Stalwart

Real time display of collector temperature & vacuum level
Automatic control of freeze-drying process, program can be set by users
Can be switched to manual operation mode at any time needed, to realize entire control of freeze-drying process.
Record vacuum rate, cold trap temperature, material temperature, shelf temperature, USB port for data download.
Alarms for temperature and vacuum level, guarantee the safety and stability of operation.
Digital password protection

The cold trap cavity and material shelf are made of 304L stainless steel, corrosion-resistant and easy to clean.
Material pre-freezing function.
Automatic defrost for easy use.
The cold trap drying chamber is made in aviation-class plexiglass transparent material, which can observe material status clearly.
World-class compressor, optimized cooling efficiency, fast cooling, lower power consumption & environment friendly.
Two temperature ranges available. -60° C models for aqueous samples, and -85° C models for low eutectic temperatures materials.
Various drying accessories to process flasks, vials, ampoules or bulk.
