What Is Qualitative Filter Paper Used For?
Qualitative filter paper holds back solid particles while the liquid runs through, so it is used wherever students need to separate an insoluble solid from a solution: removing sand or chalk from water, recovering a precipitate formed in a reaction, clearing a cloudy solution before crystallisation, and preparing clear test solutions for qualitative salt analysis in class 11 and 12 chemistry. Separation of mixtures by filtration appears in middle-school science from class 6 onwards, so this is one of the most-used consumables in school chemistry lab equipment. Because it is a qualitative grade, it is meant for separating and observing; gravimetric work, where the residue is ignited and weighed, uses ashless quantitative paper instead.
For gravity filtration, fold the paper in half and then into quarters, open it into a cone with three layers on one side, and seat it in a funnel; wet it with a little of the solvent so it sticks to the glass. Keep the top of the paper just below the funnel rim, pour the mixture down a glass rod, and rinse the residue with a wash bottle. A fluted (pleated) fold gives faster filtration when only the filtrate is wanted.
What to Specify When Ordering
- Size — this 12.5 cm paper, or the 90 mm or micro-scale papers for smaller funnels and kits.
- Pack count and number of packs — the listing does not give the pack size, so state how many papers you need in total.
- Funnels and stands — glass funnels, funnel holders and stirring rods can be added to the same enquiry.
Frequently Asked Questions
What is this filter paper used for?
Separating precipitates and impurities from liquids and preparing clear solutions for qualitative analysis. It is a student-grade paper for routine teaching filtrations.
What size is it?
12.5 cm, which is 125 mm. Fold it into a cone to suit your funnel; the paper should sit just below the funnel rim.
Can it be used for quantitative (gravimetric) analysis?
It is listed as a qualitative paper. Gravimetric methods that ignite and weigh the residue need an ashless quantitative grade, which this listing does not cover.
What is its retention or filtration speed?
These values are not stated in this listing. If your method needs a particular retention or speed, give it in your enquiry so JLab can advise.
How many papers are in a pack?
The listing does not state the pack size. Ask JLab to confirm the number per pack in the quotation.
What should an export enquiry include?
The quantity, the destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling instructions, and the tender reference if applicable.
Who makes this filter paper?
Jain Laboratory Instruments Pvt Ltd (JLab), which sells it under the JLab brand from its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of school and college lab equipment and consumables, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This JLab-brand filter paper comes from the company’s own works, not from a trader, so schools, colleges, dealers and importers order it factory-direct; packs are visually checked before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Indonesia in Southeast Asia, Namibia in Southern Africa, Turkmenistan in Central Asia, Nepal in South Asia and Poland in Eastern Europe. Tender details are on the JLab lab tenders page.
Filtration Apparatus
- Funnel Glass — a plain conical borosilicate glass funnel to hold the folded paper.
- Funnel Holder — a polypropylene holder that clamps funnels on a stand rod.
- Stirring Rod Glass — a glass rod for stirring and for pouring the mixture into the filter.
- Wash Bottles — a squeeze bottle with a delivery tube for rinsing the residue on the paper.
- Filter Pump — a water-driven vacuum pump in borosilicate glass or plastic for faster suction filtration.
More school consumables and apparatus are in the School Lab Equipment range.
