Benchmark MyBath B2000 Series Digital Water Bath

Overview

The Benchmark MyBath B2000 Series Digital Water Bath is a precision-engineered temperature-controlled immersion system designed for consistent thermal stabilization of samples in life science, clinical, and quality control laboratories. Operating on the principle of convective heat transfer through a thermally uniform water medium, the B2000 series delivers stable, repeatable heating across its full operating range (ambient +5°C to 100°C). Its compact footprint, seamless stainless steel chamber, and digital PID temperature controller enable high reproducibility in applications requiring tight thermal tolerances—particularly critical in enzyme assays, cell culture warm-up, reagent equilibration, and sample thawing protocols where thermal overshoot or gradient-induced variability must be minimized.

Key Features

• Digital PID temperature control with 0.1°C resolution and intuitive 3-inch LED display for real-time monitoring and precise setpoint adjustment.
• Fast calibration mode allows user-initiated offset correction without external instrumentation—fully compliant with internal verification procedures per ISO/IEC 17025 Clause 7.7.
• Thermally insulated housing minimizes surface temperature rise (<45°C at ambient 25°C), enhancing operator safety and reducing ambient heat load in shared lab environments.
• Seamless 304 stainless steel chamber eliminates crevices and weld seams, preventing biofilm accumulation and enabling rapid, residue-free cleaning—validated for compatibility with common laboratory disinfectants (e.g., 70% ethanol, 0.5% sodium hypochlorite).
• Angled transparent acrylic lid directs condensate toward front/rear edges, preventing droplet contamination of samples or tube interiors—a design validated under ISO 13485 environmental control requirements for medical device manufacturing support labs.
• Integrated drain valve (standard on 8 L and 12 L models) facilitates rapid, spill-free water exchange during routine maintenance or protocol changes.

Sample Compatibility & Compliance

The MyBath B2000 accommodates standard laboratory vessels including microcentrifuge tubes (1.5/2 mL), conical centrifuge tubes (15 mL and 50 mL), and glass/plastic beakers up to 100 mm diameter. Removable, autoclavable tube racks (supplied complete with B2000-4*) are engineered to maintain vertical alignment and minimize vibration-induced sample disturbance. All models meet UL 61010-1 and IEC 61010-1 safety standards for laboratory electrical equipment. The unit’s thermal performance is characterized per ASTM E2219–22 (Standard Practice for Calibration and Verification of Liquid Baths), supporting traceable validation documentation required for GLP and GMP environments.

Software & Data Management

While the B2000 operates as a standalone analog-digital hybrid instrument, its temperature setpoint and real-time reading are accessible via optional RS-232 interface (available as accessory kit). When integrated with Benchmark’s LabLink™ software suite (v3.2+), users can log time-stamped temperature profiles, generate audit-trail reports compliant with FDA 21 CFR Part 11, and export CSV-formatted data for statistical process control (SPC) analysis. Internal memory retains last-used parameters across power cycles, supporting continuity in regulated workflows where configuration drift must be controlled.

Applications

• Pre-warming culture media and reagents prior to cell passaging or microbial inoculation.
• Controlled thawing of cryopreserved biologicals (e.g., PBMCs, primary neurons) to mitigate thermal shock.
• Enzyme kinetic studies requiring strict thermal consistency across reaction replicates.
• Calibration of temperature-sensitive sensors (e.g., thermistors, RTDs) using NIST-traceable reference baths.
• Supporting ASTM D92 (Cleveland Open Cup) and ASTM D93 (Pensky-Martens) flash point testing as auxiliary heating stage.
• Hybridization incubation in molecular diagnostics workflows adhering to CLIA and CAP requirements.

FAQ

Is the MyBath B2000 suitable for use with flammable solvents?

No. This unit is designed exclusively for aqueous media. Use only deionized or distilled water; never organic solvents, oils, or corrosive liquids.
Can the temperature calibration be adjusted by the end user?

Yes. The built-in quick-calibration function permits manual offset adjustment within ±2.0°C, documented in the operator log per ISO/IEC 17025 Section 7.7.2.
What is the recommended maintenance interval?

Perform visual inspection and chamber cleaning after each use; conduct full thermal validation annually or per SOP-defined frequency, especially in regulated environments.
Are replacement lids and tube racks available as spare parts?

Yes. OEM-certified components—including angled acrylic lids (P/N MB-LID-4L), 50-mL rack inserts (P/N MB-RACK-50), and drain valve assemblies (P/N MB-DRAIN-KIT)—are stocked globally.
Does the B2000 series support remote monitoring via Ethernet or Wi-Fi?

Not natively. Remote capability requires the optional RS-232-to-Ethernet converter (P/N BMK-ETH-ADAP) and LabLink™ software integration.
