The BSH100-15HL is the heated-lid-compatible variant of the standard 1.5 mL Eppendorf block — 15 wells for 1.5 mL Eppendorf tubes, designed for heated-lid chassis variants of the BSH dry bath family. Sold at $124 (same price as the standard BSH100-15). The heated-lid feature (similar to a PCR thermal cycler's heated lid) prevents condensation on tube caps during high-temperature workflows — important for workflows where condensate would dilute samples or compromise reaction concentrations.
Author confidence note (MEDIUM): Universe doesn't enumerate the specific heated-lid chassis SKUs that pair with this block. Confirm compatible heated-lid chassis with Benchmark Scientific technical support before procurement — the heated-lid feature is a chassis-level capability that requires a chassis variant supporting heated-lid operation.

Why a Heated-Lid-Compatible Block
Heated lids are a workflow feature borrowed from PCR thermal cyclers: a heated cover above the sample block that prevents condensation on tube caps. During high-temperature workflows (e.g., 95 °C denaturation, hot-start enzymatic activation), water vapor inside tubes would otherwise:
- Condense on tube caps during cycle (tube interior is hot, cap is cooler)
- Drip back into the sample, diluting the reaction, or migrate to other tubes as cross-contamination
The heated lid keeps the cap surface at sample temperature, preventing condensation and maintaining reaction integrity.
The HL block variant is mechanically optimized for heated-lid operation — likely with specific tube-well geometry that creates good thermal contact with the heated lid covering the block.
Pick the BSH100-15HL when:
- Workflow uses heated-lid chassis for high-temperature workflows
- High-temperature reactions (>65 °C) where condensation matters
- Concentration-sensitive workflows where condensate dilution would compromise results
- PCR-prep workflows outside thermal cycler where heated-lid functionality is needed
Pick BSH100-15 (standard, no HL) for routine 1.5 mL Eppendorf workflows at standard temperatures where heated-lid functionality isn't required — same $124 price, simpler workflow integration.
Ordering & Configuration
Confirm heated-lid chassis compatibility. This block is sized for heated-lid chassis specifically — confirm chassis SKU compatibility with Benchmark Scientific tech support before procurement.
Pair with heated-lid chassis. Block is workflow-incomplete without a compatible chassis.
Confirm at quote: heated-lid chassis pairing, intended high-temperature workflow context, and lead time.
Warranty: Per Benchmark Scientific standard accessory terms.
BSH 1.5 mL block variants:
- BSH100-15 — Standard 1.5 mL block ($124) — for standard BSH dry bath chassis
- BSH100-15HL (this product) — 1.5 mL block for heated-lid chassis ($124) — high-temperature condensation control
Pick the heated-lid block for high-temperature workflows requiring condensation control on heated-lid chassis variants; sister standard block covers standard temperature workflows. See BSH1001 anchor for full BSH family / block selection detail.
