The B2023-10 is the myBath CR Circulating Water Bath — a 10 L circulating bath with pump-driven external circulation for remote-vessel temperature control workflows, sold at $1,289. Distinct product family from the myBath Digital (non-circulating) Water Baths (B2000 family) — the CR (Circulating) designation marks the pump-driven external loop capability that enables temperature control of items outside the bath chamber: jacketed reaction vessels, circulating heat exchangers, attached temperature-controlled stages, and other external-loop temperature-control workflows.

Universe label note: the universe SKU name field reads "myBath CR Circulating Water Bath, 10 L, 115 V" — the "115 V" portion of the name is treated as part of the SKU description here (not as a separate spec). A 230 V EU-plug configuration is available at $1,289.
Voltage options: This unit can be ordered with European voltage requirements (230V/50Hz). Contact us to order.

Why a Circulating Water Bath — External-Loop Workflows
The myBath Digital (B2000) family is non-circulating — water is heated to set point and held there, but the water doesn't move beyond the bath chamber. Items must be immersed directly in the bath water for temperature control.
The myBath CR (B2023) family is circulating — a pump drives external circulation through tubing connections, allowing temperature control of items outside the bath:
| Workflow | Non-circulating (B2000) | Circulating (B2023, this family) |
| In-bath sample warming (flasks, tubes) | Yes — workhorse application | Yes (compatible) |
| Jacketed reaction vessel temperature control | No — vessel must be immersed | Yes — circulate through vessel jacket |
| Heat exchanger / cold trap circulation | No | Yes — circulate through heat exchanger |
| Microscope-stage temperature control | No | Yes — circulate through stage loop |
| Custom external-loop apparatus | No | Yes — pump-driven loop |
| Distance temperature control | No | Yes — bath can be located away from the apparatus |
Pick the myBath CR Circulating (B2023-10) when:
- Workflow uses jacketed reaction vessels (chemistry / biology reactions in jacketed glassware requiring temperature-controlled liquid through the jacket)
- Microscope-stage temperature control for live-cell imaging or temperature-stage microscopy
- Heat exchanger workflows — circulate temperature-controlled water through external heat exchangers
- Custom apparatus temperature control — any workflow requiring temperature-controlled liquid circulation outside the bath chamber
- Distance temperature control — the bath sits in one location while the controlled apparatus sits elsewhere on the bench
Pick the myBath Digital (B2000) family when direct in-bath immersion of flasks / tubes / racks is the workflow — the simpler non-circulating family at lower price.
Circulating vs Non-Circulating — Key Workflow Distinctions
| Feature | myBath Digital (B2000) | myBath CR (B2023, this family) |
| Pump for external circulation | None | Yes — pump-driven external loop |
| External tubing connections | None | Yes — input / return tubing for external loop |
| In-bath sample workflows | Workhorse | Compatible |
| External-loop apparatus workflows | Not supported | Workhorse |
| Bath capacity (this size) | 2 L / 4 L / 8 L / 12 L options | 10 L |
| List price (10–12 L range) | $1,548 (12 L digital) | $1,289 (10 L circulating) |
Application Profile
Jacketed reaction vessel temperature control — synthetic chemistry, biology reactions in jacketed glassware (jacketed flask / jacketed reactor) requiring controlled-temperature circulation through the jacket.
Microscope-stage temperature control — live-cell imaging, temperature-stage microscopy, slide-warmer microscope workflows.
External heat exchanger workflows — circulating temperature-controlled water through heat exchangers for cold-trap protection, sample-line temperature control, downstream-instrument temperature management.
Custom apparatus temperature control — custom-built bench apparatus requiring external temperature-controlled liquid loop.
Distance temperature control — bath sits in one location, apparatus elsewhere; circulation tubing carries temperature-controlled water across the bench.
Method-development workflows — protocol-development requiring external-loop temperature control where in-bath immersion is impractical.
Multi-cycler facility procurement — facilities procuring temperature-control infrastructure for jacketed-vessel chemistry / biology workflows.
Frequently Asked Questions
What does the "CR" in myBath CR mean? Circulating — the B2023 family has a pump-driven external loop that enables temperature control of items outside the bath chamber, unlike the non-circulating myBath Digital (B2000) family.
What is the bath capacity of the B2023-10? 10 L.
What workflows is a circulating bath used for? Jacketed reaction vessels, external heat exchangers or cold traps, microscope-stage temperature control, and other external-loop or distance temperature-control workflows.
When should I choose the myBath Digital instead? When the workflow is direct in-bath immersion of flasks, tubes, or racks — the simpler non-circulating B2000 family covers that.
What voltage does the B2023-10 use? 115 V (US plug); a 230 V EU-plug configuration is available by special order at the same $1,289.
Ordering & Configuration
Pair with external tubing and apparatus. Confirm tubing inlet / outlet connection sizing at order — external-loop workflows require specific tubing-fit hardware at the bath connection points. Confirm the apparatus tubing-port standard matches.
Confirm pump flow rate vs apparatus requirement. External-loop apparatus may have minimum / maximum flow-rate tolerances. Confirm bath pump flow rate matches workflow requirement — particularly for jacketed reaction vessels and heat exchangers with specific flow-rate specs.
Confirm temperature range for workflow. Standard circulating water baths cover ambient to ~95 °C. For sub-ambient temperature workflows (cell-culture media chilling, cold-temperature reactions), confirm whether the bath includes refrigeration capability or whether a separate chiller is needed.
Confirm voltage and plug type. B2023-10 = 115 V US plug; a 230 V EU-plug configuration is available by special order ($1,289).
Confirm at quote: voltage and plug type, intended external-loop workflow (jacketed vessel / microscope stage / heat exchanger / custom apparatus), pump flow-rate fit, tubing connection compatibility, temperature range requirement, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms — confirm at quote.
Benchmark Scientific water bath families — pick the right type:
