Laboratory Separators for Particle Size Analysis and Sieving
Laboratory separators in this category are primarily used for sieve-based particle separation, helping teams classify material fractions, verify particle size distribution and prepare samples for further testing. Vibratory sieve shakers are commonly used in quality control, research and production support where powders, granules or suspensions need to be separated through stacked test sieves.
- Fritsch Sieve Shakers: Select Fritsch ANALYSETTE 3 PRO or SPARTAN models for controlled dry or wet sieving in laboratory particle analysis workflows.
- Particle Classification: Separate solids, powders, granules and selected suspensions into defined size fractions for QC or analytical review.
- Dry and Wet Sieving: Choose suitable configurations for dry bulk solids, fine powders, wet sieving or suspension-based sample work.
- Quality Control Support: Use laboratory separators for incoming material checks, outgoing product verification and reproducible particle size distribution testing.
How to Choose Laboratory Separators and Sieve Shakers
Selection should begin with the material type, sample quantity, target particle size range, sieve diameter and whether the workflow requires dry or wet sieving. Fritsch notes that its ANALYSETTE 3 PRO and SPARTAN systems support dry and wet sieving, separating and fractioning, with the PRO model adding automatic amplitude control and programme selection for reproducible laboratory work.
- Sample Type: Match the separator to powders, granules, coarse solids, fine particles or suspensions.
- Sieve Diameter: Confirm compatibility with the test sieve diameter and number of sieves required for the method.
- Particle Size Range: Select equipment that supports the target measurement range and mesh sizes required for your test procedure.
- Reproducibility: Consider amplitude control, programme storage and evaluation software where results need to be repeatable and documented.
- Accessory Needs: Review sieve stack tensioners, clamping lids, test sieves, sieve pans and wet sieving accessories before procurement.

Frequently Asked Questions
What are laboratory separators used for?
Laboratory separators are used to separate, classify or fraction samples by particle size, commonly through sieve-based workflows for powders, granules, solids and suspensions.
What is a vibratory sieve shaker used for?
A vibratory sieve shaker moves a stack of test sieves so particles pass through mesh openings according to size, allowing laboratories to measure particle size distribution and retained fractions.
How do I choose between dry and wet sieving?
Dry sieving is commonly used for free-flowing dry solids. Wet sieving is useful where fine powders agglomerate, samples are suspensions or material needs liquid-assisted separation through the sieve mesh.
