INTRODUCTION
The Savant SC250 Express centrifugal vacuum concentrator, offers fast,
reliable batch processing of samples. It effectively removes a broad range of
aggressive and volatile solvents to concentrate or dry solutes, analytes and
residues while providing complete sample recovery. The heavy-duty Universal
Rotor is optimized for efficient large sample processing while accommodating
various sample handling formats.
The combination of vacuum, applied to the sample chamber from an external
source, and centrifugal action promotes solvent evaporation without sample
loss due to foaming or bumping. The evaporation process is accelerated with
the addition of chamber heat to counteract the extreme evaporative cooling of
the samples. The concentration process is completed with the addition of a
vapor condensation trap available separately for virtually 100% solvent
recovery. This results in a thorough evaporation process in a safe environment
for both the sample and the user.
The compact, industrial strength SC250 Express features:
•
heavy-duty Universal Rotor for high sample throughput and flexible sample
handling formats; carriers capable of holding interchangeable rotor blocks
for vials and tubes as well as multiple microplates
•
ultimate chemical resistance to aggressive solvents with the following
provisions:
- rugged stainless steel magnetic drive lubricated with acid-resistant
grease
- Teflon
®
and Teflon
®
coated materials used exclusively in the vapor path
- dual valve manifold positioned to reduce solvent vapor exposure
- dedicated bleed port added to assure unidirectional vapor flow and
to purge bearings with fresh air
•
faster evaporation rate with the following enhancements:
- enlarged vacuum port increases cross-section of vapor path
- built-in chamber radiant lamps positioned for optimal evaporation
temperature of samples in the Universal Rotor
- heated glass cover adds radiant heat to samples and prevents
condensation of DMSO on cover
•
microprocessor control of run and heat times offer fully unattended,
automatic operation
•
built-in digital vacuum gauge and added sight glass allow continuous
monitoring of process and system status as well as the visual inspection
of the rotor movement
