The BSH200-HL is the heated-lid variant of the myBlock Mini Dry Bath family, integrated heated lid above the sample block prevents tube-cap condensation during high-temperature workflows. Sold at $554 ($191 step over the standard BSH200 at $554.00). The heated-lid feature is borrowed from PCR thermal cycler design. It keeps tube-cap surface at sample temperature so water vapor doesn't condense on cap and drip back into the sample during cycle.

Why the Heated Lid: Condensation Control
In high-temperature dry-bath workflows (>65 °C, especially 95 °C denaturation):
- Sample interior is hot. Water vapor evaporates from sample
- Tube cap surface is cooler. Vapor condenses on cap
- Condensate drips back into sample. Dilutes reaction concentrations and produces inconsistent results
The heated lid keeps the cap surface at sample temperature, eliminating the temperature differential that causes condensation. Same engineering principle as PCR thermal cyclers, applied to dry bath workflows.
Pick the BSH200-HL (heated lid) when:
- Workflow involves high-temperature reactions (>65 °C, especially 95 °C denaturation)
- PCR-prep workflows outside thermal cycler. Denaturation, hot-start activation, melt-curve heating
- Concentration-sensitive reactions where condensate dilution would compromise results
- Method-development workflows where condensation effects must be eliminated
Stay with BSH200 standard ($554.00 no heated lid) when lower-temperature workflows (<65 °C) are the routine, condensation is minimal at moderate temperatures.
Step to BSH300 ($893) when cooling capability (sub-ambient temperatures) is the priority, different feature category.
Heated-Lid Compatibility Notes
| Block | Heated-lid compatibility | Notes |
| BSH100-15HL | Compatible, designed for heated-lid chassis | 15 × 1.5 mL Eppendorf with heated-lid optimization |
| BSH100-CV cuvette block | INCOMPATIBLE: cuvettes too tall for heated-lid clearance | Use cuvette block on standard chassis (BSH200, BSH1001) |
| Other BSH100-* blocks | Confirm with Benchmark Scientific tech support | Standard blocks may fit but heated-lid optimization varies |

Frequently Asked Questions
What does the heated lid do? It keeps the tube-cap surface at sample temperature, preventing condensation from forming on the cap and dripping back into the sample during high-temperature workflows.
How does the BSH200-HL compare to the standard BSH200? Same Mini dry-bath chassis plus the integrated heated lid; $554 versus $554.00 (a $191 step).
Which block should I pair with it? The BSH100-15HL heated-lid block ($124). Note the BSH100-CV cuvette block is incompatible. Cuvettes are too tall for the heated-lid clearance.
What voltage does it use? 100–240 V universal, 50 W.
Ordering & Configuration
Pair with BSH100-15HL heated-lid block. Confirm heated-lid block inventory at order. The heated-lid chassis is workflow-incomplete without compatible heated-lid block(s).
Confirm block-format compatibility. Some BSH100-* blocks may not be heated-lid compatible (e.g., BSH100-CV cuvette block is too tall). Confirm specific block compatibility at order.
Confirm voltage and plug type. Universal-input chassis.
Confirm bench-clearance for dual thermal hazard. Both block surface AND heated lid surface are hot during operation.
Confirm at quote: voltage / plug type, intended high-temperature workflow context, heated-lid block pairing, bench-clearance, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms.
myBlock Mini family:
- BSH200 / -E: Standard Mini ($554.00)
- BSH200-HL (this product): Heated-lid Mini ($554), high-temperature condensation control
- BSH300 / -E: Cooling Mini ($893)
Pick the heated-lid Mini for high-temperature workflows requiring condensation control; sister standard / cooling variants cover other workflow scenarios. Pair with BSH100-15HL heated-lid block for full workflow compatibility.
