If you’ve spent any time in a lab, you know the value of equipment you can truly rely on. The Ratek VM1 Vortex Mixer has been that reliable sidekick for scientists, technicians, and students for over 30 years — and it’s still going strong.
This single-tube vortex mixer isn’t just about mixing liquids; it’s about making your work faster, easier, and more consistent. Whether you’re swirling cells in microbiology, blending reagents in analytical chemistry, or just trying to get that stubborn precipitate to dissolve, the VM1 handles it all.
Gentle Swirl or Full Vortex — You Decide
With a speed range from 200–2700 RPM, the VM1 gives you complete control. Need a light mix for a delicate sample? Easy. Want to create a full-blown tornado in your test tube? It’s got you covered. You can even fine-tune the action by changing the angle and pressure of the tube in the cup.
Two Modes, One Reliable Mixer
The VM1 is built for real-world lab workflows:
-
Manual Mode – Works only when you press down on the silicon cup. Perfect for quick, one-off jobs.
-
Automatic Mode – Runs continuously, so you can focus on other tasks while it mixes.
Built Like a Tank (But Runs Like Silk)
Under the hood, the VM1’s counterbalanced drive system keeps things smooth and quiet, even at top speeds. And when we say it’s built to last, we mean it — there are labs out there still using VM1 units that were purchased over 20 years ago. That’s some serious engineering.
Why Australian Labs Love the VM1
This mixer is ideal for test tubes up to 28 mm in diameter and is used in research, teaching, and industrial labs all over Australia. It’s a dependable all-rounder for suspending cells, mixing assay reagents, or combining solutions before analysis.
The bottom line? If you want a vortex mixer that’s easy to use, endlessly reliable, and proudly made for Australian labs, the Ratek VM1 is a smart choice — and likely the last mixer you’ll need to buy for a long time.
