Filter Papers, Litmus & pH Strips
Filter papers, litmus paper, and pH indicator strips are consumables relied on daily across water treatment facilities, food and beverage testing labs, pharmaceutical quality control departments, environmental monitoring companies, and school laboratories throughout South Africa. SmartLabs stocks red and blue litmus paper, full-range pH indicator strips, Ahlstrom-Munksjö qualitative filter papers in multiple grades, chromatography paper, and cobalt chloride indicator paper, with prices from R27 and fast dispatch from Boksburg.
How to choose the right paper or strip
For routine pH screening in water testing or food production, full-range 0-14 pH indicator strips give a quick, reliable reading without any equipment. For filtration in a professional lab, match the filter paper grade to the particle size you are separating: grade 601 suits general filtration, grade 642 provides faster flow for coarser particles, and grade 631 sits between the two. Chromatography paper is specifically designed for separation and identification work and is not interchangeable with general filter paper.
Frequently asked questions
Do you stock filter papers for industrial or pharmaceutical laboratories?
Yes. SmartLabs carries Ahlstrom-Munksjö qualitative grades 601, 631, and 642 in a range of diameters from 35mm to 150mm, suitable for professional laboratory and quality control applications.
What is the difference between litmus paper and pH strips?
Litmus paper indicates whether a solution is acidic or alkaline. pH test strips give a precise numeric reading from 0 to 14, which is more useful for QC records and quantitative reporting.
Can I order filter paper in bulk?
Yes. Our larger pack sizes and bulk pricing options are available on request. Contact us for volume pricing.
