Chromatographic Paper (110x140 mm)
Chromatographic Paper (110x140 mm) (Product Code: SCI-621/271) is a rectangular chromatography sheet used to separate the coloured components of inks, food dyes and plant pigments by paper chromatography in school and college chemistry and biology classes. Each sheet measures 110 × 140 mm, a convenient size for developing in a beaker or small jar. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, together with the glassware a chromatography practical needs.

What Is Chromatography Paper Used For?
For paper chromatography in school, students draw a pencil baseline a short distance above the lower edge, spot the sample on it with a capillary tube and stand the sheet in a container whose solvent sits below the line. As the solvent climbs, each dye travels a different distance, and the class calculates Rf values by dividing the distance moved by a spot by the distance moved by the solvent front.
Typical experiments include separating black marker ink, checking the colours in sweets or food colouring, and separating chlorophyll and carotenoid pigments from leaf extracts with a suitable solvent. Handle the sheet by its edges, mark it only in pencil and let it dry flat before measuring. Several spots can be run side by side on one sheet so that samples are compared under identical conditions.
Supplier
Jain Scientific Equipments Private Limited, trading as ScienceLab, sources this chromatography paper and supplies it to schools, colleges and dealers, often with capillary tubes, solvents and glassware so that a whole practical arrives in one consignment.

Frequently Asked Questions
What size is Chromatographic Paper (110x140 mm)?
Chromatographic Paper (110x140 mm) is a rectangular sheet measuring 110 × 140 mm. The size suits developing in a beaker or small jar and leaves room for several sample spots along one baseline for side-by-side comparison.
What experiments use Chromatographic Paper (110x140 mm)?
Chromatographic Paper (110x140 mm) is used for paper chromatography practicals such as separating the dyes in black ink or food colouring, comparing felt-tip pens in simple forensic exercises and separating leaf pigments. Students then measure Rf values from the dried sheet.
How do you calculate Rf values on chromatography paper?
To calculate an Rf value on Chromatographic Paper (110x140 mm), divide the distance travelled by the centre of a spot by the distance travelled by the solvent front, both measured from the pencil baseline. The result is always less than one.
Which solvent should be used with this chromatography paper?
The solvent for Chromatographic Paper (110x140 mm) depends on the sample: water separates many water-soluble inks and food dyes, while leaf pigments need an organic solvent mixture chosen by the teacher. Always keep the solvent level below the baseline.
How many sheets come in a pack of Chromatographic Paper (110x140 mm)?
The number of sheets per pack and the paper grade of Chromatographic Paper (110x140 mm) are not stated on this listing. Ask us through the contact page and we will confirm the pack details with your quotation.
Who supplies Chromatographic Paper (110x140 mm) SCI-621/271?
Chromatographic Paper (110x140 mm) SCI-621/271 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools, colleges, laboratories and dealers in India and international markets.
