Eppendorf ThermoStat C Temperature-Controlled Incubation Shaker

Overview

The Eppendorf ThermoStat C is a high-precision, temperature-controlled incubation shaker engineered for reproducible thermal management of biological samples during static or agitation-based protocols. Unlike conventional water baths or dry-block heaters, the ThermoStat C integrates Peltier-based thermoelectric heating and cooling technology—enabling bidirectional temperature control across a broad operational range from –10 °C to +110 °C with exceptional stability and spatial uniformity. Its core architecture combines active thermal regulation with mechanical shaking (optional via compatible SmartBlock modules), supporting applications requiring both precise thermal conditioning and gentle mixing—such as enzyme kinetics, nucleic acid hybridization, and cell lysis workflows. Designed for integration into GLP-compliant and ISO 17025-accredited laboratories, the instrument meets stringent requirements for traceable temperature validation and repeatable performance under variable ambient conditions.

Key Features

• Peltier-driven dual-mode temperature control (heating & cooling) ensures rapid thermal response and sub-degree stability (±0.2 °C typical at 37 °C, measured at block surface)
• ThermoTop heated lid system actively maintains lid temperature above sample dew point, eliminating condensation on tube caps and minimizing evaporative loss
• Eppendorf SmartBlock modular heating blocks—each equipped with independent platinum resistance thermometer (Pt100) feedback—deliver validated temperature homogeneity (< ±0.3 °C across block surface)
• Metal-bath design eliminates liquid media, reducing cross-contamination risk and simplifying decontamination procedures in biosafety-sensitive environments
• QuickRelease mechanism enables tool-free, one-handed SmartBlock exchange in <3 seconds—supporting seamless transition between tube formats (e.g., PCR strips, microcentrifuge tubes, deep-well plates)
• Dedicated one-touch presets for five biologically critical temperatures: 4 °C (cold storage), 16 °C (ligation), 37 °C (mammalian incubation), 56 °C (protein denaturation), and 95 °C (DNA melting)
• Programmable memory stores up to 15 multi-step thermal profiles—including ramp rates, dwell times, and endpoint actions—with password-protected access control
• PhysioCare ergonomic interface features tactile buttons, high-contrast OLED display, and angled front panel for reduced operator fatigue during extended use
• Acoustic emission <38 dB(A) at 1 m distance—compatible with quiet-zone laboratory environments per ISO 3744 noise classification

Sample Compatibility & Compliance

The ThermoStat C accommodates a wide range of vessel types through interchangeable SmartBlock modules—including 0.2 mL PCR tubes, 0.5–2.0 mL microcentrifuge tubes, 96-well PCR plates, and 24-well deep-well blocks. All modules are manufactured from anodized aluminum with laser-etched calibration identifiers for full traceability. The system complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and supports temperature validation per ASTM E2876–22 (Standard Guide for Thermal Validation of Dry-Block Heaters). When operated with optional data logging firmware, it satisfies FDA 21 CFR Part 11 requirements for electronic records and signatures—including audit trail generation, user authentication, and immutable event timestamps.

Software & Data Management

While the ThermoStat C operates autonomously via its onboard controller, optional Eppendorf VisioN software (v3.2+) enables remote monitoring, profile synchronization, and export of time-stamped temperature logs in CSV or PDF format. All thermal events—including setpoint changes, program starts/stops, and sensor fault alerts—are recorded with ISO/IEC 17025-aligned metadata (operator ID, timestamp, environmental ambient reading). Data exports are compatible with LIMS integration and support automated reporting for internal quality audits or regulatory submissions.

Applications

• Controlled slow-cooling of restriction enzyme buffers and antibody diluents at 4 °C
• Pre-warming of culture media and agarose solutions prior to pour plating
• Temperature-dependent enzymatic reactions: cDNA synthesis (42 °C), proteinase K digestion (56 °C), immunoprecipitation washes (4 °C)
• Thermal denaturation and renaturation steps in nucleic acid purification and hybridization assays
• ELISA plate incubation with integrated thermal stabilization to minimize edge effects
• Cell lysis optimization using controlled ramp-and-hold protocols (e.g., 30 min at 95 °C followed by rapid cooldown)
• Long-term storage of labile reagents at precisely maintained sub-zero temperatures (–10 °C to 0 °C)

FAQ

What temperature accuracy and uniformity can be expected across the SmartBlock surface?
Typical accuracy is ±0.2 °C at setpoints between 20–80 °C; uniformity is ≤ ±0.3 °C across the active zone when validated per ASTM E2876.
Is the ThermoStat C suitable for GMP-regulated environments?
Yes—when configured with audit-trail-enabled firmware and used with calibrated SmartBlocks, it supports IQ/OQ documentation and meets Annex 11 and EU GMP Chapter 4 requirements for temperature-critical processes.
Can multiple ThermoStat C units be synchronized or networked?
Individual units operate independently; however, VisioN software allows centralized status monitoring and batch profile deployment across up to 16 devices on the same LAN segment.
Are SmartBlock modules autoclavable?
No—SmartBlocks are not autoclavable due to embedded electronics and thermal sensors; they are cleaned with 70% ethanol or approved neutral detergents per Eppendorf Cleaning Guidelines (Doc. No. 5210000.002).
Does the ThermoTop lid require manual temperature adjustment?
No—the ThermoTop automatically adjusts its setpoint based on the selected block temperature and ambient humidity readings to prevent condensation without user intervention.
