The Ohaus VXMTALB multi-tube analog vortex mixer is built for hands-free, high-throughput mixing of multiple tubes at once.

Featuring analog speed control and a 1200–2400 rpm range, it handles anything from gentle resuspension to aggressive vortexing.

Its 3.6 mm orbit ensures efficient agitation across racks of samples.

With a 4.5 kg load capacity and continuous-duty rating, the VXMTALB is ideal for busy pharmaceutical, diagnostic and research laboratories.

Supplied with a standard foam rack for 50 × 12 mm tubes and suction-cup feet for excellent bench stability.

High-Throughput Multi-Tube Mixing for Busy Laboratories

The Ohaus VXMTALB multi-tube analog vortex mixer is engineered for laboratories that process dozens of tubes simultaneously and need dependable continuous-run performance.

With a variable analog speed range of 1200–2400 rpm and a 3.6 mm orbital motion, the instrument produces vigorous, uniform mixing across full foam racks — dramatically improving productivity compared to single-tube vortexers.

Rated for continuous duty and supporting loads up to 4.5 kg, the VXMTALB easily handles dense racks of microtubes or culture tubes without overheating.

Painted Steel Housing for Cost-Effective Performance

This VXMTALB version features a two-piece painted steel housing, offering an economical alternative to stainless steel models while maintaining mechanical robustness.

Strong suction-cup feet reduce vibration and prevent sliding during operation, even at maximum load.

Flexible Tube Rack System

As standard, the VXMTALB is delivered with:

Foam rack for 50 × 12 mm tubes
Detachable power cord
Tray pad set

Interchangeable foam racks are available for tube diameters from 10 to 29 mm, as well as 50 mL tube racks and post-extension kits for taller vessels — making this multi-vortexer adaptable to a wide range of workflows.

Typical Applications

High-throughput QC sample preparation
Diagnostic laboratory batch processing
Microbiology tube mixing
Pharmaceutical research
Biotech screening labs
