Tamson TC16/TC40/TC58 Precision Constant-Temperature Circulating Bath

Overview

The Tamson TC16, TC40, and TC58 are high-precision, heating-only constant-temperature circulating baths engineered for demanding laboratory applications requiring exceptional thermal stability and long-term operational reliability. Designed and manufactured in the Netherlands, these baths employ a robust stainless-steel reservoir combined with a high-efficiency immersion heater and a precisely calibrated platinum resistance thermometer (PT100) sensor. Temperature regulation is achieved via PID (Proportional–Integral–Derivative) feedback control, enabling stable setpoint maintenance within ±0.02 °C across the full operating range—from ambient up to 250 °C. Unlike open-bath systems, the TC series integrates an internal recirculation pump that ensures uniform temperature distribution throughout the bath fluid (water, silicone oil, or heat-transfer fluids), minimizing axial and radial gradients. This architecture supports consistent thermal conditioning of external equipment—such as viscometers, spectrophotometer cells, reaction blocks, or calibration standards—without requiring external plumbing or auxiliary chillers.

Key Features

• Three standard bath volumes (16 L, 40 L, 58 L) to match application scale and thermal mass requirements
• High-stability PID temperature controller with real-time digital display and intuitive front-panel interface
• Internal recirculation system delivering laminar, low-turbulence flow—optimized for minimal vibration transfer to sensitive instruments
• CE-compliant electrical design with dual-layer safety: primary electronic temperature limiter + independent mechanical resettable safety thermostat
• RS232 serial interface enabling remote monitoring, setpoint adjustment, and time-stamped data acquisition
• Free Tamcom software for Windows-based configuration, real-time graphing, automated logging, and export to CSV or Excel formats
• Optional °F unit output available upon request; default display and control in °C per IEC 60068-3-5 and ISO 17025 traceable calibration practices

Sample Compatibility & Compliance

These baths accommodate a broad range of immersion-compatible sample holders, probe sleeves, and external apparatus—including glassware, metal blocks, jacketed reactors, and analytical instrument thermostats. The reservoirs are constructed from electropolished 316 stainless steel, ensuring chemical resistance to water, glycols, silicone oils (up to 250 °C), and mineral oils. All models conform to EN 61000-6-3 (EMC emissions) and EN 61000-6-2 (immunity), and carry full CE marking under the Low Voltage Directive (2014/35/EU) and Electromagnetic Compatibility Directive (2014/30/EU). The integrated mechanical safety thermostat complies with EN 60519-2 for industrial heating equipment, providing fail-safe cut-off independent of electronic control circuitry. While not intrinsically rated for hazardous locations, units may be operated in Class 1000 cleanrooms when fitted with optional HEPA-filtered air intakes.

Software & Data Management

Tamcom software provides full bidirectional communication with the bath controller via RS232. It supports multi-channel logging (temperature, setpoint, elapsed time), user-defined alarm thresholds, and audit-trail generation compliant with GLP and FDA 21 CFR Part 11 requirements when used with appropriate system validation protocols. Data files include embedded metadata (operator ID, instrument serial number, calibration date), support timestamped export, and allow interpolation-free linear regression analysis for stability assessment over extended periods. No cloud dependency or subscription model—the software is locally installed and fully functional offline.

Applications

• Calibration of thermometers, RTDs, and thermocouples per ASTM E74 and ISO/IEC 17025
• Thermal preconditioning of polymer melts prior to rheological testing (ASTM D3835)
• Stabilization of optical components in UV-Vis and FTIR spectroscopy
• Controlled heating of solvent baths for Soxhlet extraction or reflux setups
• Temperature-dependent viscosity measurements using rotational or capillary viscometers
• Accelerated aging studies in materials science and pharmaceutical stability testing (ICH Q1A)

FAQ

Can the TC series be used with silicone oil at 250 °C without degradation?
Yes—provided the oil meets ASTM D4692 specifications for high-temperature synthetic heat-transfer fluids and is changed per manufacturer-recommended intervals (typically every 6–12 months under continuous operation).
Is external cooling capability available?
No—the TC series is strictly heating-only. For sub-ambient or dual-range control, Tamson offers the TCW series with integrated refrigeration.
Does Tamcom software support automated report generation for quality audits?
Yes—customizable templates can be configured to generate PDF reports including raw data tables, trend plots, pass/fail annotations against SOP-defined tolerances, and electronic signature fields.
What is the maximum recommended fill level for optimal circulation and temperature uniformity?
For all models, maintain fluid level between 20% and 90% of rated volume to ensure proper pump priming and avoid cavitation or overflow during thermal expansion.
Are calibration certificates included with shipment?
A factory-as-tested certificate of conformance is supplied. NIST-traceable calibration certificates (with uncertainty budget) are available as optional add-ons at time of order.
