The BR2000-STACK is the stacking platform for the BR2000 BenchRocker 2D Variable Speed Rocker, sold at $168. The stacking platform creates a second tier 3.0" above the BR2000 primary platform, allowing two layers of trays / membranes simultaneously in a single rocker cycle on the extra-large 14"×12" platform. Effectively doubles per-cycle throughput at the BR2000's largest 2D platform scale. Pair with BR2000-SP separators ($60) to extend clearance to 4.25" for taller items on the lower tier.
| SKU | BR2000-STACK |
| Type | Stacking platform with flat mat for BR2000 chassis |
| Tier clearance | 3.0" base clearance (extendable to 4.25" with BR2000-SP separators) |
| Stacking-platform mat | Flat mat (sized 14" × 12") |
| Compatible chassis | BR2000 (BenchRocker 2D Variable Speed) ONLY |
| Compatible separator accessory | BR2000-SP (additional separators, +1.25" clearance, $60) |
| Sister stacking platforms (different chasses) | BR1000-STACK (12"×12" for BR1000, $154), B3D-STACK (small for Mini B3D, $154), B3D5000-STK (largest for BenchWaver, $169) |
| List price | $168 |
| Configuration | Per-cycle throughput | Cost |
| BR2000 chassis alone | Single tier (14" × 12" workflow surface) | $915 |
| BR2000 + stacking platform (this product) | Dual tier (2 × 14" × 12" workflow surfaces) | $915 + $168 = $1,083 |
| BR2000 + stacking + separators | Dual tier (4.25" lower clearance) | $915 + $168 + $60 = $1,143 |
| Two BR2000 chasses | Dual single-tier (parallel) | $1,830 |
The stacking platform delivers 100% throughput doubling at ~18% additional procurement cost: meaningful ROI vs duplicate-chassis procurement.
Pick the BR2000-STACK when:
Pair with BR2000-SP if lower-tier items exceed 3.0" height (extends clearance to 4.25").
| SKU | Platform | Base clearance | List price |
| B3D-STACK / -STACK-D | Small (10.5"×7.5") | 3.0" | $154 / $160 |
| BR1000-STACK / -STACK-D | Large (12"×12") | 3.0" | $154 / $160 |
| BR2000-STACK (this product) | Extra-large (14"×12") | 3.0" (extendable to 4.25") | $168 |
| B3D5000-STK | Largest (13.5"×13") | 4.5" | $169 |
Pair with BR2000 chassis. Confirm BR2000 chassis inventory at order.
Pair with BR2000-SP separators if lower-tier items need >3.0" clearance.
Confirm tray / membrane height fit. Items on the lower tier must fit beneath the stacking-platform clearance (3.0" base or 4.25" with separators). Confirm tray heights at order.
Confirm dimpled-mat availability. Universe doesn't show a BR2000-STACK-D dimpled-mat sister. Confirm with Benchmark Scientific tech support if dual-tier tube workflows on BR2000 chassis are intended.
Confirm at quote: chassis pairing (specifically BR2000), tray height fit, separator pairing if needed, dimpled-mat availability if needed, and lead time.
Warranty: Per Benchmark Scientific standard accessory terms.
BR2000 stacking accessory family:
- BR2000-STACK (this product): Stacking platform with flat mat ($168), dual-tier throughput doubling
- BR2000-SP: Additional separators, +1.25" clearance ($60)
Pick the BR2000-STACK for dual-tier 14×12" workflow throughput; pair with separators for taller-item clearance. Sister BR1000-STACK ($154) covers the smaller 12×12" BR1000 chassis (different dimensions).
