The B3D1308 is the standard-size BlotBoy 3D Rocker — same flat-mat design as the Mini BlotBoy (B3D1008) at the larger 12"×12" platform for multi-membrane simultaneous processing and larger-tray workflows. Sold at $602 ($105 step over the Mini BlotBoy at $497).

Why the 12"×12" Standard Platform — Multi-Membrane / Larger-Tray Workflows
The 12"×12" platform is meaningfully larger than the Mini BlotBoy's 10"×7.5" — supporting multiple Western blot membranes simultaneously (vs single-membrane on the Mini), larger Southern/Northern blot membranes at full-gel size, multi-tray immunostaining workflows, larger multi-plate ELISA batches, and multi-investigator shared throughput with several investigators' membranes or trays per cycle.
Pick the BlotBoy (B3D1308) when:
- Workflow processes multi-membrane simultaneous Western blots (high-throughput Western blot workflow)
- Larger-format blot membranes (full-gel Southern / Northern blots)
- Multi-tray immunostaining workflows at facility scale
- The Mini BlotBoy has been throughput-limiting (single-membrane workflow becoming a bottleneck)
Stay with B3D1008 Mini BlotBoy ($497) when single-membrane / small-tray workflows are the routine — $105 saving when the larger platform is excess capacity.

Frequently Asked Questions
Q: How does the B3D1308 differ from the Mini BlotBoy? A: Same flat-mat 3D rocker design at a larger 12"×12" platform (vs 10"×7.5"), at $602 vs $497, for multi-membrane and larger-tray workflows.
Q: How is the BlotBoy different from the BioMixer at this size? A: The BlotBoy (B3D1308) uses a flat mat for membranes/trays; the BioMixer (B3D1320) uses a dimpled mat for tubes — both $602 at the 12"×12" platform.
Q: What motion and speed does it use? A: 3D rocking motion at fixed speed.
Q: Is a 230V version available? A: Yes — 115V/230V chassis; a 230V/50Hz configuration is available by special order at the same $602.
Ordering & Configuration
Pair with appropriate trays / staining containers — see B3D1008 parent for tray / membrane workflow detail.
Confirm voltage and plug type. 115 V / 230 V chassis; a 230 V EU-plug configuration is available by special order at the same $602.
Confirm bench-space. The 12"×12" platform has substantially larger footprint than the Mini's 10"×7.5"; confirm available bench space at order.
Confirm at quote: voltage and plug type, intended multi-membrane workflow context, bench-space confirmation, tray pairing, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms — confirm at quote.
