The BR5404 is the QuadRocker — a premium 4-tier rocker with built-in multi-platform design in the Benchmark Scientific BR family, sold at $1,825. Distinct from the BR1000 / BR2000 / BR5000 single-platform sisters, the QuadRocker delivers 4 simultaneous platforms in one chassis — 4× per-cycle throughput vs single-platform rockers, in a factory-integrated multi-tier design (vs add-on stacking platforms which double throughput at most).

Why a Built-In 4-Tier Multi-Platform — Production-Scale Throughput
Single-platform rockers process one layer of trays / membranes per cycle. Add-on stacking platforms (BR1000-STACK, BR2000-STACK, BR5000-STACK, B3D5000-STK) double throughput to 2 platforms per cycle at the cost of an accessory. The QuadRocker quadruples throughput to 4 platforms per cycle in factory-integrated design:
| Configuration | Per-cycle throughput | Total cost |
| BR2000 single-platform | 1 platform | $915 |
| BR2000 + stacking | 2 platforms | $1,083 |
| BR5000 + stacking | 2 platforms | $1,533 |
| BR5404 QuadRocker (this product) | 4 platforms | $1,825 |
| 2× BR5000 + stacking each (parallel) | 4 platforms | $3,066 |
| 4× BR1000 chassis (parallel) | 4 platforms | $2,344 |
The QuadRocker delivers 4-platform throughput at meaningful cost savings vs procuring multiple single-platform chasses with stacking — and consolidates the workflow onto a single bench instrument (vs multiple chasses' bench footprint).
Pick the QuadRocker (BR5404) when:
- Workflow processes production-scale multi-membrane / multi-tray workflows at 4× single-platform throughput
- Multi-investigator shared facility procurement — 4-tier built-in supports 4 simultaneous investigators per cycle
- Pharmaceutical / biotech research at production scale — high-throughput multi-membrane workflows
- Bench-space-constrained facilities — single instrument vs 4 separate chasses
- Cost-efficient production-scale procurement — meaningful savings vs multi-chassis or chassis+stacking duplicate-procurement
Stay with single-platform rockers (BR1000 / BR2000 / BR5000) when single-platform throughput matches workflow needs and the QuadRocker is excess capacity.

Frequently Asked Questions
Q: How many platforms does the QuadRocker have? A: Four built-in platforms in one chassis, delivering 4× the per-cycle throughput of a single-platform rocker.
Q: How does the BR5404 compare to add-on stacking platforms? A: Stacking platforms double throughput to 2 platforms per cycle; the QuadRocker is a factory-integrated 4-platform design, at meaningful cost savings versus running multiple chasses with stacking.
Q: Is the speed adjustable? A: Yes — the QuadRocker uses variable speed control with 2D single-axis tilt rocking motion.
Q: What voltage does it use? A: 115 V or 230 V, 50–60 Hz (discrete variants). A 230 V EU-plug configuration is available by special order at the same $1,825.
Ordering & Configuration
Confirm per-platform dimensions and inter-platform clearance. The QuadRocker design implies tight platform-to-platform clearance — confirm dimensions with Benchmark Scientific tech support to verify workflow item-height compatibility.
Confirm load capacity per platform. Multi-platform designs distribute load across the chassis — confirm per-platform load specs at facility-scale workflow planning.
Confirm voltage and plug type. 115 V / 230 V chassis; a 230 V EU-plug configuration is available by special order at the same $1,825.
Confirm bench-space. The 4-tier built-in design has substantial vertical / horizontal envelope — confirm available facility space at order.
Confirm at quote: voltage and plug type, intended 4-platform workflow context, per-platform dimensions / clearance / load fit, bench-space, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms — confirm at quote.
BR family — pick the right tier:
- BR1000 — Fixed-speed BenchBlotter, single platform ($586)
- BR2000 — Variable-speed BenchRocker 2D, single platform ($915)
- BR5000 — Everlast variable-speed, single platform ($1,825.00) — premium heavy-duty
- BR5404 (this product) — QuadRocker 4-tier variable-speed ($1,825) — built-in 4× throughput
Pick the QuadRocker for production-scale 4× throughput in a single chassis; sister single-platform sisters cover lower-throughput workflows; cross-family B3D / BR add-on stacking platforms cover 2× throughput on single-platform chasses.
