Product description

Topas EMS 755 electromagnetic sieve shaker for dry and wet particle size analysis, with four analytical 50 µm sieves and amplitude control.

The Topas EMS 755 electromagnetic sieve shaker is a laboratory sieve shaker for dry powders and wet suspensions. It supports fine particle size analysis, particle fractionation and analytical sample preparation.

The unit includes four analytical 50 µm sieves. Adjustable amplitude from 0% to 100% allows the oscillation intensity to be set for the sieving process. Horizontal and vertical sieve clamp oscillation supports particle separation.

The used unit operates on 230 V AC and has an integrated tripod clamp for a 15 mm stand rod. The main unit measures 140 × 70 × 270 mm and weighs approximately 3.1 kg without the tripod or 3.7 kg with the tripod.

The Topas EMS 755 is an electromagnetic sieve shaker for laboratory particle size analysis of dry powders and wet suspensions. It is designed for fine particle separation, including ultra fine particles below 20 µm.

Unit configuration

  • Four analytical 50 µm sieves included
  • Horizontal and vertical oscillation of the sieve clamp
  • Adjustable amplitude from 0% to 100%
  • Integrated tripod clamp compatible with a 15 mm stand rod
  • Mountable on a laboratory stand

Technical specifications

  • Mechanical oscillation frequency: approximately 100 Hz
  • Sieve clamp: analytical sieves, approximately 75 mm diameter
  • Power supply: 230 V AC
  • Power consumption: less than 100 W
  • Operating temperature: 10 to 50 degrees C
  • Main unit dimensions: 140 × 70 × 270 mm
  • Weight: approximately 3.1 kg without tripod
  • Weight: approximately 3.7 kg with tripod

The used Topas EMS 755 is suited to particle size analysis, fine powder sieving, suspension separation, filtration testing, media testing and analytical sample preparation.

What these specifications mean

The adjustable amplitude controls the sieving force applied to the sample. This supports adjustment for dry powder sieving, wet suspension separation and fine particle fractionation.

The supplied 50 µm analytical sieves establish a fine screening aperture for particle size analysis. The approximately 75 mm sieve diameter defines the compatible analytical sieve format.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
