Esco ES-80 Programmable Orbital Shaking Incubator

Overview

The Esco ES-80 Programmable Orbital Shaking Incubator integrates precise temperature regulation with controlled orbital agitation in a single compact platform—engineered for reproducible cultivation and mixing of biological samples under physiologically relevant conditions. Based on forced-air convection heated by PID-regulated resistive elements and monitored via high-stability NTC sensors, the unit maintains uniform thermal distribution across the chamber interior (±0.3 °C at 37 °C, typical). Its orbital shaking mechanism employs direct-drive brushless DC motor technology with soft-start and deceleration profiles, minimizing mechanical stress on cultures during acceleration and braking phases. This architecture ensures long-term operational stability and eliminates belt-driven wear or slippage—a critical reliability factor for unattended overnight or multi-day experiments. Designed for ISO 13485-aligned laboratories and compliant with IEC 61010-1 safety standards, the ES-80 supports GLP/GMP workflows through traceable parameter logging and user-accessible calibration offsets.

Key Features

• Microprocessor-controlled PID temperature regulation with 0.1 °C setting resolution and ambient +5 to 80 °C operational range
• Orbital agitation at 50–250 rpm with fixed 20 mm orbit diameter; programmable ramping and dwell functions
• Dual-line LCD interface displaying real-time temperature, speed, elapsed time, and remaining timer duration
• Insulated chamber constructed with high-efficiency polyurethane foam (≥40 mm thickness) and double-glazed tempered glass door for thermal retention
• Interchangeable platforms—including universal non-slip PP-400 and flask-specific clamping variants (P30-100, P16-250, P9-500, P6-1000)—supporting vessels from 30 mL test tubes to 1 L Erlenmeyer flasks
• Programmable timer (1 minute to 96 hours) with auto-restart and hold modes; continuous operation capability up to 168 hours
• Integrated safety systems: overtemperature cut-off, motor stall detection, and door-open alarm with automatic agitation suspension

Sample Compatibility & Compliance

The ES-80 accommodates standard laboratory containers used in microbial growth, suspension cell culture, protein expression, and biochemical processing—including baffled flasks, deep-well plates, and roller bottles. Its internal height of 270 mm allows vertical clearance for stacked vessel configurations without impeding airflow. The unit meets EN 61000-6-3 (EMC emission) and EN 61000-6-2 (immunity) requirements and is CE-marked per the EU Machinery Directive 2006/42/EC. For regulated environments, its parameter lockout function prevents unauthorized modifications, and all setpoints are retained after power interruption. While not inherently 21 CFR Part 11 compliant, audit-ready data export (via optional RS-232/USB interface module) enables integration into validated electronic lab notebook (ELN) or LIMS systems supporting ALCOA+ data integrity principles.

Software & Data Management

The ES-80 operates autonomously via front-panel controls; no external software is required for basic operation. Optional connectivity modules enable serial data streaming (ASCII format) of real-time temperature, speed, and timer status to host PCs for trend analysis or centralized monitoring. Logged parameters can be timestamped and exported for inclusion in experimental records, supporting traceability requirements under ISO/IEC 17025 and FDA guidance for laboratory data handling. Firmware updates are performed locally using USB flash drives, with version history and checksum verification ensuring integrity.

Applications

• Mammalian, insect, and plant cell suspension cultures requiring simultaneous temperature control and gentle agitation
• Bacterial growth kinetics studies (e.g., E. coli expression strains) across physiological to elevated temperatures (up to 80 °C)
• Enzyme assays, antigen-antibody hybridization, and nucleic acid extraction protocols demanding consistent mixing
• Gel staining/destaining, plasmid purification, and protein solubilization workflows where thermal homogeneity reduces batch variability
• Long-term incubation experiments (≥7 days) in microbiology and synthetic biology labs with uninterrupted thermal and mechanical stability

FAQ

What is the minimum operating temperature relative to ambient?

The ES-80 maintains stable control down to ambient +5 °C; it does not provide active cooling.

Can the unit be validated for GxP environments?

Yes—its temperature uniformity, stability, and programmability support IQ/OQ protocols; users must perform site-specific PQ with calibrated reference probes.

Is the shaking motion truly orbital, or is it reciprocating?

It generates true circular orbital motion with a 20 mm diameter path, optimized for oxygen transfer in liquid cultures without vortex formation.

How is temperature uniformity verified inside the chamber?

Esco specifies ±0.3 °C deviation at three defined points (center, front-left, rear-right) at 37 °C per internal validation SOP; users may replicate this using Class A PT100 probes.

Are platform accessories included by default?

No—the base configuration includes only the standard non-clamping platform; all flask-specific fixtures are optional and ordered separately.
