Retsch® Knife Mill GRINDOMIX GM 300 Compact Benchtop Model | 220-230V, 50/60 Hz

The RETSCH GRINDOMIX GM 300 is a professional laboratory knife mill designed for fast, reproducible homogenization of large sample volumes. It’s ideal when you need to turn heterogeneous or bulky food, plant, or biological samples into fully mixed, analytical‑grade material in seconds. Its large grinding chamber, robust knives, and flexible settings make it well suited for varied workflows — whether doing dry or wet grinding, or even cryogenic processing using dry ice.

Key Features

• Large grinding chamber (~ 5000 mL) capable of handling batch/feed volumes up to ~ 4500 mL with the standard lid; ~ 4000 mL with the gravity lid.
• Powerful motor: continuous 1.1 kW with short‑term peaks up to ~3 kW to handle tougher or wet/oily samples. 
• Adjustable speed: digitally controllable from ~ 500 to 4,000 min⁻¹ in 100 min⁻¹ increments.
• Digital timer: set grinding durations from about 5 seconds up to ~3 minutes.
• Stores up to 10 Standard Operating Procedures (SOPs) for repeatability across runs.
• All parts contacting the sample (knives, containers, lids) are autoclavable, facilitating cleaning and preventing cross‑contamination.
• Gravity lid option: automatically adjusts the chamber volume during grinding; improves homogenization and helps contain sample material.
• Supports both dry and wet grinding; also offers a specialized lid for cryogenic (dry‑ice) grinding for tough or elastic materials.
