BO-300ESS Laboratory Electromagnetic Sieve Shaker for Particle Size Analysis
The LVOBO BO-300ESS Electromagnetic Sieve Shaker is designed for laboratory particle size analysis, particle classification and sieve residue testing. It helps research teams and quality control laboratories assess powder and granular samples using selected test sieve openings.
Its electromagnetic drive generates sample movement without conventional cam or eccentric mechanical impact transmission. Operators can adapt the sieving procedure to the material, retain established settings and collect several size fractions in one run. Touchscreen operation and recipe recall support routine inspections, formulation comparisons and recurring laboratory tests.

It is a laboratory instrument that separates particulate samples using test sieves. The retained fractions can be collected and weighed to support particle size assessment and sample comparisons.
The electromagnetic drive moves the sieve stack. Test preparation remains important: choose the opening sequence, sample quantity and operating settings to match the purpose of your laboratory procedure.
The BO-300ESS uses electromagnetic actuation instead of conventional cam or eccentric mechanical transmission. For procurement, compare the available adjustments, sieve compatibility and suitability for the samples you intend to test.
Yes. Stored parameter sets let operators return to an established setup. Comparable tests also depend on sample preparation, sample loading and sieve condition, even when machine settings are recalled.
Sample properties and testing requirements determine the configuration. If your laboratory method specifies openings or fraction boundaries, share those details so LVOBO can review the selection against the intended test.
Send your sample material, target particle size, sample quantity and required sieve diameter to LVOBO. Include any testing requirements or specified sieve openings so we can review the configuration and prepare a quotation.
