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 — 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.
