The B3D1320 is the standard-size BioMixer 3D Nutating Shaker — same dimpled-mat design as the MiniMixer (B3D1020) at the larger 12"×12" platform for multi-tube simultaneous mixing and higher-throughput tube workflows. Sold at $602 ($118 step over the MiniMixer at $484). At the standard platform tier, the Rocker and Nutating Shaker variants are same-priced ($602 = same as B3D1308 BlotBoy) — vs the Mini tier where the MiniMixer is $13 cheaper than the Mini BlotBoy.

Why the 12"×12" Standard Platform — Multi-Tube Throughput
The standard 12"×12" dimpled mat supports substantially more tubes than the Mini's 10"×7.5" — multi-investigator tube-mixing with several investigators' tubes at once, higher-throughput cell-staining and suspension-culture batches, parallel multi-batch sample-prep mixing, and multi-investigator antibody-staining IHC workflows in tube format.
Pick the BioMixer (B3D1320) when:
- Workflow processes multi-tube simultaneous mixing at facility-scale throughput
- Multi-investigator shared shaker procurement at moderate-large throughput
- Cell-staining facility procurement — TC-room workflows where multi-tube mixing is the standard cycle
- The MiniMixer has been throughput-limiting (single-batch tube workflow becoming a bottleneck)
Stay with B3D1020 MiniMixer ($484) when small-batch single-investigator tube workflows are the routine — $118 saving when the larger platform is excess capacity.
Platform Size Comparison — Nutating Shaker Family
| SKU | Platform | Best for | List price |
| B3D1020 MiniMixer | 10" × 7.5" | Single-investigator tube mixing / small-batch | $484 |

B3D Family Pricing Pattern Note
At the standard platform size, the BlotBoy Rocker and BioMixer Nutating Shaker are same-priced at $602. At the Mini platform size, the Rocker (Mini BlotBoy, $497) is $13 more than the Nutating Shaker (MiniMixer, $484). Pricing converges at the larger platform tier.

Frequently Asked Questions
Q: How does the BioMixer differ from the MiniMixer? A: Same 3D nutating dimpled-mat design at a larger 12"×12" platform (vs 10"×7.5") for multi-tube throughput, at $602 vs $484.
Q: What's the difference between the BioMixer and the BlotBoy at this size? A: The BioMixer (B3D1320) uses a dimpled mat for tubes; the BlotBoy (B3D1308) uses a flat mat for membranes/trays — both $602 at the 12"×12" platform.
Q: What motion does it use? A: 3D nutating motion (orbital + tilt combined), with a dimpled mat that holds tubes during motion.
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
Confirm tube-format compatibility — confirm specific tube formats fit the standard-platform dimpled mat dimensions; tube counts at the 12"×12" platform are substantially higher than Mini.
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-tube workflow context, bench-space confirmation, tube-format compatibility, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms — confirm at quote.
