Product Description
LIGHT LABS is proud to offer the Benchmark Scientific BenchRocker™ 2D Variable Speed Platform Rocker (Cat # BR2000) — the versatile, full-featured variable-speed platform rocker that expands upon the fixed-speed BenchBlotter™ BR1000 with independent adjustment of both rocking speed (2–30 RPM) and tilt angle (0°–30°) for precise optimization across the widest possible range of molecular biology, cell biology, biochemistry, and general laboratory rocking applications. The BenchRocker™ 2D is the ideal rocker for laboratories requiring the flexibility to tailor rocking conditions to specific vessel sizes, liquid volumes, and application requirements — from ultra-gentle low-speed, low-angle rocking for non-foaming blot washing and delicate membrane incubations through vigorous high-speed, high-angle agitation for rapid sample mixing and extraction.
The dual adjustability of the BR2000 is its defining advantage over the fixed-speed BR1000 BenchBlotter™. At low speeds (2–5 RPM) and minimal tilt angles (0°–5°), the BenchRocker™ 2D produces a gentle wave effect across the platform surface — the non-foaming, even coverage motion required for blot washing, gel staining/destaining, antibody incubations, and hybridization. At higher speeds (15–30 RPM) and more extreme tilt angles (15°–30°), it produces aggressive agitation for vigorous sample resuspension, extraction, and mixing applications. The ability to precisely dial in both parameters — matching speed and tilt to the specific vessel size and liquid volume being rocked — delivers optimum mixing performance for any application and any container format on the same instrument.
The BR2000 features a maintenance-free brushless DC motor — a significant engineering advantage that eliminates the most common failure point of conventional rocker motors (brush wear), providing longer service life, quieter operation, and reduced maintenance requirements vs. brushed motor rockers. The large 14" x 12" (35 x 30 cm) platform accommodates multiple gel boxes, blot containers, staining trays, and other vessels simultaneously. An optional stacking platform accessory (BR2000-STACK) doubles the available working area without increasing bench footprint. Cold room and incubator compatible (+4°C to +45°C). 2-year warranty. LIGHT LABS is your trusted source for Benchmark Scientific laboratory equipment.
KEY FEATURES
- Variable speed: 2–30 RPM — from ultra-gentle wave-effect rocking (2 RPM) through vigorous agitation (30 RPM); precise speed dial control
- Variable tilt angle: 0°–30° — from nearly flat gentle wave through aggressive 30° see-saw rocking; independent tilt adjustment
- Dual parameter optimization — adjust speed AND tilt independently to precisely match rocking conditions to vessel size, liquid volume, and application requirements
- Maintenance-free brushless DC motor — eliminates brush wear failure; longer service life, quieter operation, and reduced maintenance vs. brushed motors
