Each purchased Spectrophotometer is supplied complete with single cell holder, power cable, operators manual and short form instructions.

Specifications and Ordering of spectrophotometer and accessories

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

Some Examples of Software:-


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


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


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