LAUDA Hydro H 5 V Evaporation Water Bath

Overview

The LAUDA Hydro H 5 V Evaporation Water Bath is a precision-engineered laboratory instrument designed for controlled, gentle solvent removal in analytical, synthetic, and preparative workflows. Operating on the principle of conductive heat transfer via a thermostatically regulated water medium, it enables reproducible evaporation at temperatures between 25 °C and 100 °C—well below thermal decomposition thresholds for many thermolabile compounds. Unlike open-flame or hotplate-based concentration methods, this unit eliminates direct contact heating and minimizes thermal gradients across sample vessels, thereby preserving molecular integrity during concentration, crystallization, or residue recovery steps. Its compact footprint and single-bath architecture make it suitable for benchtop integration in QC labs, R&D facilities, and teaching laboratories where space efficiency and operational safety are prioritized.

Key Features

• Stainless steel bath chamber, lid frame, bottom sieve plate, and heating element—ensuring long-term corrosion resistance and compliance with ISO 15190:2020 laboratory equipment material requirements.
• Adjustable ring-type bath cover composed of multiple interlocking polyphenylsulfone (PPSU) inserts—enabling secure, gap-free support for round-bottom flasks (14–100 mm diameter) and beakers without clamping mechanisms.
• Single-point analog temperature controller with calibrated dial scale—providing intuitive setpoint adjustment and stable thermal output within ±3 °C over the full operating range.
• Integrated low-level water detection system—automatically deactivating the heater when fluid volume falls below safe operational threshold, preventing dry-run damage and supporting unattended overnight operation.
• Dedicated mounting aperture in the lid frame—compatible with optional stainless steel support rods (e.g., Part No. A000039, Ø12 mm × 316 mm) for vertical fixture alignment of condensers or reflux apparatus.
• CE-marked power supply (230 V, 50/60 Hz) with 16 A circuit compatibility—designed for seamless integration into European and international mains infrastructure.

Sample Compatibility & Compliance

The H 5 V accommodates standard laboratory glassware including conical flasks (Erlenmeyer), round-bottom flasks, and beakers up to 1 L capacity. Its 192 mm bath opening and modular lid system ensure uniform heat distribution around vessel walls while minimizing vapor loss. The unit conforms to IEC 61010-1:2010 for electrical safety in laboratory environments and meets EN 60529 IP20 ingress protection standards. While not classified as GLP/GMP-critical instrumentation per se, its mechanical reliability, traceable temperature control, and absence of software-based calibration routines render it suitable for use in environments governed by ISO/IEC 17025:2017—particularly where method validation requires documented thermal stability and operator-independent operation.

Software & Data Management

The LAUDA Hydro H 5 V operates as a stand-alone analog device with no embedded microprocessor, firmware, or digital interface. Temperature is set and maintained exclusively via mechanical thermostat action—eliminating dependency on software updates, cybersecurity protocols, or electronic data logging. This architecture ensures intrinsic compliance with FDA 21 CFR Part 11 requirements for systems where audit trails are not mandated, and supports laboratories seeking minimal validation burden for auxiliary thermal equipment. All operational parameters—including setpoint, bath volume, and ambient conditions—are manually recorded per SOP-defined log sheets, aligning with traditional paper-based GLP documentation practices.

Applications

• Routine solvent evaporation in organic synthesis workups prior to NMR or MS analysis.
• Concentration of aqueous extracts in natural product isolation and phytochemical screening.
• Preparative drying of precipitated salts or crystalline intermediates under inert atmosphere (when used with condenser assemblies).
• Controlled dehydration of biological samples in histology or microbiology sample preparation.
• Standardized evaporation protocols compliant with ASTM D129-18 (petroleum products) and USP <721> (residue on evaporation testing).

FAQ

Does the H 5 V support external temperature probes or digital PID control?
No. It features a fixed single-point analog thermostat only—no RS-232, USB, or analog output interfaces are provided.
Can the bath be filled with liquids other than deionized water?
Only water or water-glycol mixtures (≤30% v/v) are recommended; aggressive solvents or acids may compromise seal integrity and stainless steel passivation.
Is the unit suitable for vacuum-assisted evaporation?
Yes—when paired with appropriate vacuum-compatible glassware and external vacuum sources; however, bath pressure equilibrium must be monitored to prevent cavitation or boiling point depression-induced instability.
What maintenance is required to sustain accuracy and longevity?
Monthly visual inspection of water level sensor contacts, quarterly descaling using 5% citric acid solution, and annual verification of thermostat calibration against a traceable NIST-certified thermometer.
Does LAUDA provide IQ/OQ documentation for this model?
Factory-issued installation and operational qualification templates are available upon request for GxP-regulated sites, though final execution remains the responsibility of the end-user’s qualified personnel.
