The BSH1004 is the four-position Benchmark Digital Dry Bath — accepts four blocks simultaneously (vs single-position BSH1001 and dual-position BSH1002) — at $1,118. Largest chassis in the BSH dry bath family. Likely supports independent temperature control per block (4 simultaneous temperatures), making it the facility-scale multi-protocol shared chassis: 4 investigators / 4 protocols / 4 temperature setpoints simultaneously in one chassis.
Author confidence note (MEDIUM): No specific BSH1004 brochure in available corpus. Specs sourced from universe label. Confirm independent-temperature-per-block control with Benchmark Scientific technical support — independent control across 4 blocks is the key workflow differentiator that justifies the chassis premium.

Why Four Position — Facility-Scale Multi-Protocol Workflows
The four-position chassis is the facility-scale multi-protocol dry bath, supporting workflows that exceed dual-position capacity: 4-temperature enzyme-cascade protocols requiring multiple simultaneous setpoints, multi-investigator shared facilities running four investigators' workflows in one chassis, multi-protocol comparison work that runs four temperatures or protocols side by side, multi-tube-format workflows with four different block formats at once (e.g., PCR + 0.5 mL + 1.5 mL + 15 mL), and production-scale enzyme prep consolidating multi-step reactions onto one chassis.
Pick the BSH1004 (four position) when:
- Workflow involves 4-temperature simultaneous workflows at facility scale
- Multi-investigator shared facility procurement consolidating 4 workflows onto one chassis
- Multi-tube-format flexibility — 4 different blocks simultaneously
- Cost-efficient multi-protocol procurement vs procuring 4 single-position chasses ($580 × 4 = $2,320 vs $1,118 four-position = $1,202 savings)
Stay with BSH1002 dual position ($1,118.00) when 2-block / 2-temperature workflows match the routine.
Stay with BSH1001 single position ($580) when single-protocol workflows are the only routine.

| SKU | Block positions | List price |
| BSH1001 / -E | 1 | $580 |
| BSH1002 / -E | 2 (dual) | $1,118.00 |

Capacity Step Economics
| Procurement option | Block positions | Total cost |
| 1× BSH1001 single | 1 | $580 |
| 1× BSH1002 dual | 2 | $1,118.00 |
| 2× BSH1001 (parallel) | 2 | $1,160 |
| 1× BSH1004 four (this product) | 4 | $1,118 |
| 2× BSH1002 dual (parallel) | 4 | $1,446 |
| 4× BSH1001 (parallel) | 4 | $2,320 |
Four-position dry bath at $1,118 is meaningfully more cost-efficient than procuring multiple smaller chasses to reach the same total block capacity — $1,202 savings vs four singles, $328 savings vs two duals.

Frequently Asked Questions
How many blocks does the BSH1004 hold? Four blocks simultaneously — the largest chassis in the BSH dry bath family, versus the single-position BSH1001 and dual-position BSH1002.
Does the BSH1004 include blocks? No — the $1,118 price is for the chassis only; blocks from the BSH100-* family are ordered separately.
Does each position control temperature independently? The four-position design likely supports independent temperature per block, but this should be confirmed with Benchmark Scientific tech support before purchase.
What voltage does the BSH1004 use? 120 V or 230 V at 50–60 Hz (discrete variants).
Is the BSH1004 more cost-efficient than multiple smaller dry baths? Yes — at $1,118 it is $1,202 less than four BSH1001 singles ($2,320) and $328 less than two BSH1002 duals ($1,446) for the same four-block capacity.
Ordering & Configuration
Confirm independent-temperature-per-block control. Critical: confirm with Benchmark Scientific tech support whether all 4 block positions support independent temperature setpoints (typical four-position dry bath design) or have shared / paired temperature zones.
Pair chassis with up to 4 blocks at first procurement. Four-position chassis is workflow-incomplete with fewer than the full block complement; recommend procurement of 4 blocks matched to intended workflow tube formats (or 4 of the same block for multi-investigator shared facility throughput).
Confirm voltage and plug type. 115 V / 230 V chassis.
Confirm bench-clearance for thermal envelope. Four-block surface area is substantially larger than single / dual chasses.
Confirm at quote: voltage / plug type, intended multi-temperature / multi-protocol workflow, independent-temperature confirmation, block-pairing inventory plan (up to 4 blocks), bench-clearance, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms — confirm at quote.
BSH dry bath family — pick the right capacity:
- BSH1001 / -E — Single position ($580) — single-protocol routine
- BSH1002 / -E — Dual position ($1,118.00) — multi-temperature dual workflows
- BSH1004 / -E (this product) — Four position ($1,118) — facility-scale multi-protocol / multi-investigator workflows
Pick the four-position chassis for facility-scale multi-protocol workflows at the most cost-efficient $/block-position; sister single / dual cover smaller-throughput workflows. See BSH1001 anchor for full BSH family chemistry / block-selection detail.
