Overview
The ES-20 Programmable Orbital Incubator Shaker is an engineered platform for controlled, temperature-regulated orbital agitation in microbiological, cell culture, and molecular biology applications. Designed around a precision-engineered eccentric drive mechanism, it delivers consistent 10 mm orbital motion—optimized to minimize shear stress while ensuring homogeneous suspension and gas exchange in aerobic cultures. Integrated Peltier-based heating and intelligent PID temperature control maintain chamber uniformity within ±0.3 °C across the full 25–42 °C operating range, with resolution of 0.1 °C. Unlike ambient shakers, the ES-20’s fully enclosed incubation chamber eliminates evaporative loss and enables stable, reproducible growth conditions over extended durations (up to 96 hours), supporting protocols aligned with ISO 13485-compliant bioprocess development and GLP-aligned microbial viability studies.
Key Features
- Programmable dual-parameter control: independent real-time adjustment of speed (50–250 rpm) and temperature (25–42 °C) via intuitive 2-line LCD interface
- Orbital motion with 10 mm diameter trajectory—validated for low-shear suspension of sensitive eukaryotic cells and recombinant bacterial strains
- Robust aluminum alloy chassis with insulated double-wall chamber, minimizing thermal drift and external heat radiation
- Over-temperature and motor stall protection circuits compliant with IEC 61010-1 safety standards
- Universal mounting system supporting rapid interchange of four standardized platforms without tools
- Energy-efficient operation: <120 W typical power draw during simultaneous heating and shaking at mid-range settings
Sample Compatibility & Compliance
The ES-20 accommodates diverse vessel formats via interchangeable platforms: P12-1000 (12×100/150 mL Erlenmeyer flasks), PP-4 (219×219 mm anti-slip rubber mat for T-flasks and Petri dishes), P6-250 (6×250/400 mL flasks), and PUP-12 (270×195 mm universal plate with adjustable dividers for tubes, microplates, or irregular containers). All platforms are autoclavable (121 °C, 20 min) and chemically resistant to common sterilants (e.g., 70% ethanol, 0.5% sodium hypochlorite). The unit meets CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and its temperature stability profile supports compliance with USP for cell culture equipment qualification and ASTM E2500-13 Annex A3 for laboratory instrument verification.
Software & Data Management
While the ES-20 operates as a standalone benchtop instrument with embedded firmware, its parameter setpoints and runtime logs (start time, duration, final temperature/speed) are retained in non-volatile memory across power cycles—enabling traceability for audit-ready workflows. For laboratories requiring electronic record integration, optional RS-232 serial output (with TTL-level adapter) permits connection to LIMS or custom SCADA systems. All stored parameters comply with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate), and timestamped session data satisfies FDA 21 CFR Part 11 requirements when paired with validated third-party data acquisition software featuring user authentication and audit trail generation.
Applications
- Escherichia coli and Bacillus subtilis high-yield fermentation in LB or TB media
- Adherent and suspension mammalian cell expansion (CHO, HEK293) under controlled O2/CO2-equilibrated conditions
- Enzyme kinetics assays requiring precise thermal and mixing consistency
- Antibiotic susceptibility testing (AST) per CLSI M07-A11 guidelines
- Yeast two-hybrid library screening with multi-well plate compatibility on PP-4 platform
- Pre-incubation of PCR master mixes and restriction digests to ensure reagent homogeneity
FAQ
Is the ES-20 suitable for CO2-controlled environments?
No—the ES-20 provides heated orbital agitation only; it lacks CO2 regulation or humidity control. For CO2-dependent cultures, integrate with an external CO2 incubator or select a dedicated CO2 shaker model.
Can the unit be operated continuously for >96 hours?
Yes—while the built-in timer caps at 96 h, manual restart or external relay control enables unattended multi-day runs. Thermal management remains stable under continuous duty cycle.
What calibration documentation is supplied?
Each unit ships with a factory-verified temperature and speed calibration certificate traceable to UKAS-accredited standards (NPL reference), valid for 12 months from date of dispatch.
Are platform accessories covered under warranty?
All listed platforms (P12-1000, PP-4, P6-250, PUP-12) carry the same 24-month limited warranty as the base unit, excluding consumables and damage from improper sterilization.
Does the ES-20 meet GMP requirements for QC labs?
Yes—its design supports IQ/OQ execution per ASTM E2500-13, and its parameter retention, alarm logging, and physical access controls align with Annex 11 and EU GMP Chapter 4 expectations for ancillary lab equipment.
