the
stoppering mechanism up or down can only be achieved with the product chamber
door in the closed position.
The compressing shelf shall stop after the vials are fully seated. 2.
After stoppering, return the shelves to the original position. The compressing 3.
shelf will stop at the initial position.
Note: Shelves must be properly aligned and level to fully insert the stoppers.
Incomplete stoppering across the shelf area may indicate that the shelf assembly is
not properly aligned or level.
Once vials have been stoppered and the product shelves have returned to 4.
their original loading position, chamber vacuum may be broken and the
chamber door may be opened.
If removable bottom trays are used, samples shall be removed by reinserting 5.
the tray bottoms under the sample containers and then removing the full trays
from the chamber.
Note: LyoStar™ 3 lyophilizers are supplied with removable bottom stainless steel
trays. These trays allow for greater heat transfer from the shelf to the vial sample. Do
not use removable bottom trays when bulk drying.
