Research Series is a new
generation laboratory research 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
stoppering or bulk assembly. Hydraulic stoppering is provided by a bottom
up hydraulic cylinder. 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. A coil condenser is located between the product and the
vacuum pump providing maximum condensing surface area and vacuum
pump protection. A 4" vapor port connects the two chambers,
with a 6" option. An isolation valve can be added for end of
drying testing. 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 resulting in
consistent and repeatable drying. All units come with one product
tray per shelf, either a removable bottom or bulk.
Options include a Shelf Latching Kit, Isolation Valve,
Capacitance Manometer, Moisture Sensor, Clean Room Configuration,
Sample Extractor, 6"/8" vapor ports.
