Globe Scientific Tube Roller (GTR-AVS) Overview
The Globe Scientific Analog Variable Speed Tube Roller (GTR-AVS) delivers gentle, continuous rolling action across six rollers, supporting consistent sample homogenization for tubes of varying sizes. Designed for routine bench work, this unit pairs analog control with a multi-voltage power range that adapts to laboratories worldwide.
Variable speed adjustment lets technicians tune agitation intensity to match delicate or robust samples. Six rollers handle multiple tubes simultaneously, improving throughput during blood specimen mixing, reagent suspension, and similar protocols. The analog dial keeps operation simple and intuitive for shared lab settings.
Rated for 120-240v at 50/60Hz, the GTR-AVS ships with US, UK, and EU plugs, so facilities can deploy it without sourcing regional adapters. Globe Scientific builds this roller for everyday laboratory reliability.

Laboratory Applications
Tube rollers keep blood and other suspended specimens evenly mixed prior to analysis, preventing settling that can skew results. Hematology and clinical labs rely on continuous rolling to maintain cell suspension in collection tubes before testing or aliquoting.
Beyond clinical use, rollers support gentle mixing of reagents, viscous solutions, and sensitive biological samples where vortexing would be too aggressive. Research and quality-control teams use roller mixers to maintain homogeneity over extended incubation or staging periods.

Frequently Asked Questions
How many tubes can the GTR-AVS hold?
This unit features six rollers, allowing multiple tubes to be mixed at once across the roller bed. Exact tube capacity depends on tube diameter and length; contact us for guidance on your specific tube format.
Will this roller work outside the United States?
Yes. Rated for 120-240v at 50/60Hz and supplied with US, UK, and EU plugs, the GTR-AVS is ready for deployment across most regional power standards without additional adapters.
Can I adjust the rolling speed?
The GTR-AVS uses analog variable speed control, letting technicians set agitation intensity by dial. Specific speed range values are not listed; contact us for detailed performance specifications.
