Shelf-Latching
The product shelf assembly used in the manufacture LyoStar™ 3 lyophilizers is
designed with a moveable shelf stack, which is primarily used to facilitate the
stoppering of product vials. However, the ability of the shelf stack to move up and
down also serves a second purpose. Using the shelf-latching kits that are provided
with your unit, the shelf arrangement may be modified to increase the distance
between shelves when processing product in large vials that do not fit into the
standard shelf clearance of the unit.
Note: The use of a shelf-latching kit will reduce the total number of usable shelves in your
product chamber while increasing shelf clearance.
The shelf-latching kits with allow for:
2 to 1 shelf-latching on a 2-shelf unit.
•
3 to 2 and 3 to 1 shelf-latching on a 3-shelf unit.
•
4 to 3, 4 to 2 and 4 to 1 shelf-latching on a 4-shelf unit.
•
The following procedure demonstrates the use of a shelf-latching kit that allows the
operator of a three-shelf LyoStar™ 3 lyophilizer to process and stopper on only two
shelves within the product chamber. The instructions are essentially the same for
each latching kit.
To install the shelf-latching kit:
Close the product chamber door and use the stoppering system to manually 1.
move all of the shelves into the full upright position.
Locate the threaded rods and wing nuts on the top of the shelf assembly. 2.
