Riffle Sample Divider (Product Code: SLE/AG/12) is a chute-type sample splitter used to divide granular material into two representative halves in aggregate, soil and mineral testing laboratories. Its sheet metal box on legs carries a series of equal-width chutes that discharge alternately into separate pans, and it is offered in sizes from 7 mm to 75 mm. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM laboratory equipment manufacturer in India, at its own factory in Ambala.

The sample is spread evenly in a scoop or pan the same width as the riffle and poured steadily along the full length of the chutes. Because neighbouring chutes point in opposite directions, every other slice of the stream goes to one pan and the rest to the other, so each pan receives a fair half. One half is kept and the process is repeated with it until the portion reaches the mass the test needs. The steep chutes keep material moving so that fines and damp particles do not hang up inside.
Choose the size according to the largest particle in your material, since stones must pass freely through the chutes; labs that test both sand and coarse aggregate often keep two sizes. From aggregate work to mineral studies and seed or grain analysis, the riffle is the everyday tool for fair sub-sampling and standard educational laboratory equipment in India's civil engineering colleges. Tap the box lightly after pouring so no grains stay behind, and brush the chutes clean between samples.
Jain Scientific Equipments Private Limited produces the Riffle Sample Divider under the ScienceLab name as its OEM (original equipment manufacturer). Every size is made at the company's own licensed factory at Saha, Ambala, Haryana, India, so laboratories, contractors, dealers and importers buy directly from the maker instead of a trading house. Need extra pans or a second size later? Ask us and the manufacturer will quote it; our profile page has more about the company.

How does the Riffle Sample Divider split a sample?
The equal-width chutes of the Riffle Sample Divider send alternate slices of the poured material in opposite directions into separate pans, giving two matching halves; repeating the pass with one half reduces the sample further.
Which sizes of Riffle Sample Divider are available?
The Riffle Sample Divider is offered in a range of sizes from 7 mm to 75 mm. Tell us the largest particle size in your samples and we will suggest a suitable size for your laboratory.
Can one Riffle Sample Divider handle both sand and coarse aggregate?
Only if the chutes of the Riffle Sample Divider are wide enough for the coarsest stones without being too coarse to split fine material fairly, which is why many laboratories keep a smaller and a larger size.
What is the Riffle Sample Divider made of?
The Riffle Sample Divider is a sheet metal box mounted on legs, with a series of equal-width chutes built into the box that are steep enough to let material flow rapidly into the pans.
Are collecting pans supplied with the Riffle Sample Divider?
The Riffle Sample Divider discharges into separate pans; please confirm which pans are included for your chosen size when you request a quotation, so the set arrives ready for use.
Who manufactures the Riffle Sample Divider?
The Riffle Sample Divider is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct in every listed size.
How do I avoid bias when splitting with the Riffle Sample Divider?
Pour slowly and evenly along the full length of the Riffle Sample Divider chutes, never from one end, and alternate which pan you keep between passes so that neither side is favoured.
