Technical Specifications

The PULVERISETTE 6 classic line is a single-station planetary ball mill from FRITSCH, built for labs that need high-energy comminution in a small footprint. One grinding bowl mounts on the main disk, and the mill reaches 650 rpm with centrifugal acceleration up to 29 g. Hard, medium-hard, brittle, and moist materials can be ground dry, in suspension, or in inert gas, with loss-free results below 1 μm. The specifications below describe the standard configuration; bowl size, bowl material, gassing lids, and EASY GTM components are chosen separately for each application.

Pre-installation Requirement:
Place the mill on a rigid, level bench with enough clearance to open the grinding chamber fully. Leave space around the unit for the cooling fan airflow. Connect to a grounded power supply matching the nameplate rating. Confirm room temperature and ventilation suit extended grinding runs, and complete the FRITSCH installation and safety briefing before first use.

Why This Mono Mill Fits Labs With Limited Bench Space

A single grinding station sounds like a limitation until you look at what it buys. The PULVERISETTE 6 classic line planetary ball mill puts one bowl on a main disk that spins to 650 rpm, with adjustable imbalance compensation that keeps single-bowl operation smooth. You get high-energy impact grinding in a unit that takes up far less bench space than a two-station mill, and you get it with the simplest bowl handling in the classic line.

The capacity range is wider than the footprint suggests. A 500 ml bowl handles larger batches, while 45 ml and 12 ml bowls cover small sample amounts where every milligram counts. An adapter lets you run two smaller bowls at once, so the same instrument can process a duplicate pair when the method calls for it.

For buyers sourcing through OS4U, the decision usually comes down to bowl material and whether gassing or EASY GTM monitoring belongs in your workflow. The FRITSCH PULVERISETTE 6 classic line page lists the full accessory range and application notes.

Key Benefits

High-energy grinding in a small footprint

The PULVERISETTE 6 classic line laboratory mill reaches 650 rpm and 29 g acceleration from a single grinding station. That is enough force for loss-free results below 1 μm in hard, medium-hard, and brittle materials, without the bench space a two-station mill demands.

Bowl clamping you can trust

The Safe-Lock System, supplied with a torque wrench, clamps the grinding bowl securely with no guesswork. Combined with the easily adjustable imbalance compensation, single-bowl runs stay stable and reproducible.

Timer control down to the second

The electronic timer adjusts to ±1 second and supports programmable interval and pause times plus a reversing feature. When a method depends on exact grinding duration, you are not estimating it.

Cooling that supports long runs

A built-in fan cools the grinding chamber during extended grinding. Heat-sensitive samples stay within a narrower temperature window, and long runs do not turn into a heat management problem.

Controls that stay readable and protected

The IP65 membrane keyboard is splash-proof and positioned where you can see it even with the grinding chamber open. Grinding parameters remain visible and adjustable throughout the run, and the chamber wipes down without drama.

Optional pressure and temperature data

Adding the EASY GTM classic line system turns the mill into an analytical measuring system, logging gas pressure and temperature inside the bowl during grinding. For mechanochemistry and alloying work, that data is often the difference between a result and a documented result.

Solving the Problems That Slow Sample Prep Down

Struggling with limited bench space? One grinding station and a compact housing mean the mill fits where a two-station unit will not. Adjustable imbalance compensation keeps the single-bowl setup running smoothly.

Getting inconsistent results between runs? The regulated drive, toothed-belt transmission, second-accurate timer, and programmable interval and pause times give every run the same starting conditions. Safe-Lock clamping removes bowl seating as a variable.

Worried about heat during long grinds? The built-in chamber fan runs through extended grinding, keeping temperature under better control than an uncooled chamber.

Need to grind small sample amounts? Bowls from 500 ml down to 12 ml cover the range, and an adapter allows two smaller bowls in one run when you need a duplicate.

Concerned about contamination from abrasion? Grinding bowls and balls come in six materials, so you can match the bowl to sample hardness and acceptable contamination limits.

Running oxygen-sensitive or alloying work? Inert gas grinding with gassing lids and EASY GTM pressure and temperature monitoring are both supported on this platform.
