The H3715 is the Multi-Functional 5-Position Hotplate Stirrer — Benchmark Scientific's 5-station benchtop hotplate stirrer at $1,195. NEW MULTI-POSITION FORMAT: 5 independent stirring positions on a single chassis — supports parallel solution preparation / mixing workflows. 115 V / 230 V chassis (120 V or 230 V per universe electrical; name labels "120V" reflecting legacy product convention).
SAFETY FLAG (caution): High-temperature surface burn hazard — same as the H3710 hotplate family. Operator PPE / bench-clearance / heat-resistant vessels required.
Author confidence note (MEDIUM) — name/electrical mismatch: Universe name says "120V" but electrical column says "120 or 230V, 50-60Hz" — same data quirk as the H2606 SureTemp Oven family (likely 115 V / 230 V chassis with legacy product name). Confirm exact voltage compatibility at order. No specific brochure in available corpus — confirm exact stir-position dimensions, individual-station temperature / speed control (independent vs ganged), and surface material with Benchmark Scientific tech support.
Voltage options: This unit can be ordered with European voltage requirements (230V/50Hz). Contact us to order.

Why a 5-Position Hotplate Stirrer
High-throughput solution-preparation workflows routinely require multiple parallel reactions / dissolutions / titrations at controlled temperature with stirring. Single-position hotplate stirrers force serial workflow (one solution at a time); a 5-position chassis runs 5 in parallel:
- Buffer-prep batch workflows — prep multiple buffers simultaneously
- Method-development workflows — temperature-or-speed sweep across 5 conditions in parallel
- Educational / teaching workflows — 5 student groups share one chassis at moderate cost
- QC labs — parallel lot-testing of multiple samples at controlled conditions
Pick the H3715 5-Position when:
- Workflow runs multiple parallel reactions / mixings routinely
- Educational lab with multi-group teaching workflow
- Bench-space efficiency — 5 stations in one footprint vs five separate chasses
- Cost efficiency — $1,195 single chassis vs ~$4,400 for five H3710-HS singles
Step down to H3710-HS single-position ($1,195.00) for single-station workflows at full 10 × 10" surface area.
Step down to H3770-HS smaller-format ($531) for single-station compact workflows.
Frequently Asked Questions
How many stirring positions does the H3715 have? 5 independent stirring positions on a single chassis.
What voltage and power does it require? 120 V or 230 V, 50–60 Hz, 500 W.
How does it compare in cost to buying single-position units? A single 5-position H3715 lists at $1,195 versus roughly $4,400 for five individual H3710-HS single-position stirrers.
Are the five stations independently controlled? This should be confirmed with Benchmark Scientific tech support — whether each station's temperature and speed is independently programmable or ganged is verified at order.
Are there safety considerations? Yes — the heated surfaces present a high-temperature burn hazard; operator PPE, bench clearance, and heat-resistant vessels are required.
Ordering & Configuration
Confirm independent vs ganged station control with Benchmark Scientific tech support — verify whether each station's temperature / speed is independently programmable or all 5 share a single controller.
Plan stir-bar inventory — 5 stations need 5 stir bars per workflow batch.
Plan bench clearance for radiated heat — 5-station chassis dissipates more heat than single-station; verify ventilation.
Confirm at quote: voltage / plug type, station-control programming, intended parallel workflow, stir-bar inventory, ventilation, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms.
