Lab Shakers - Precision Movements and Repeatability Matter the Most

The breadth of this field reflects the wide range of applications. Shakers mix solutions for chemists, molecular biologists, physical scientists, and others. Many users, though, seek a particular style of shaking. “End users are reaching out for a very specific motion that they require for their applications,” says Nicole Kvasnicka, product marketing manager at Heidolph, headquartered in Schwabach, Germany. “They need to be very specific to not damage their samples.”

A range of specifications describes what a particular shaker does. Typically, a user looks for a shaker that provides a specific speed, often described in revolutions per minute (rpm), and one that carries a certain load, such as a number of flasks. For a shaker that moves items back and forth, the user might care about the stroke length—how far the carrying tray moves from left to right. Some users even want a shaker that goes from stop to stop in a specific amount of time.

Product of Interest

Fused Silica Capillary Columns from QUADREX

Quadrex fused silica columns are produced with the industry standard polyimide outer coating (390°C maximum temperature) for most general GC applications. Columns with high temperature polyimide coatings, for applications >400°C, are available upon request.

Each stationary phase used in our coating processes is synthesized and cleaned in-house to insure column to column reproducibility. All Quadrex phases are bonded to the silica substrate and cross-linked. Our stringent QA / QC program governs the production of all in-house phases which results in accurate selectivity, reproducibility, and outstanding thermal stability.
