The C3303-6HP is the Sprint 6H Plus — NEW product family of clinical-tier centrifuges with swing-out rotor design at $1,899. KEY DIFFERENTIATOR from the LC-8 family (fixed-angle rotors): swing-out rotor allows tubes to swing horizontal during centrifugation, producing a flat pellet at the tube bottom (vs the angled pellet from fixed-angle rotors). Critical for clinical hematology workflows (packed cell volume / hematocrit measurement, plasma / serum separation) where pellet visibility and aliquot pipetting accuracy depend on flat pellet geometry.

Why a Swing-Out Rotor — Clinical Hematology Workflows
Fixed-angle rotors (LC-8 family) hold tubes at a fixed tilt angle during centrifugation — pellet forms along the tube wall at the rotor angle, not at the tube bottom. Swing-out rotors (Sprint family) let tubes pivot to horizontal during centrifugation — pellet forms flat at the tube bottom as gravity / centrifugal force aligns vertically along tube length.
Flat pellet geometry matters for several clinical workflows: in clinical hematology, packed cell volume (hematocrit) measurement requires a flat cell layer for accurate volume reading; in plasma / serum separation, clean separation between the cell pellet and supernatant requires a flat phase boundary; aliquot pipetting accuracy improves because pipetting supernatant without disturbing the pellet is easier when the pellet is flat at the tube bottom rather than angled along the tube wall; and in density gradient centrifugation, flat layer geometry is critical for layer-based separation (Ficoll, Percoll workflows).
Pick the Sprint 6H Plus (C3303-6HP) when:
- Workflow is clinical hematology — hematocrit / packed cell volume / WBC differential
- Plasma / serum separation workflows
- Density gradient centrifugation (Ficoll / Percoll) and PBMC isolation — flat layer geometry required
- Pharmaceutical / clinical research with clinical sample-prep requirements
Stay with C3100 / C3200 LC-8 family for fixed-angle workflows where flat pellet geometry isn't required — substantial cost saving when fixed-angle is sufficient.

Frequently Asked Questions
What rotor is included with the C3303-6HP? A 6 × 15 mL swing-out rotor.
What is the difference between a swing-out and a fixed-angle rotor? A swing-out rotor lets tubes pivot to horizontal during the cycle, forming a flat pellet at the tube bottom; a fixed-angle rotor (the LC-8 family) holds tubes tilted, forming an angled pellet along the tube wall.
What workflows need a swing-out clinical centrifuge? Clinical hematology (hematocrit / packed cell volume), plasma / serum separation, density gradient centrifugation (Ficoll / Percoll), and PBMC isolation.
Can the C3303-6HP take a higher-capacity rotor? Yes — the optional C3303-1215 12 × 15 mL rotor ($282) is compatible.
What voltage and power does the C3303-6HP use? 115 V or 230 V, 50–60 Hz, 150 W.
Ordering & Configuration
Confirm voltage and plug type. 115 V / 230 V chassis; confirm EU plug variant with Benchmark Scientific.
Pair with optional 12 × 15 mL rotor (C3303-1215, $282) for higher-throughput workflows beyond the included 6-position rotor.
Plan rotor balance protocols — swing-out rotors require careful balance (paired tubes opposite each other) for safe operation.
Confirm at quote: voltage / plug type, intended clinical / hematology workflow context, optional rotor pairing, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms.
Centrifuge rotor type — fixed-angle vs swing-out:
- C3100 / C3200 LC-8 family — Fixed-angle rotor for general sample prep
- C3303-6HP Sprint 6H Plus (this product, $1,899) — Swing-out rotor for clinical hematology workflows
Pick the Sprint for clinical / hematology / density gradient workflows; sister LC-8 chasses cover general fixed-angle workflows at lower cost.
