The BSWBCT is the Blood Collection Combi-Block in the BSW block family — 20 total wells (12 × 13 mm + 8 × 16 mm) for mixed blood-tube format workflows — at $193 ($29 premium over the standard $164 BSW pricing). Designed for clinical / hematology workflows that handle both 13 mm and 16 mm OD blood tubes simultaneously — eliminating the need for separate single-format blocks (BSW13 + BSW1516) for mixed-tube-format workflows.
Key Specifications
| SKU | BSWBCT |
| Type | Blood Collection Combi-Block (dual blood-tube format) |
| Capacity | 12 × 13 mm OD tubes + 8 × 16 mm OD tubes (20 total positions) |
| Compatible chassis | Likely myBlock I/II — confirm with Benchmark Scientific |

| List price | $193 |
When to Pick the Combi-Block
Pick the BSWBCT when:
- Workflow processes both 13 mm and 16 mm blood tubes simultaneously (mixed clinical specimens)
- Clinical / hematology / serology workflows with mixed-OD blood tube formats
- Block-inventory consolidation — single combi-block instead of two single-format blocks
Pick BSW13 + BSW1516 separately ($164 each = $328 total) when simultaneous high-throughput of both formats is the workflow (combined gives 20+12 = 32 positions vs BSWBCT's 20).
Combi vs Two Single-Format Blocks
| Procurement | Cost | Total positions |
| BSWBCT (this product) | $193 | 20 (12+8) |
| BSW13 + BSW1516 | $328 | 32 (20+12) |
The combi-block is $193.00 cheaper than two single-format blocks but offers fewer total positions — pick by workflow throughput vs cost trade-off.
