The B3D-STACK-D is the dimpled-mat sister of the B3D-STACK stacking platform — sold at $160 ($6 premium over the flat-mat sister at $154). Same 3.0" tier-clearance stacking design, different mat — the dimpled mat holds tubes in place during dual-tier nutating motion, supporting tube-format throughput doubling on Mini-platform B3D chassis.
For full chemistry rationale (stacking platform vertical-throughput economics, bench-space-efficient capacity scaling), see the B3D-STACK (flat-mat sister) parent page.
| SKU | B3D-STACK-D |
| Type | Stacking platform with dimpled mat for Mini-platform B3D chassis |
| Tier clearance | 3.0" between primary platform and stacking platform |
| Stacking-platform mat | Dimpled mat (holds tubes during nutating motion) |
| Compatible chassis | B3D1020 (MiniMixer), B3D1008 (Mini BlotBoy converted to tube workflow) |
| Sister stacking platform SKU | B3D-STACK (flat-mat version, $154) |
| Sister large-platform stacking SKU | B3D5000-STK (BenchWaver flat-mat stacking, $169) |
| List price | $160 |
Pick the B3D-STACK-D when:
Pick the flat-mat sister (B3D-STACK, $154) for tray / membrane workflows — different mat type for different workflow.
| SKU | Mat type | Tier clearance | List price |
| B3D-STACK | Flat | 3.0" | $154 |
| B3D-STACK-D (this product) | Dimpled | 3.0" | $160 |
| B3D5000-STK | Flat (BenchWaver) | 4.5" | $169 |
Pair with B3D1008 / B3D1020 Mini chassis. Confirm chassis inventory at order.
Confirm tube formats fit the 3.0" clearance — tubes on the lower tier must fit beneath the stacking platform clearance. Standard 1.5/2.0 mL Eppendorf tubes (~3.7 cm tall) and 15 mL conical tubes (~12 cm tall) — confirm specific tube height fit at order.
Pair with replacement mat (B3D-DIMPLED, $45) for ongoing dimpled-mat replacement on the stacking platform.
Confirm at quote: chassis pairing, tube-format height fit, intended dual-tier workflow context, and lead time.
Warranty: Per Benchmark Scientific standard accessory terms.
B3D Mini stacking platform family:
- B3D-STACK — Mini stacking with flat mat ($154) — for membrane / tray workflows
- B3D-STACK-D (this product) — Mini stacking with dimpled mat ($160) — for tube workflows
Pick the dimpled-mat stacking for dual-tier tube-mixing workflows; see B3D-STACK anchor for full stacking-platform rationale.
