Laboratory Series is a new generation freeze dryer
that is both a shelf and manifold dryer. Product can be
loaded on the shelves and frozen prior to drying or can be frozen in
an optional shell freezer for manifold drying. A rectangular chamber
offers a compact profile with either a two shelf stoppering or three
shelf bulk assembly. Both options have a radiant heat plate above
the top shelf for uniform drying on all shelves. All internal surfaces are
constructed of 316L stainless steel and offer a polish of 20 Ra or
better.
For the fastest drying rates and maximum pump
protection the condenser is located inside the chamber beneath the bottom
shelf. Hot gas is used for defrosting the condenser when drying is
complete. Fluid filled hollow shelves with a serpentine fluid path
provide the most uniform shelf temperature possible and results in
consistent and repeatable drying. All units come with one product
tray per shelf, either a removable bottom or bulk. Pneumatic stoppering
is provided by a bottom up pneumatic cylinder, which is powered by a
self-contained air pump.
