The new SI-BF-100 is an LED-based
fl uorometer for life science applications. It is
ideally suited for ratiometric calcium detection
(FURA-2) and ATPase detection (via NADH
fl uorescence). With up to seven LED modules
(wavelengths), the SI-BF-100 covers many
fl uorometric applications in neuroscience and
cell biology.
Recent advancements in optics and LED
technology simplify ratiometric calcium
imaging, making this equipment more
affordable. A breakthrough in WPI patented
technology allows the SI-BF-100 to use
wavelengths below 380nm and produce
more light in those spectra. This technology
signifi cantly cuts the cost of photometric
calcium imaging without sacrifi cing resolution
or quality.
• LED light sources require less power,
give off less
heat and are more
compact and affordable
• Sampling rates up to 1kHz (1,000
ratios/second maximum). At lower
speeds, signal averaging is used for
noise reduction.
• Two auto ranging photomultiplier
inputs allow you to monitor multiple
wavelengths from a single emission
output that can be comprised of
Biofluorometer
Now more reliable,
simplifi ed and affordable
any wavelength of light for which an LED
module is available
• Using a separate reference channel,
ultra-stable, continuous ratio calculations
automatically compensate for LED
intensity drift. This ensures less noise and
produces more accurate measurements.
• Application-specifi c probes are available
for existing tissue baths and cuvette
systems.
• Ratio noise is <0.05 peak to peak, drift is
less than 0.1 unit/hour
• The warm up time of less than one
minute is a dramatic improvement over
the common 20–60 minutes required by
xenon or mercury light sources
• Replace the emission fi lter easily or
change the LED modules to transform
the SI-BF-100 into a general purpose
fl uorometer for many other applications
