General
Lovibond® optical cells are used in all types of spectro-photometers, fluorimeters, absorptiometers and
colorimeters throughout the world. The accuracy of the results obtained from these instruments must in
part depend on the accuracy of the cell used.
Lovibond® cells are manufactured by a specially developed fusing process which makes them resistant to
acids and chemical attack. Only highest grade materials are used and all Lovibond® cells are thoroughly
checked for quality and accuracy.

Liquid Reference Standards
The advantage of liquid reference standards is that they can be used with the supplied cell
to check any liquid measuring instrument, not just Lovibond® instruments. This means the
operator can verify inter-instrument agreement between different instruments. At the same
time, it is possible to check the application and how the samples are being prepared and
presented to the instrument, in other words, make sure there are no finger prints on the cell
or, in the case of heated samples, no thermal currents in the sample liquid.
Confidence in Colour Measurement
For regular conformance checking, Certified Reference Solutions are supplied with full
traceability to internationally recognised standards, either ISO/IEC 17025:2000 (ASTM Color,
Saybolt and Gardner Colour) or the ISO 9001:2000 quality system (Pt-Co Units). This confirms
that they have been manufactured and inspected under the control of The Tintometer Ltd’s
ISO 9001:2000 quality system.

Cells made from Optical Glass conform to British Standard 3875.
Borosilicate glass has a very low coefficient of thermal expansion, making it resistant
to thermal shock and therefore less likely to crack when heated and cooled. It is
recommended for use with hot samples.

The transmission range for Extrasil ES quartz is from 170 - 2,500nm. In this range,
Extrasil ES quartz transmits at over 80%.

Special Cells
Lovibond® Special Cell Department is available for making any cell to customers’ own requirements providing that such a cell is technically possible.
Quotations for special cells will be sent on receipt of drawings or sketches giving relevant details of material and exact measurements.
Packaging
All Lovibond® Spectrophotometer cells are supplied in attractive presentation cases. Other types of cells are suitably packed and shipped according to size
and quantity ordered.
Care and Cleaning of Cells
It is important to recognise that Lovibond® optical cells are delicate scientific apparatus and great care should be taken in cleaning them before and
after use. Contamination by dirt can lead to relatively large instrumental errors. The cell windows can be stained by leaving the cell filled with certain
samples. The following methods of cleaning are recommended.:
1) The cell should be brought to the boil slowly from cold and boiled for 15 minutes in a 2% solution of detergent in distilled water, rinsed thoroughly
in distilled water and finally in ethanol before allowing to dry. Any deposit on the faces should be removed by washing in 5% hydrochloric acid before
rinsing in water.
2) Staining can be removed by immersing the cell in freshly prepared chromic acid and leaving overnight. The cell should then be rinsed and dried per
above. Cells should not be allowed to dry out at any intermediate stage.
NEVER attempt to clean a cell by pushing cloth down inside it because the leverage may crack the face. When the cells are not in use, store in fitted
cases so as to protect the windows from accidental damage.
