Technical Specifications

The ANALYSETTE 3 PRO is an electromagnetic vibratory sieve shaker from FRITSCH, built for fast quantitative particle size distribution of solids and suspensions. The sieve stack oscillates vertically under microprocessor control, with AMPCONTROL holding a constant amplitude so results stay reproducible under DIN 66165-1. It handles sample quantities up to 2 kg across a measurement range from 20 μm to 63 mm, in dry or wet sieving mode. The specifications below cover the standard unit; test sieves, clamping lid, and sieve pan are ordered separately.

Pre-installation Requirement:
Place the shaker on a rigid, level bench that will not transmit vibration to adjacent instruments. Leave clearance above the unit for loading and removing the sieve stack. Connect to a grounded power supply matching the nameplate rating. If AUTOSIEVE is used, arrange a balance connection and install the software before the first evaluation run.

Why This Sieve Shaker Belongs in a Quality Lab

Sieve analysis fails quietly when amplitude drifts. A stack that shakes slightly harder on Monday than it did on Friday produces a particle size distribution that looks plausible and cannot be defended. The ANALYSETTE 3 PRO vibratory sieve shaker addresses that directly: AMPCONTROL holds a constant amplitude, the RS232 interface lets you compare set and actual amplitude online, and the same settings can be stored in one of ten programmes and recalled exactly.

The range is broad for a bench instrument. From 20 μm to 63 mm, with up to 2 kg of sample and up to ten sieves in one stack, it covers incoming raw material checks and outgoing product release on the same machine. Wet sieving with the two-nozzle lid handles suspensions that would blind a dry stack.

For buyers sourcing through OS4U, the practical questions are sieve sizes, the clamping lid, and whether TorqueMaster tensioning belongs in your workflow. The FRITSCH ANALYSETTE 3 PRO page lists the full accessory range.

Key Benefits

Amplitude that stays where you set it

AMPCONTROL keeps the oscillation constant throughout the run, which is what makes results reproducible under DIN 66165-1. The ANALYSETTE 3 PRO laboratory sieve shaker also compares set and actual amplitude online through the RS232 interface, so drift shows up as data rather than as a questionable result.

Ten programmes, recalled exactly

Up to ten individual sieve programmes can be stored with amplitude, sieving time, intermittent mode, and sieving type. A method validated once can be rerun by any operator without re-entering parameters.

Wet and dry sieving on one platform

The wet sieving lid with two rotation nozzles handles suspensions and materials that agglomerate in dry mode. Switching between dry and wet is a configuration change, not a second instrument purchase.

Documentation that supports ISO 9001 use

AUTOSIEVE connects to a laboratory analysis balance, performs differential weighing, and evaluates the result automatically. The unit is designed to serve as a calibratable and validatable test instrument in test equipment monitoring per DIN EN ISO 9001.

Faster runs on bulky material

Intermittent mode reduces sieving time for low-density, voluminous samples by interrupting the oscillation cycle. Optimised power consumption also keeps the sieving system from warming during longer runs.

One bench unit, two jobs

The shaker converts to the Vibratory Micro Mill PULVERISETTE 0 for grinding and homogenising small samples, with a cryo-box option for liquid nitrogen work. Labs that sieve and mill small quantities can cover both on one base unit.

Solving the Problems That Slow Sieve Analysis Down

Struggling with results that shift between runs? Constant amplitude through AMPCONTROL, stored programmes, and optional TorqueMaster tensioning remove the three variables that most often cause drift: amplitude, parameters, and stack clamping force.

Spending too long on each sieve stack? Up to ten sieves run in one cycle, with up to five sieving operations in parallel. Intermittent mode shortens runs on low-density material.

Getting blinded sieves on fine powders? Wet sieving with the two-nozzle lid keeps fine material moving and clears mesh openings that dry sieving cannot.

Reconciling weights and calculations by hand? AUTOSIEVE handles differential weighing with a connected balance, stores empty sieve weights, and produces the evaluation and documentation automatically.

Worried about audit evidence? The unit is built for use as a calibratable and validatable test instrument under ISO 9001 test equipment monitoring, with programme recall and amplitude records to support it.

Need to grind small samples too? Conversion to the PULVERISETTE 0 covers grinding and homogenising of 1–10 ml samples, with cryo-grinding available.
