Globe Scientific Tube Roller-Mixer, 36 RPM, 11° Rocking Angle, 240V/50Hz — 1/Each
The Globe Scientific Tube Roller-Mixer combines continuous rolling with an 11° rocking motion for thorough, low-shear blending of blood, viscous reagents, and cell suspensions. Operating at a fixed 36 RPM on 240V/50Hz, it keeps samples homogenized without foaming — ideal for hematology, blood banking, and reagent preparation. Sold individually per unit.

Frequently Asked Questions
What is the difference between the two SKUs?
Both units are identical in performance — 36 RPM, 11° rocking angle, 240V/50Hz. GTRM-FS-EU carries an EU plug and GTRM-FS-UK carries a UK plug. Choose based on your facility's outlet standard.
Will this operate on US 120V power?
No. Both versions are rated for 240V, 50Hz only. North American labs running 120V/60Hz should verify outlet compatibility or use an appropriate voltage transformer before deployment.
How does the rocking angle improve mixing?
Pairing 36 RPM rolling with an 11° rocking tilt creates a three-dimensional flow inside each tube. This prevents settling and produces uniform suspensions while minimizing foaming and shear stress on cells.
What tube sizes does the roller accommodate?
The roller platform handles standard round-bottom blood collection and laboratory tubes across common diameters. Position tubes evenly across the rollers for balanced, consistent mixing.
