Product Description
LIGHT LABS is proud to offer the Benchmark Scientific QuadRocker™ (Cat # BR5404) — a completely unique and transformative concept in laboratory platform rocking, featuring a patented tiered attachment system that simultaneously rocks up to four 16" x 12" non-slip rubber mat platforms — providing a total combined work surface of over 750 square inches in a single instrument footprint. The QuadRocker™ is the definitive solution for high-throughput molecular biology laboratories, core facilities, and research groups that regularly run large numbers of simultaneous gel blotting, washing, staining, or incubation steps — where conventional single-platform rockers create a critical bottleneck requiring multiple instruments, staggered processing, or extended protocol times.
The four-platform tiered design of the BR5404 is the breakthrough that makes the QuadRocker™ unique in the laboratory equipment market. While all other platform rockers — including the BR5000 with its optional stacking platform — provide at most two rocking levels, the QuadRocker™ provides four rocking levels simultaneously on a single motor and drive system, multiplying productive rocking capacity by 4x without any additional bench space beyond the single instrument footprint. The base level plus three additional stacking platforms together provide over 750 square inches of rocking work surface — enough to run four full-size gel blotting or staining experiments simultaneously.
The QuadRocker™'s platform configuration is fully user-adjustable — for standard gel blotting, washing, and staining applications, all four platforms are installed at standard spacing. For applications requiring taller vessels (deep blotting boxes, large containers, roller bottles), the platforms can be repositioned to provide up to 8¼ inches (21 cm) of clearance between levels — accommodating virtually any vessel format. Digital speed and timer controls — a step up from the analog controls of the BR5000 — provide precise, reproducible rocking conditions with a programmable timer for walk-away automated rocking protocols. 2-year warranty. LIGHT LABS is your trusted source for Benchmark Scientific laboratory equipment.
KEY FEATURES
