Clinical centrifuge Sorvall ST1R Plus

for general purposesfor researchfor sample preparation

Short description
Refrigerated general‑purpose centrifuge with a 1.6 L maximum capacity, tool‑less Auto‑Lock rotor exchange and SMARTSpin imbalance management. Designed for routine blood and tube processing with up to 76 x 5/7 mL or 16 x 50 mL capacity.

Product overview
The Sorvall ST1R Plus series features a high‑contrast LCD, intuitive keypad and motorized lid latch for one‑handed closing. The unit supports 14 rotor options with rapid, tool‑free swaps and includes biocontainment bucket sealing. Refrigeration and SMARTSpin control deliver repeatable separations for clinical and research workflows.

Easy to use

• Clear controls and display store up to 6 programs for repeatable protocols and simplified operation.
• Ergonomic rotor loading and a low‑profile drive reduce operator strain and improve bench workflow.
• Motorized lid latch enables a single downward motion to close and lock the lid, facilitating use on tall benches.

Thermo Scientific™ Auto‑Lock™ III Rotor System

• Push‑button rotor installation secures rotors quickly without tools for fast application changes.
• Reduces downtime when switching between rotors and protocols.
• Accessible rotor chamber simplifies cleaning and maintenance.

Thermo Scientific™ ClickSeal™ Bucket Sealing System

• Snap‑fit bucket seals eliminate screw caps and complex clips for reliable biocontainment.
• Glove‑friendly, one‑hand open/close action improves lab ergonomics.
• Certified by CAMR™ (Porton Down, UK) for containment performance.

Thermo Scientific™ SMARTSpin™ Technology

• Advanced rotor management optimizes acceleration, braking and residual imbalance per rotor/bucket combination.
• Enhances safety while improving separation performance and reproducibility.

Space‑saving design

• Compact footprint and ergonomic height support efficient bench integration, easy sample loading/unloading and straightforward cleaning.

Energy efficient

• Up to 40% energy savings on standard protocols (e.g., blood separation, conical tube processing) compared with industry averages.
