Colorimeter Photo Digital
Product Code : LSK-CL-10051
Colorimeter Photo Digital (SKU LSK-CL-10051) is a digital photo colorimeter that finds the concentration or quantity 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. The instrument reaches schools, colleges, training institutes, tender contractors and distributors through Science Lab Supplies, its supplier in Ambala, India.
Specifications
The colorimeter's optics, modes and controls each take a row in the table. To summarise: test-tube sampling, a rotating disc of 8 filters over 400–700 nm, an automatic shutter in front of the sensor, auto zeroing, soft-touch membrane keys, and readings of 0–100 % transmission or 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, read in ordinary Test Tubes.
- B.Sc. analytical chemistry: verifying the Beer–Lambert law and choosing the filter of maximum absorbance.
- Environmental and water-testing courses: reagent-based tests, compared with visual matching in a Nessler Cylinder.
- 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. Custom-formulated reagents are optional and quoted separately; shelf life depends on the chemical, its grade and storage conditions; 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. To price an analytical bench, state the number of instruments and any reagent needs on the contact page, or combine the colorimeter with glassware in the enquiry cart; universities and departments tendering for instruments can consult the lab tender page.
Frequently Asked Questions
What does a photo colorimeter measure?
It measures how much light of a chosen colour a solution transmits or absorbs. From that reading, the concentration of the coloured constituent is found by comparison with standard solutions prepared with specific reagents.
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. Matched, clean tubes give the most consistent readings from one sample to the next.
Who supplies the Colorimeter Photo Digital?
Science Lab Supplies in Ambala, India acts as supplier for this colorimeter and can quote it with glassware, pH meters and other instruments when an analytical laboratory is being set up.
How is it different from the visible spectrophotometer?
The colorimeter uses 8 fixed filters across 400–700 nm. The Visible Spectrophotometer supplies monochromatic light over 330–1000 nm with a 10 nm bandwidth, so it suits work needing specific wavelengths.
