The B2000-12 is the largest capacity in the Benchmark myBath Digital Water Bath family — 12 L water-bath capacity at $1,548, the right pick for multi-investigator shared throughput, production-scale incubation, and large-vessel pre-warming workflows. At $129/L, the 12 L bath is the most cost-efficient per-liter procurement in the myBath family — meaningful for facilities where total bath volume is a procurement driver. 115 V / 230 V chassis; the 230 V EU-plug configuration ships at the same $1,548 (by special order).

Why the 12 L Capacity — Shared-Facility / Production-Scale Workflows
The 12 L capacity is the right size for shared-facility and production-scale workflows — 20+ flasks at 50–250 mL simultaneously, production-scale enzyme-reaction batches (96-well plate arrays + multi-tube setups), large-vessel pre-warming (1 L+ media bottles, large-format reagent containers), and multi-investigator shared bath throughput where multiple users access the same bath across the workday.
Pick the myBath 12 L (B2000-12) when:
- Workflow is multi-investigator shared facility throughput — multiple users / multiple workflows running through the same bath
- Production-scale enzyme reactions — 96-well plate arrays + multi-tube setups simultaneously
- Large-vessel pre-warming — 1 L+ media bottles, large reagent containers, production-scale buffer prep
- Educational laboratory teaching at scale — large student-cohort exercises with high simultaneous bath access
- Cost-efficient per-liter procurement — $129/L is meaningfully more cost-efficient than the 4 L bath ($305/L) or 2 L bath ($367/L)
- Multi-cycler facility procurement — facilities benefit from one large shared bath vs multiple small baths
Stay with B2000-4 (4 L) when multi-flask but not multi-investigator workflows fit the bath capacity.
Stay with B2000-2 (2 L) when single-investigator small-vessel workflows are the routine.
Capacity Step Economics
| SKU | Capacity | List price | $/L | Cost-efficiency |
| B2000-2 | 2 L | $733 | $367/L | Highest $/L (matches small-vessel workflow) |
| B2000-4 | 4 L | $1,548.00 | $305/L | Mid $/L |
| B2000-12 (this product) | 12 L | $1,548 | $129/L | Lowest $/L — most cost-efficient bulk procurement |
The 12 L bath delivers 6× more working volume than the 2 L bath at only 2.1× the price — meaningful per-liter savings at scale.
Application Profile
Multi-investigator shared-facility throughput — core facilities, shared molecular biology labs, cell-culture facilities running daily multi-investigator water-bath workflows.
Production-scale enzyme reactions — high-volume enzyme-reaction setups including 96-well arrays, multi-rack tube setups simultaneously held at set point.
Large-vessel pre-warming workflows — cell-culture-room media-warming workflows for 500 mL – 1 L+ bottles before plating.
Educational laboratory teaching at scale — undergraduate / graduate program-wide procurement for large student-cohort exercises.
Hybridization at scale — multi-membrane Northern / Southern blot workflows requiring large bath capacity for multi-membrane simultaneous hybridization.
Method-development workflows — protocol-development at production-scale where smaller baths are throughput-limiting.
Multi-cycler facility procurement — facilities benefiting from one large shared bath vs multiple smaller baths (one large bath has lower facility footprint and lower total maintenance overhead).
Frequently Asked Questions
What is the capacity of the B2000-12? 12 L — the largest in the myBath Digital Water Bath family.
Is it cost-efficient per liter? Yes — at $129/L it is the most cost-efficient per-liter option in the family, versus $305/L (B2000-4) and $367/L (B2000-2).
What smaller capacities are available? B2000-2 (2 L, $733) and B2000-4 (4 L, $1,548.00).
What voltage does it use? 115 V or 230 V, 50–60 Hz (discrete variants); the 230 V version ships at the same $1,548 by special order.
How is temperature controlled? By digital microprocessor temperature control.
Ordering & Configuration
Pair with multi-flask / multi-rack bath accessories — confirm sizing for the larger working volume; multi-tier racks supporting parallel workflows.
Confirm voltage and plug type. 115 V / 230 V chassis; a 230 V EU-plug configuration is available by special order at the same $1,548.
Plan for facility-scale bath maintenance — larger water volumes require more frequent water-quality monitoring, biocide treatment, and periodic drain / clean / refill cycles.
Confirm bench-space and floor-space. The 12 L bath has substantially larger footprint than the 4 L or 2 L baths — confirm available facility space at order.
Confirm at quote: voltage and plug type, intended multi-investigator / production workflow plan, bath-accessory pairing, facility-space confirmation, water-quality protocol, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms — confirm at quote.
