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. It 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.
