Product Description
LIGHT LABS is proud to offer the Benchmark Scientific Orbi-Shaker™ XL (Cat # BT1011) — the highest-capacity, most powerful orbital shaker in the Benchmark Scientific benchtop lineup, delivering flask capacity that far exceeds most benchtop orbital shaker models. With a massive 18" x 18" (45 x 45 cm) platform and a powerful beltless motor drive, the Orbi-Shaker™ XL is capable of simultaneously shaking up to five 2L Erlenmeyer flasks or nine 1L flasks — making it the go-to orbital shaker for microbiology, molecular biology, biochemistry, and protein expression labs running large-scale or high-throughput liquid culture workflows that require maximum simultaneous flask capacity in a benchtop instrument.
The beltless motor drive is a critical engineering distinction that separates the Orbi-Shaker™ XL from most competing high-capacity orbital shakers. Conventional orbital shakers use a drive belt to transfer motor rotation to the shaking platform — belts are subject to wear, stretching, and breakage, particularly at high loads and extended run times. The Orbi-Shaker™ XL eliminates the belt entirely through a direct-drive beltless motor system — providing more reliable, more consistent, and more maintenance-free shaking performance at the highest platform loads, with no belt to replace or tension to adjust. The result is consistent 19mm circular orbital motion at any speed from 30 to 300 RPM across the full 65 lb load capacity, regardless of how many flasks are mounted.
The touch screen control panel provides precise 1 RPM speed increment control — the finest speed resolution of any Benchmark Scientific orbital shaker — along with a programmable timer (1 min to 99 hours or continuous) for fully automated unattended shaking protocols. The included non-slip rubber mat platform is ideal for low-speed applications; the optional MAGic Clamp™ platform (sold separately) enables high-speed mixing of Erlenmeyer flasks with instant tool-free magnetic clamp exchange. Cold room and incubator compatible (+4°C to +65°C). 2-year warranty. LIGHT LABS is your trusted source for Benchmark Scientific laboratory equipment.
KEY FEATURES
- Highest flask capacity of any Benchmark Scientific benchtop orbital shaker — up to 5 x 2L or 9 x 1L Erlenmeyer flasks simultaneously on the 18" x 18" platform
- Beltless motor drive — eliminates belt wear, stretching, and breakage; more reliable, consistent, and maintenance-free than belt-driven shakers at maximum load
- Massive 18" x 18" (45 x 45 cm) platform — largest platform in the Benchmark Scientific orbital shaker lineup; 4x the area of the Orbi-Shaker™ Jr BT302
- Touch screen control panel — intuitive digital control with 1 RPM speed increment resolution; finest speed control in the lineup
- Variable speed: 30–300 RPM in 1 RPM increments — precise speed optimization for any culture or shaking application
- 19mm horizontal circular orbit — same proven orbit as the Orbi-Shaker™ Jr; provides thorough mixing AND aeration simultaneously
- Programmable timer: 1 min to 99 hr or continuous — fully automated unattended shaking
- 65 lb (30 kg) maximum load capacity — highest load capacity of any Benchmark Scientific orbital shaker
- Patented MAGic Clamp™ compatible — optional MAGic Clamp platform enables instant tool-free magnetic flask clamp exchange for high-speed applications
- Included non-slip rubber mat — ideal for low-speed gel staining, tissue culture flask, and petri dish applications
- Low-profile design: 5" height — fits under standard laboratory shelving
- Cold room and incubator compatible — +4°C to +65°C
- 120V or 230V, 50–60 Hz
- Dimensions: 18.5" x 21.25" x 5" (47 x 54 x 12.5 cm)
- Weight: 65 lbs (30 kg)
