Heavy-Duty Multi-Sample Mixing for Demanding Laboratories

The Ohaus VXHDAL heavy-duty analog multi vortex mixer is engineered for laboratories that routinely mix large numbers of samples or heavier vessels and need reliable continuous-duty performance.

Driven by a high-quality German motor, the VXHDAL operates across its entire speed range without overheating, even when fully loaded with accessories weighing up to 1.1 kg. This makes it ideal for microtube racks, microplates and flask holders used in pharmaceutical, biotechnology and QC environments.

With a 4.9 mm orbital motion, the mixer generates intense turbulence inside tubes and flasks, significantly reducing mixing times for viscous or particulate samples.

Analog control allows operators to fine-tune speed using a rotary dial — from gentle resuspension to aggressive vortexing — while touch-mode and continuous-run modes support both single-tube and batch workflows.

Built for Stability, Safety and Accessory Flexibility

A heavy, vibration-damping base keeps the instrument stable even at maximum load. The chemical-resistant housing withstands routine laboratory cleaning and spills.

As standard, the VXHDAL is supplied with:

• Universal holder

• Cup head

• Foam insert for microtubes

• Universal cover

A broad range of optional tube racks, microplate holders and flask clamps is available, making this model exceptionally versatile for high-throughput laboratories.

Typical Applications

• High-throughput sample preparation

• Microplate mixing

• Cell pellet resuspension

• Dissolution of viscous reagents

• Pharmaceutical QC and research labs
