Block, 15 × 1.5 mL / 2.0 mL Tubes

The BSH100-1520 is the dual-format Eppendorf block for the BSH digital dry bath family — 15 wells that accept BOTH 1.5 mL AND 2.0 mL Eppendorf tubes in the same wells —. Workflow-flexibility advantage: single block supports both common Eppendorf tube formats, eliminating the need for separate dedicated blocks for each format.

For full chemistry rationale, see the BSH1001 (chassis) anchor page.

Key Specifications

Why a Dual-Format Block

Many molecular biology workflows mix 1.5 mL and 2.0 mL Eppendorf tubes:

• 1.5 mL for small-volume reactions, working aliquots
• 2.0 mL for slightly-larger-volume reactions, sample-prep stocks

The standard BSH100-15 (1.5 mL only) requires a separate block for 2.0 mL workflows if both formats are routine. The BSH100-1520 eliminates this dual-block procurement — single block accepts either format in the same wells.

Pick the BSH100-1520 when:

• Workflow routinely uses both 1.5 mL AND 2.0 mL Eppendorf tubes
• Reduced block inventory is a procurement strategy
• Multi-investigator shared chassis where investigators use both Eppendorf formats
• Method-development workflows comparing reactions across tube formats

Pick the BSH100-15 single-format block when only 1.5 mL workflows are routine — no advantage to dual-format if 2.0 mL isn't used.

BSH 1.5 mL Eppendorf block variants:

- BSH100-15 — 1.5 mL only

- BSH100-1520 (this product) — 1.5 mL or 2.0 mL dual-format — workflow-flexibility for mixed Eppendorf formats

- BSH100-15HL — 1.5 mL for heated-lid chassis

Pick the dual-format block when both 1.5 mL and 2.0 mL Eppendorf tubes are workflow-routine; sister single-format and heated-lid variants cover specific workflow scenarios. See BSH1001 anchor for full block-family detail.
