The H2505-40 is the SureTemp Dual Convection Incubator — Benchmark Scientific's 40 L benchtop convection incubator at $2,380. NEW PRODUCT FAMILY: SureTemp dual convection incubators. KEY DIFFERENTIATOR: dual convection mode — combines gravity-driven and forced-air convection for superior temperature uniformity across the chamber. Sister 130 L variant H2505-130 at $3,922. Same-price EU pair H2505-40E ($2,380) — note the EU variant bundles SureTemp Data Logging Software per universe label.
Author confidence note (MEDIUM): No specific SureTemp Dual Convection brochure in available corpus. Confirm exact temperature range, temperature uniformity (±X °C across chamber), convection-mode switching mechanism (manual vs auto), and whether the US variant (this SKU) supports SureTemp Data Logging Software as an add-on (the EU sister H2505-40E bundles it at no price differential — unusual). Confirm with Benchmark Scientific tech support.
Voltage options: This unit can be ordered with European voltage requirements (230V/50Hz). Contact us to order.

Why Dual Convection
Convection mode determines temperature uniformity across the incubator chamber:
- Gravity-driven convection (no fan): gentle airflow from natural temperature gradient. Lower air movement → less drying of plate cultures, less disturbance of light samples. Lower temperature uniformity at large chamber volumes.
- Forced-air convection (with fan): active fan drives air circulation. Higher temperature uniformity across chamber. More disturbance of light samples / increased evaporation from open dishes.
SureTemp dual convection allows the operator to switch modes per workflow — gravity for light/dry samples, forced for production-uniform incubation.
Pick the H2505-40 SureTemp 40 L when:
- Mixed convection-mode workflow — different protocols benefit from different modes
- Temperature-uniformity-critical workflows — forced-air mode gives publishable uniformity specifications
- Bench-scale 40 L workflows — moderate-throughput dedicated incubator
- Method-development workflows that benefit from convection-mode flexibility
Step up to H2505-130 (130 L, $3,922) for higher-throughput / larger-vessel workflows at production scale.
Pick myTemp Mini / 65 family instead when single-convection-mode workflow is established and dual-convection flexibility isn't needed.

Frequently Asked Questions
Q: What is "dual convection"? A: The incubator combines gravity-driven and forced-air convection, letting the operator switch modes per workflow — gravity for light or dry samples, forced-air for production-uniform incubation.
Q: What chamber size is the H2505-40? A: 40 L. The larger sister H2505-130 offers 130 L at $3,922.
Q: Does the H2505-40 include SureTemp Data Logging Software? A: The EU sister H2505-40E bundles it at the same $2,380; confirm whether the US variant includes it or requires separate procurement with Benchmark Scientific.
Q: Can it run on 230V? A: Yes — 120V or 230V, 50–60Hz; a 230V/50Hz configuration is available by special order.
