Grant SBB AQUA PLUS Series Boiling Water Bath

Overview

The Grant SBB AQUA PLUS Series Boiling Water Bath is an engineered thermal platform designed for precise, sustained boiling applications in analytical, pharmaceutical, microbiological, and quality control laboratories. Unlike conventional water baths relying on simple thermostatic control, the SBB AQUA PLUS series incorporates a dedicated analog power regulation system that maintains continuous, stable boiling—without thermal overshoot or cycling—by dynamically adjusting heating energy output. This capability is critical for procedures requiring consistent vapor-phase exposure, uniform heat transfer across sample vessels, or prolonged sterilization of media and glassware. The unit operates within a calibrated temperature range from ambient +5 °C up to 100 °C, with full boiling functionality verified at atmospheric pressure. Its stainless steel tank construction, corrosion-resistant internal surfaces, and rigid structural frame ensure long-term mechanical integrity under daily laboratory use.

Key Features

• Stable Boiling Mode: Analog power modulation enables reproducible, uninterrupted boiling—essential for depyrogenation, enzymatic inactivation, and solvent evaporation protocols.
• Constant Liquid Level System: Integrated float-controlled fill mechanism compensates for evaporation loss, maintaining consistent immersion depth and thermal uniformity across all operating durations.
• Rugged Industrial Design: Reinforced 304 stainless steel bath tank, heavy-duty support frame, and IP22-rated electrical housing provide resistance to mechanical stress, chemical splash, and extended operational duty cycles.
• Configurable Capacity Options: Four standard models (5 L, 12 L, 18 L, and 26 L) accommodate varying throughput demands—from single-vial processing to multi-rack incubation of culture tubes or flasks.
• Safety-Engineered Protection: Adjustable over-temperature cut-off (OTC) independently monitors bath temperature and interrupts power if preset limits are exceeded—compliant with IEC 61010-1 requirements for laboratory equipment safety.
• Standard Drip-Resistant Polycarbonate Lid: Minimizes condensate ingress into samples while permitting visual monitoring and controlled access; lid design conforms to ISO 15195:2013 recommendations for open-bath containment.

Sample Compatibility & Compliance

The SBB AQUA PLUS accommodates standard laboratory glassware including borosilicate test tubes (12–25 mm OD), conical flasks (up to 1 L), Petri dish stacks, and autoclave baskets. Its uniform temperature distribution—verified per ASTM E1112—ensures ±0.5 °C spatial consistency across the working volume at 100 °C. Units are supplied with CE marking and comply with EN 61010-1:2010+A1:2013 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use). For regulated environments, the analog control architecture supports documented calibration traceability to UKAS-accredited standards; optional calibration certificates (ISO/IEC 17025) are available upon request. While not inherently 21 CFR Part 11 compliant due to analog operation, the system may be integrated into validated workflows where manual log entries and procedural controls satisfy GLP/GMP documentation requirements.

Software & Data Management

The SBB AQUA PLUS operates via analog control without embedded digital firmware or connectivity interfaces. Temperature setpoint and power output are adjusted manually using front-panel potentiometers, eliminating software dependencies and reducing validation burden in regulated labs. All operational parameters—including setpoint, duration, and OTC threshold—are recorded manually in lab notebooks or electronic batch records. For users requiring data capture, third-party external temperature loggers (e.g., compliant with ASTM E2810) may be deployed with NIST-traceable probes placed directly in the bath medium. Grant provides full technical documentation—including wiring diagrams, maintenance schedules, and calibration guidance—in English, aligned with ISO/IEC 17025 clause 7.6 on equipment verification.

Applications

• Media preparation and sterilization in microbiology labs (e.g., nutrient broth activation, agar dissolution).
• Depyrogenation of glassware and stainless-steel components prior to aseptic processing.
• Controlled boiling of aqueous reagents during titration standardization or reference material preparation.
• Thermal equilibration of calibration standards for viscometers, densitometers, and refractometers.
• Supporting USP and environmental controls for non-sterile compounding preparation areas.
• Long-duration hydrolysis studies in analytical chemistry where constant 100 °C exposure is required.

FAQ

Does the SBB AQUA PLUS support programmable ramping or digital temperature logging?
No. It features analog regulation only—ideal for applications requiring simplicity, reliability, and minimal validation overhead.
Can the unit operate continuously for 72+ hours?
Yes. Designed for unattended operation, it meets IEC 60335-1 endurance criteria when maintained per Grant’s service schedule.
Is the polycarbonate lid autoclavable?
No. It is rated for repeated hot-water cleaning only; autoclaving will deform the material.
What is the recommended calibration frequency?
Annual calibration is advised; more frequent checks are required if used in GxP environments or following any physical impact or thermal shock event.
Are replacement heating elements field-serviceable?
Yes. All SBB AQUA PLUS models use modular, user-replaceable heating assemblies with standardized M12 connectors and documented torque specifications.
