Blaine Fineness Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-M-8895
Jlab Export is a leading Blaine Fineness Apparatus Manufacturer,and suppliers in India
Blaine Fineness Apparatus (code EL-M-8895) measures the fineness of cement by air permeability: air is drawn through a compacted bed of powder in a stainless steel cell of 12.70 mm bore, and the fall of dibutyl phthalate in a glass U-tube manometer is timed. Cement works, quality-control rooms and college laboratories use it for routine fineness checks. JLab makes the apparatus in Ambala, India.

What Is the Blaine Fineness Apparatus Used For?
It is used to find the specific surface of Portland and blended cements and similar fine powders in cement plants, construction-materials laboratories and civil engineering courses. A weighed sample is compacted in the cell between filter-paper discs with the plunger, air is drawn through it with the rubber bulb, and the time the manometer liquid takes to fall over a set distance is recorded. Keep the perforated disc clean and dry between tests.
Frequently Asked Questions
What does the Blaine Fineness Apparatus measure?
It gives the fineness of cement as specific surface, worked out from how long a fixed volume of air takes to pass through a compacted bed of the sample.
Which liquid goes in the manometer?
Dibutyl phthalate. It fills the glass U-tube manometer, which carries a ground joint, a stopcock and a rubber bulb assembly for drawing air through the cell.
What size of filter paper does the cell take?
Discs of 12.70 mm diameter, matching the 12.70 ± 0.10 mm bore of the stainless steel cell; one disc sits below the sample and one above it.
Who makes the Blaine Fineness Apparatus?
JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, makes it in Ambala, Haryana, and sells it factory-direct to cement plants, colleges and distributors.
OEM Manufacturer
Jain Laboratory Instruments Pvt Ltd trades as JLab and has built laboratory apparatus on Hargolal Road, Ambala, since its incorporation in 2017. The cell, plunger and perforated disc all come from the same maker, so replacement parts and repeat units are quoted by the factory that produced the original set. JLab exports worldwide, including to Italy in Southern Europe, Panama in Central America and the Caribbean, Namibia in Southern Africa and Oman in the Middle East.
