Super Aquarius Spectrophotometers

Specifications and Ordering of spectrophotometers and accessories

Cecil Instruments policy is one of continuous development. We therefore reserve the right to change specifications without notice.

Some Examples of Software:-

Assay Program

Construction and entry of mathematical formulae involving measurements at multiple wavelengths with automatic computation of assay results.


Fast data transfer to PC for use with Excel or other spread sheets.

Quant M

Multi wavelength assays at 2 or 3 wavelengths, Warburg and Christian assays at 2 or 3 wavelengths, wine assay, at up to 10 wavelengths.


The instrument will automatically perform a wavelength scan and perform a variety of numerical analyses of colour.

Quant P

Protein assay using the methods of Lowry, Bradford, Biuret and BCA.

Quant S

Quantitation of corrected bands, difference spectra, spectral stripping, overlayed spectra, spectral storage.

Program C

Cell program for up to 4, 6 or 8 cells.

Program W

Wavelength program for up to 10 wavelengths and timed interval measurements at a fixed wavelength.


Wavelength scans with peak labelling and peak tables. Time course plots while re-processing.


Kinetic measurements with plots, reprocessing of data.

Kinetics M

Multi-cell Kinetics linked with autocell changing, and plotting of reaction curves.


Absorbance and Wavelength validation using certified standards or liquids. Validation of optical bandwidth, etc.
