Gilson Laboratory Split-O-Matic® Splitters

Gilson Laboratory Split-O-Matic Splitters are ideal for quickly and accurately reducing large samples through multiple stages with a single pass.

Exclusive Gilson threestage design allows the user to select sample fractions of 1/2, 1/4, or 1/8 of bulk sample. A selection lever sets internal sample fraction positions, directing selected fraction to the sample pan and the balance to the reject pan. V-bottom chutes precisely align material flow for more accurate divisions.

Laboratory Splitters are well-suited for aggregates, sand, gravel, ores, coal and coke or other free-flowing granular materials up to 2in (51mm) topsize. Laboratory Splitters have heavy, welded-steel construction with painted and baked finish. Sample hoppers have a gate-release mechanism for greater control of sample dividing. Front panel doors latch shut for superior dust control, and open wide for easy cleaning. Sample pans are included, and are size-matched to hopper capacity. Bottom flange is suitable for anchored or freestanding lab use. Standard models feature three stages of 45° chute slopes, suitable for most materials. Steeper 60° chute slope models are recommended for low specific gravity materials such as coal or coke, or materials with a large fraction of fines. The 60° Laboratory Splitters are approximately 20% taller, slightly heavier, and are ordered by adding a “C” suffix to model numbers.

For best results, choose a splitter with chute width at least twice that of the material’s topsize to avoid bridging over chute openings. For coal or coke, or for materials with oblong pieces, 3 to 4 times topsize is recommended. Any Laboratory Splitter can be custom-ordered with special larger hopper and sample pans if needed. Custom models may also be ordered with four or more chute stages for sample fractions smaller than 1/8.

These higher-capacity units process bulk samples of granular materials into small fractions for efficient preparation of test specimens. Select from a range of models with varying chutes per stage, sample fractions, chute bar width, chute slope and maximum particle size to suit your application.
