VirTis® BenchTop™ “K” Series Freeze Dryers were developed to meet the demand for a research Freeze Dryer that would provide a full range of laboratory processing capability. The compact design plus the wide range of options and accessories make these freeze dryers the most versatile available. 
The BenchTop “K” Series Freeze Dryers are offered in a range of condenser temperatures from -55°C to -105°C. This wide range of condenser temperatures provides the drying power required to freeze dry all aqueous and most organic based samples. Condenser sizes range from 3 to 9 liters, allowing for processing of a few samples or multiple user applications. 
A wide selection of optional accessories allows any shape or size sample container to be processed. Manifolds can accommodate up to 18 flasks at once and adjustable racks allow samples in dishes or Tyvek® bags to be placed inside the manifold for drying. 
Stoppering assemblies enable vials to be easily stoppered under vacuum for long-term storage. Heated racks can be used to speed up the drying process and reduce processing time. 
VirTis BenchTop “K” Series are extremely efficient and easy to operate. The Sentry 2.0 Microprocessor Controller provides a userfriendly interface with full function control for all BenchTop freeze dryers. A graphical wave LED displays system status while a backlit synoptic LCD enables at-a-glance monitoring of all operational systems. An optional heat controller enables temperature to be more precisely controlled to shorten drying times. Powerful workstation software provides complete data collection and historical trending of your freeze drying cycles. 
An automated hot gas routine allows defrosting in minutes to enable quick turnaround of valuable samples.
