Colorimeter Photo Digital
Product Code : LSK-CL-10051
Colorimeter Photo Digital (SKU LSK-CL-10051) is a digital photo colorimeter that finds the concentration of a known constituent in a solution by comparing its colour with that of a standard, using specific reagents. It reads samples in test tubes, covers 400–700 nm with an 8-filter disc and shows transmission or absorbance. School chemistry labs, college analytical practicals and water-testing classes use it. Science Lab Supplies supplies the instrument from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The instrument selects its wavelength with a rotating disc carrying 8 filters across 400–700 nm. An automatic shutter stops light reaching the sensor between readings, an auto-zero function sets the blank, and soft-touch membrane keys control the two photometric modes: 0–100 % transmission and 0–1.99 absorbance.

Applications and Experiments for the Photo Colorimeter
The colorimeter is used for quantitative colour-based analysis. Students prepare a set of standards, record absorbance at the filter that matches the colour of the solution, draw a calibration line and read the unknown against it, which is the practical basis of the Beer–Lambert law.
- Class 11–12 chemistry projects: concentration of coloured solutions such as copper sulphate or potassium permanganate.
- B.Sc. analytical chemistry: verifying the Beer–Lambert law and choosing the filter of maximum absorbance.
- Environmental and water-testing courses: reagent-based tests for dissolved constituents.
- Biochemistry and life-science practicals: colour reactions for estimating proteins or sugars.
Standard Scope of Supply
The Colorimeter Photo Digital is supplied as a single instrument with its built-in 8-filter disc, as described above. Custom-formulated reagents are optional and quoted separately; shelf life depends on the chemical, its grade and storage conditions, so ask us for the expiry date of the batch you are quoted.
Packing, MOQ and Lead Time
You may request a quotation for one colorimeter or for several analytical benches. It will state packing, delivery time and price for the requested quantity, and test tubes, volumetric glassware or other chemistry lab instruments can be priced on the same quotation.
Science Lab Supplies is an Importer-Exporter Code holder and can therefore ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Questions and quote requests go through the contact page; the enquiry cart collects multiple items, and the lab tender page covers tender purchases.
Frequently Asked Questions
What does a photo colorimeter measure?
It measures how much light of a chosen colour a solution transmits or absorbs, and from that the concentration of the coloured constituent is found by comparison with standards.
Does this model use cuvettes or test tubes?
It uses test tubes only, so samples are read directly in tubes rather than in square cuvettes.
Who supplies the Colorimeter Photo Digital?
Science Lab Supplies supplies it from Ambala, India, and can quote it together with glassware and other instruments for an analytical lab.
How is it different from a spectrophotometer?
The colorimeter uses 8 fixed filters across 400–700 nm, while a spectrophotometer selects wavelengths continuously. The colorimeter suits routine teaching and reagent-based tests.
