MiniMixer 3D Nutating Shaker, Fixed Speed, 10.5×7.5" Platform with Dimpled Mat, 115 V

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.

Author confidence note (MEDIUM): No specific B3D1020 brochure in available corpus. Specs sourced from universe label. Confirm exact nutating angle, RPM, motor specifications, and dimpled-mat tube-format compatibility with Benchmark Scientific technical support.

Key Specifications

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.
