Gilson Company, Inc. products

3in (76mm) diameter ASTM E11 Test Sieve has stainless steel woven-wire cloth with 3/8in (9.5mm) openings and full-height stainless steel frame. The overall height is 1-3/4in and the stacked height is 1-1/8in.

Gilson Tapping Sieve Shakers have a researched-based sieving action that produces sharp, repeatable separations quickly over a broad range of particle sizes and material types. The Gilson-engineered sieving action results from perfect circular rotation of the sieve stack plus vertical two-way tapping at 48 taps per minute. These high-capacity shakers can hold as many as twenty sieves, depending on model and sieve frame dimensions.

Gilson`s Orbital Sieve Shakers are portable, easy to use, and outperform comparably priced sieving equipment. They are used in particle size testing of mineral aggregates and for sieve gradations of many other free-flowing granular materials. These cost-effective 1/4hp units are widely accepted by state transportation departments for highway materials testing.

Gilson Silent Sifters are the newest laboratory sifter models that reflect today`s emphasis on noise reduction and worker protection in the laboratory environment. They significantly reduce operational noise levels with no loss of particle sizing accuracy and performance. Gilson`s proprietary silencing technology has resulted in units with noise levels 7–18dB quieter than standard rotary sifters.

Gilson Testing Screens are ideal for particle size determinations on large samples of aggregate, slag, ores, and other coarse materials. Batch sizes up to one cubic foot (28.3L) or more can be processed into six fractions in as little as six to ten minutes, depending on the material type.

Gilson Test-Master Testing Screens deliver accurate particle size separations for large samples and are ideal for coal, coke, ore, and many other dry, granular materials. Standard vibration characteristics are designed for coarse materials of mid-range density, such as limestone or gravel aggregates.

Gilson Porta-Screen has long been accepted for quality control of construction aggregates. The Porta-Screen models are built for performance and durability, yet are light enough to be portable. It is optimized for separation of mineral aggregates in the 2in (50.8mm) to No.16 (1.18mm) range, but are capable of separating materials to No.200 (75μm) sizes.

Gilson Universal Splitters are the most versatile sample dividers available for true representative specimens when reducing samples. Each splitter features our exclusive, adjustable chute system and proprietary lever-release hopper. The lever-release hopper exclusive feature assures top accuracy when reducing bulk materials. These features result in the most accurate and precise sample reduction.

Universal Mini-Splitters are the smallest of Gilson’s exclusive Universal Splitter designs, making them an excellent choice for powders and granular materials with top sizes less than 0.25in (6.4mm). Portable benchtop models are identical in structure and can easily be positioned anywhere. 

Fixed Chute Splitter assists in rapid and accurate splitting and mixing of granular materials up to 1.125in (28.6mm) topsize. This model is based on our original SP-1 Universal Sample Splitter (1.0ft^³ Hopper Capacity) design and features ten fixed-width chutes, each 2.25in (57.2mm) wide. Fixed Chute Splitters feature the original Gilson-designed lever-release hopper with 1ft^³ (28.3L) capacity to allow equal sample distribution. This rugged floor model splitter has a rugged welded and bolted steel frame with a painted and baked finish. Two steel sample pans are included.
