ES-20 Benchtop Programmable Orbital Shaking Incubator

Overview

The ES-20 Benchtop Programmable Orbital Shaking Incubator is an integrated life science instrument engineered for simultaneous temperature-controlled incubation and orbital shaking of biological and biochemical samples. Designed around a precision microprocessor-based control architecture, it employs forced-air convection with PID-regulated heating and direct-drive orbital motion to maintain stable thermal environments while delivering reproducible mixing performance. Its orbital agitation mechanism—characterized by a 10 mm diameter circular path—ensures uniform suspension of microbial cultures, cell suspensions, enzyme assays, and recombinant expression systems without shear-induced damage typical of reciprocating or eccentric shakers. The unit operates within a defined physiological temperature range (25–42 °C), with active control extending down to ambient +5 °C, making it suitable for mesophilic bacterial growth, yeast fermentation, mammalian cell expansion, and protein solubilization protocols requiring gentle yet consistent agitation.

Key Features

• Microprocessor-controlled temperature regulation with forced-air circulation ensures ±0.3 °C uniformity across the chamber interior (measured at 37 °C, no load)
• Direct-drive orbital shaker mechanism eliminates belt wear and backlash, supporting long-term operational stability and low-maintenance operation
• Programmable timer with 1-minute to 96-hour range enables unattended overnight or multi-day incubation-shaking cycles
• High-resolution dual-parameter display (2-line × 16-character LCD) shows real-time setpoints and actual values for temperature, speed, and remaining time
• Modular platform system with four interchangeable options (P12-100, P6-250, PP-4, PUP-12) accommodates diverse vessel geometries—from Petri dishes and Erlenmeyer flasks to culture tubes and beakers
• Structural housing constructed from reinforced ABS with a 7 mm thick transparent acrylic front panel for continuous visual monitoring without compromising thermal integrity
• Compact footprint (340 × 340 × 435 mm) and lightweight design (15 kg) facilitate placement in biosafety cabinets, cold rooms, or shared core facility benchtops

Sample Compatibility & Compliance

The ES-20 supports standard laboratory vessels including glass and polycarbonate Erlenmeyer flasks (up to 500 mL equivalent loading), cylindrical culture bottles, multi-well plates (when secured on PP-4 platform), and sterile Petri dishes. All platforms are autoclavable (121 °C, 20 min) except PUP-12’s adjustable rods (which require ethanol wipe disinfection). The instrument complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets EN 60335-1 requirements for heated appliances. While not certified for ISO Class 5 cleanroom use, its sealed chamber design minimizes particulate ingress and supports GLP-compliant documentation when paired with external audit-trail-capable data loggers.

Software & Data Management

The ES-20 operates as a standalone hardware-controlled system with no embedded software stack or network interface. All parameters are configured via front-panel keypad navigation; settings are retained through power cycling. For traceability in regulated environments (e.g., ISO 17025-accredited labs or FDA-regulated QC workflows), users may integrate external USB or RS-232 data loggers compliant with 21 CFR Part 11 requirements. Optional third-party LabVIEW or Python-based acquisition scripts can poll real-time status via TTL-level serial output (available upon request with adapter cable), enabling synchronization with spectrophotometers or pH meters in multi-instrument assay workflows.

Applications

• Microbial growth kinetics studies under controlled aeration and temperature
• Recombinant protein expression in E. coli and yeast using autoinduction media
• Enzymatic reaction optimization requiring homogeneous substrate dispersion
• Cell line passaging and suspension culture maintenance prior to transfection or cryopreservation
• Biochemical oxygen demand (BOD) sample agitation per ASTM D5210-19 guidelines
• Antibiotic susceptibility testing with broth microdilution formats
• Extraction efficiency validation for metabolite recovery from solid-phase matrices

FAQ

Is the ES-20 suitable for CO₂-sensitive applications?

No — this unit lacks CO₂ supplementation or pH buffering capability; it is strictly a temperature- and agitation-controlled incubator.
Can the ES-20 be operated inside a refrigerated room?

Yes, provided ambient temperature remains ≥15 °C and relative humidity stays below 80% non-condensing to prevent condensation on internal electronics.
What is the calibration interval recommendation?

Annual verification against NIST-traceable thermistors and tachometers is advised; internal sensor drift is typically <±0.2 °C and <±2 rpm over 12 months under normal use.
Are replacement platforms available separately?

Yes — all four platform types (P12-100, P6-250, PP-4, PUP-12) are stocked and sold individually with full dimensional and material certifications.
Does the unit include a security lock or user access control?

No — parameter changes are accessible to any operator via the front panel; physical access restriction must be implemented externally.
