The B3D1020 is the MiniMixer 3D Nutating Shaker — the Mini-platform, fixed-speed 3D nutating shaker in the Benchmark Scientific B3D family. Sold at $484 ($13 less than the sister Mini BlotBoy Rocker at $497), the MiniMixer delivers 3D nutating motion (combined orbital + tilt motion) on a 10.5"×7.5" platform with dimpled mat — the dimpled mat holds tubes in place during the multi-axis nutating motion. Right pick for tube-content mixing workflows: cell-staining tube mixing, sample-prep tube mixing, tube-format incubation with mixing, and conical-tube content homogenization at modest scale.

Why a Nutating Shaker — Tube-Mixing Workflows
3D nutating motion is distinctively different from rocking motion: rocking motion (BlotBoy family) is smooth multi-axis tilting that sweeps liquid across a flat surface, while nutating motion (MiniMixer / BioMixer family) combines orbital and tilt motion to produce 3D liquid mixing inside tube content.
For tube-content workflows, nutating motion delivers superior internal mixing: it keeps cells in suspension without settling, keeps multi-component reagent mixtures homogeneous, distributes stain uniformly across cell suspensions, and mixes wash buffer uniformly in tube format.
The dimpled mat is the critical accessory feature — the dimples hold tubes in place during the multi-axis nutating motion. A flat mat would let tubes slide / fall during the motion.
Pick the MiniMixer (B3D1020) when:
- Workflow involves tube-format mixing (15 mL conicals, 50 mL conicals, microcentrifuge tubes)
- Cell-staining tube workflows and suspension culture maintenance at modest throughput
- Sample-prep tube mixing for downstream processing
- Bench-space-constrained labs — the Mini platform fits where a larger BioMixer wouldn't
Pick the Mini BlotBoy (B3D1008, $497, $13 premium) for flat-tray / membrane workflows — different mat, different motion type.
Step up to BioMixer (B3D1320, 12"×12", $602) for larger-batch tube mixing at facility scale.

Frequently Asked Questions
What is 3D nutating motion? Combined orbital and tilt motion that produces 3D mixing inside tube contents — different from the flat-surface sweep of rocking motion.
Why does the B3D1020 have a dimpled mat? The dimples hold tubes in place during the multi-axis nutating motion; a flat mat would let tubes slide or fall.
How does the MiniMixer differ from the Mini BlotBoy? The MiniMixer (B3D1020, $484) is a 3D nutating shaker with a dimpled mat for tube-content mixing; the Mini BlotBoy (B3D1008, $497) is a 3D rocker with a flat mat for trays and membranes.
Is the B3D1020 speed adjustable? No — it is a fixed-speed unit.
What platform size and voltage does the B3D1020 use? A 10.5" × 7.5" Mini platform; 115 V or 230 V, 50–60 Hz.
Ordering & Configuration
Confirm tube-format compatibility — confirm specific tube formats (1.5 / 2.0 mL Eppendorf, 15 mL conical, 50 mL conical) fit the dimpled mat dimensions.
Confirm motion-type fit. Nutating Shaker (dimpled mat, this product) for tubes; Rocker (flat mat, B3D1008 sister) for trays / membranes — confirm intended workflow.
Confirm voltage and plug type. 115 V / 230 V chassis; a 230 V EU-plug configuration is available by special order at the same $484.
Confirm fixed-speed acceptability. B3D1020 is fixed-speed; for variable-speed tube-mixing, confirm whether a variable-speed sister exists in the B3D family at order.
Confirm at quote: voltage and plug type, intended motion-type fit (Nutating vs Rocker), platform size justification (Mini vs Standard), tube-format compatibility, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms — confirm at quote.
