Holmium Oxide Glass wavelength accuracy calibration standard (241.5-637.5nm)

As far as we're aware, the Firefly FF-WAV-1-UV/VIS is the only Holmium Oxide glass calibration standard that offers the highly-demanded 241.5nm peak for validation of DNA measurements!

Characteristics:

The Firefly FF-WAV-1-UV/VIS offers the following NIST-compliant peak values for calibrating the wavelength accuracy of spectrophotometers:

• 241.5nm
• 279.3nm
• 287.6nm
• 333.8nm
• 360.8nm
• 385.8nm
• 418.5nm
• 453.4nm
• 459.9nm
• 536.4nm
• 637.5nm

Please note:

The measured wavlengths' peaks depend, among other factors, on the slit width of the user's spectrophotometer's monochromator (spectral band-pass) Our calibration measurements are performed with a slit-width of 1nm. Other widths are possible, please contact us.

Advantages of Firefly Scientific's solid state calibration standards:

• Highly accurate and reproducible calibration of your spectrophotometer
• Never need to be replaced
• Never need recalibrating if handled and stored correctly
• Scratch-resistant coating protects optical surfaces
• Can be used in any spectrophotometer (with standard 12.5 x 12.5 x 45.0mm holder)
• Correspond to or surpass NIST requirements and tolerances
• NIST-traceable and compliant
