Variable or Fixed Bandwidth
Optical bandwidth selectable down to 0.5nm is provided by the CE7500
and allows the fine structure of narrow bands to be resolved which
remain unresolved at 2nm bandwidth in instruments such as the CE7400.
Double Beam Optical System
The fully symmetrical optical system measures sample and reference
simultaneously for ultimate accuracy, precision and baseline flatness.
Long term stability is up to ten times better than single beam systems.
Automatic Cell Changers
Automatic changers are available for 4, 6 or 8 cells, providing
rapid sample changing or the facility for full programming.
Sipette Sampling
Samples down to 300 microlitres may be measured in a 10mm cell.
Sampling is under control of the instrument's microprocessor system.
Samples may be saved or pumped to waste.
Ultra-Micro Sampling
Samples of 50µl and less may be accurately measured assisted
by the very small beam size of only 7 x 1mm. All normal cells up
to 100mm pathlength are accommodated.
Sample Temperature Control
Water and thermoelectric temperature control are available for
single cells and automatic cell changers. Temperature is set from
the control panel and displayed on the screen in the latter case.
Dissolution Testing
Versions of the instruments fitted with a special cell compartment
with piping port are available for dissolution testing using Cecil
TD software and a PC. Six and eight cell changers are available.
Batch Sampling
Automatic batch sampling for up to 100 samples is available. The
pump fits within the sample compartment and volume etc is set from
the control panel and displayed on screen. Batch number entry is
provided.
Specular Reflectance
Special accessories enable specular reflectance measurements to
be made. Both fixed angle and variable angle reflectance accessories
are available. The latter is particularly useful for film thickness
measurements.
