Silverson Mixer with Stand

• Emulsification and homogenisation in the food, pharmaceutical, and cosmetic industries.
• Disintegration and dissolution of solids into liquids.
• Mixing and blending of high-viscosity products.
• Aeration and de-aeration processes for various formulations.

Typical capacity

For this class of Silverson mixer, capacities typically range from laboratory scale (1-5 litres) up to pilot or small production volumes (50-200 litres), depending on the specific head configuration and motor power.

Power supply

This unit is specified as single phase. Silverson mixers commonly operate on standard industrial single-phase (e.g., 230V, 50Hz in the UK) or three-phase power supplies, with motor sizes typically ranging from 0.37 kW to 11 kW for this type of mixer.

Construction material

As described, the unit is all stainless steel construction, which is standard for high-shear mixers used in hygienic applications to ensure corrosion resistance and ease of cleaning.

Shear type

Silverson mixers are high-shear rotor/stator devices, designed to rapidly mix, emulsify, homogenise, disintegrate, and dissolve materials.

Mounting

This unit includes a stand, indicating it is a floor-standing or bench-mounted model, common for versatile use across different vessels.

Speed control

Many Silverson mixers, especially modern or refurbished units, feature variable speed control via an inverter, allowing for process optimisation across different product viscosities and shear requirements.

• What is the primary benefit of a high-shear mixer over a conventional stirrer?

  High-shear mixers provide significantly more intensive mixing, capable of creating fine emulsions, stable suspensions, and rapidly dissolving solids, which conventional stirrers cannot achieve effectively.

• Can this mixer handle abrasive products?

• What maintenance is typically required for a Silverson mixer?

• Is this mixer suitable for ATEX environments?

• What types of products are best suited for a Silverson mixer?

Lab mixers and stirrers hold strong reputations for reliability and durability. Buyers typically prioritise motor condition, speed range suitability, and vessel compatibility when purchasing used units. The equipment category is valued for consistent performance across research and production settings. Key strengths include robust construction, straightforward maintenance, and long operational lifespans. Corrosion resistance of wetted parts merits careful inspection. These devices remain dependable workhorses in pharmaceutical, biotech, and laboratory environments, offering solid value when sourced from reputable sellers with clear service histories.
