Homogenizers & Sonicators

The choice depends on how tough the material is and what you want to recover intact. Soft tissue and cell suspensions suit rotor stator shear or ultrasonic probes, while tough tissue, seeds and spores need bead beating. If you must preserve large fragile molecules, gentler methods reduce damage. Describe your sample to the seller so they can confirm the listed instrument matches.

Disruption puts energy into the sample as heat, which can damage enzymes and other labile targets. Cooling the sample on ice, pulsing the energy and limiting run time all help control the temperature. Some instruments offer jacketed vessels or programmed pulse cycles. Ask the seller whether the unit supports pulsing and cooling so your targets stay intact.

The probe tip wears with use and cavitation, so ask about its condition and whether spares are available. Check that the generator delivers its rated power and that the horn couples properly to the probe. A worn or pitted tip reduces energy transfer and can contaminate samples. A recent function check and a sound probe make for a reliable purchase.

Each instrument works best over a defined volume range, and probes or vessels often need changing to cover very small or large samples. Check the minimum and maximum volumes the unit handles and which probes or tubes it accepts. If your volumes vary widely, confirm the right accessories are included. The seller can advise whether the listed unit covers your range.

Contact the seller directly and ask for photos of the probe and generator, a service history and a video of the unit running. With nobody in between, setting up an inspection or demonstration is easy. Sellers on the marketplace are verified, which adds confidence. Agree any test you want before completing the purchase.
