Floor-Stand High-Speed Homogenizer for Large Volumes

What is the Floor-Stand High-Speed Homogenizer for Large Volumes?

A floor-stand high-speed homogenizer uses a heavy motor on a column with motorized lift to process 5 to 200 L in drums and vessels. It serves pilot-scale emulsification and dispersion where benchtop motors are insufficient.

Overview

The floor-stand homogenizer carries a 1.5 to 15 kW motor on a column with a motorized or hydraulic lift and swing arm. A long shaft, up to 1 m, carries a large rotor-stator head of 60 to 150 mm diameter. Speed is typically 500 to 10,000 rpm, controlled by a frequency converter, with tip speeds of 10 to 35 m/s. The head can be positioned in drums or vessels from 5 to 200 L, and the arm allows the unit to be moved aside for emptying. A safety guard, emergency stop and overload protection are fitted. Stainless steel shafts and shaft seals suit food, pharmaceutical and chemical materials. Noise is higher, 75 to 90 dB(A), so a sound enclosure may be needed. The design fills the gap between laboratory and production scale, enabling pilot batches to be made with the same generator geometry as production.

How does it work?

A high-speed homogenizer drives a rotor inside a fixed stator at speeds of roughly 5,000 to 30,000 rpm. The rotation creates suction that draws sample into the probe from below, then centrifugal force pushes it radially through slots in the stator. The narrow gap, often 0.15 to 0.5 mm, produces intense mechanical shear, turbulence and, at high speed, cavitation. These forces break tissue fragments, disperse solids and reduce droplets to a few micrometers. Energy transfers as heat, so cooling is often needed for biological samples. Main components are the motor, a drive shaft with dispersing tool, interchangeable rotor-stator generators, a speed controller and a support stand or handle. Probe diameter, slot design and speed determine the working volume, typically from 0.1 mL to 20 L, and the final particle size.

What are the key features?

• Heavy 1.5–15 kW motor on a floor column with motorized lift
• Shaft up to about 1 m to reach deep drums and vessels
• Frequency-controlled speed of 500–10,000 rpm
• Swing arm moves the head aside for vessel changes
• Safety guard, emergency stop and overload protection
• Stainless steel shaft and seals suited to food and pharmaceutical use

What are the technical specifications?

A typical floor-stand high-speed homogenizer for large volumes configuration offers working volume of 5–200 L, speed range of 500–10,000 rpm, tip speed of 10–35 m/s, motor power of 1.5–15 kW, head diameter of 60–150 mm and shaft length of Up to about 1 m. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Floor-Stand High-Speed Homogenizer for Large Volumes is used in pilot-scale emulsification, large-volume dispersion, food and sauce batches, chemical slurry homogenization and cosmetic bulk production trials. Across the wider High-Speed Homogenizers class, laboratories also deploy it for tissue disruption for DNA, RNA and protein extraction, emulsion and cream preparation and pharmaceutical suspension dispersion.

Which standards and certifications apply?

Relevant standards and methods include IEC 61010-1, IEC 61010-2-051, ISO 13320, EN ISO 12100 and GB 4793.1. Certification candidates for this model are CE, RoHS and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Keep the probe immersed to at least the minimum depth during operation to avoid air entrainment, splashing and seal damage. Clamp vessels securely, and use ice baths or short bursts to prevent heating of biological samples. Wear eye protection and guards, and always keep the probe stationary when lifting it from the sample. Clean the probe immediately after use by running it in water and then in detergent or solvent suitable for your sample. Inspect generators for wear, because damaged stators give inconsistent results. Follow IEC 61010-1 for electrical safety. For biological and infectious materials, use a biosafety cabinet or closed system and decontaminate the probe according to your biosafety procedures. Record speed, time and temperature to support reproducibility.

How do I select the right Floor-Stand High-Speed Homogenizer for Large Volumes?

Select a floor-stand unit for pilot batches of 5 to 200 L where a benchtop motor would overheat or lack torque. For volumes below 20 L a benchtop model is sufficient. In the RFQ, specify vessel size, viscosity, motor power, shaft length, sound and explosion-protection needs.

How does it compare with other High-Speed Homogenizers variants?

Choose a high-speed homogenizer by working volume, sample type, speed range and format. Handheld units are portable and suited to small volumes in tubes and beakers. Benchtop digital units provide precise speed, timer and torque feedback for reproducible protocols. Micro-volume models work with 0.1 to 10 mL samples in microtubes. Large floor-stand units process liters to tens of liters in pilot work. Disposable-probe systems prevent cross-contamination in clinical and molecular workflows. Consider the maximum speed and the generator options, and whether the probe materials such as 316L stainless steel or PTFE are compatible with your samples. Verify noise, vibration and safety features. Ask the supplier about tip speed, particle size results and cleaning procedures, and request a demonstration with your own sample where possible.
