LAUDA ECO E 10 S Precision Wide-Temperature Range Circulating Bath, 20–200 °C, ±0.01 °C Stability

Overview

The LAUDA ECO E 10 S is a precision-engineered, heating-only circulating bath designed for demanding laboratory applications requiring stable thermal control across an extended temperature range—from ambient (20 °C) up to 200 °C. Built upon LAUDA’s decades of expertise in thermal management systems, this unit employs resistive heating combined with a high-efficiency circulation pump and integrated cooling coil to enable rapid thermal equilibration and exceptional short-term stability of ±0.01 °C. Unlike basic immersion heaters or open-bath systems, the E 10 S operates as a closed-loop, forced-circulation system—ensuring uniform heat distribution throughout the stainless steel bath reservoir and enabling precise external temperature control of connected instruments (e.g., viscometers, spectrophotometer cells, reaction blocks, or material testing fixtures). Its Class III safety certification confirms suitability for use with both non-flammable and flammable heat transfer fluids—including silicone oils and specialized high-temperature synthetic media—making it compliant with IEC 61010-1 and widely accepted in GLP-compliant laboratories.

Key Features

• Stainless steel bath (11 L usable volume) rated for continuous operation up to 200 °C, with reinforced thermal insulation and rear-mounted drain valve for safe, tool-free fluid exchange.
• Integrated cooling coil standard—enabling active heat dissipation during ramp-down phases or when maintaining setpoints near upper temperature limits.
• Six-stage adjustable circulation pump (0–22 L/min), supporting both internal recirculation and external loop configurations without flow restriction or pressure loss.
• ECO Silver interface: monochrome LCD display with intuitive menu navigation, real-time parameter monitoring (setpoint, actual bath temperature, pump speed, status alerts), and programmable overtemperature protection with independent threshold setting.
• Standard USB port enables firmware updates and facilitates integration with optional interface modules—including Pt100/Libus for external sensor feedback or Command controller for centralized multi-device orchestration.
• Robust mechanical architecture includes IP20-rated enclosure, reinforced mounting points for external tubing, and CE/UKCA marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD).

Sample Compatibility & Compliance

The E 10 S accommodates a broad spectrum of heat transfer media—including water, aqueous glycol mixtures, silicone oils (e.g., DC200 series), and high-boiling-point synthetic fluids—subject to viscosity and flash point constraints defined in LAUDA’s approved fluid list. Its stainless steel bath and nickel-plated brass fittings ensure chemical compatibility with mildly aggressive solvents and long-term corrosion resistance. The device conforms to ISO/IEC 17025 requirements for equipment qualification when used in accredited testing laboratories. It supports audit-ready operation under GLP and GMP frameworks through configurable event logging (via optional software), user-accessible calibration offset adjustment, and traceable temperature verification using certified Pt100 probes. While not inherently FDA 21 CFR Part 11 compliant, its digital interface and external controller options allow integration into validated systems meeting electronic record and signature requirements.

Software & Data Management

The E 10 S operates autonomously via its embedded microcontroller but offers expandable connectivity. The standard USB interface permits local configuration and firmware upgrades using LAUDA’s PC-based ECO Configurator software (Windows-compatible). Optional Libus modules enable RS485 or Ethernet communication for integration into SCADA or LIMS environments. When paired with a Command controller, up to eight ECO units can be synchronized under a unified temperature profile scheduler—with individual ramp rates, hold times, and safety interlocks. All temperature logs—including setpoint deviations, pump status, and alarm events—are timestamped and exportable in CSV format. No cloud dependency or proprietary subscription is required; data sovereignty remains fully under user control.

Applications

This bath serves critical roles in analytical chemistry (e.g., HPLC column ovens, UV-Vis cuvette thermostating), polymer rheology (pre-heating test samples prior to rotational viscometry), pharmaceutical QC (dissolution apparatus temperature control per USP ), materials science (thermal aging studies of composites), and calibration labs (reference temperature source for probe validation). Its combination of wide range, fine stability, and external loop capability makes it especially valuable for applications where thermal inertia must be minimized—such as kinetic studies requiring rapid, repeatable temperature transitions—or where sample isolation from the bath environment is essential.

FAQ

Is the E 10 S suitable for use with flammable heat transfer fluids?
Yes—its Class III safety rating certifies safe operation with common flammable oils (e.g., Dow Corning 200 Fluid, Sigma-Aldrich Heat Transfer Oil), provided flash point exceeds operating temperature by ≥30 °C and proper ventilation is maintained.
Can the unit maintain temperature stability at 200 °C without external cooling?
While the integrated cooling coil aids in thermal recovery, sustained 200 °C operation requires adequate ambient airflow and avoidance of prolonged full-power heating cycles; stability specification applies under typical laboratory conditions (23 °C ambient, no direct solar load).
Does the USB interface support real-time data streaming?
No—the USB port is for configuration and firmware updates only; real-time telemetry requires optional Libus or Command controller interfaces.
What is the recommended recalibration interval?
LAUDA recommends annual verification against a NIST-traceable reference thermometer; internal Pt100 sensor offset can be adjusted via service menu after calibration.
Is the bath cover included with the E 10 S model?
No—the insulated bath cover is standard only on the E 4 variant; it is available as an accessory (Order No. 121002) for the E 10 S.
