Jeio Tech IST Series Orbital Shaking Incubator

Overview

The Jeio Tech IST Series Orbital Shaking Incubator is an integrated benchtop platform engineered for precise, reproducible cultivation of microbial, mammalian, and suspension cell cultures under controlled thermal and mechanical conditions. Combining microprocessor-driven PID temperature regulation with high-fidelity orbital shaking—characterized by a consistent 19.1 mm circular orbit diameter—the system supports aerobic growth kinetics, enzyme assays, solubility studies, and biochemical reaction optimization. Unlike static incubators, the IST series delivers uniform oxygen transfer and suspension homogeneity across flask, tube, and multi-well plate formats. Its dual-mode capability—standard heating-only (IST-3075/4075) and refrigerated heating-cooling (IST-3075R/4075R)—enables operation from as low as 15°C up to 80°C, accommodating both mesophilic and thermophilic applications. All models conform to DIN 12880 for laboratory incubators, ensuring traceable performance validation under defined ambient conditions (15–40°C).

Key Features

• Intuitive 4.3-inch capacitive touchscreen LCD interface with icon-based navigation and multilingual menu support (English, Korean, Chinese, Spanish).
• Auto-recovery function retains setpoints and operational status after power interruption; resumes scheduled protocols without manual reconfiguration.
• Brushless DC motor drive ensures silent, vibration-free operation with exceptional speed stability—even under variable load conditions—and eliminates brush wear, extending service life beyond 20,000 hours.
• Dynamic speed compensation algorithm continuously monitors platform inertia and adjusts motor torque in real time to maintain nominal RPM when surface-level imbalances occur (e.g., uneven benchtops or asymmetric vessel loading).
• Integrated over-current protection halts shaking immediately upon detection of abnormal current draw, preventing motor damage and enabling safe platform inspection.
• Three-speed adjustable internal fan accelerates temperature recovery (<6 min to re-stabilize after 30-second door opening at 37°C) while minimizing thermal stratification.
• Triple-point temperature calibration routine allows user-accessible offset adjustment at three reference points (25°C, 37°C, 60°C), supporting ISO/IEC 17025-compliant instrument qualification.
• Hermetic silicone gasket seal and pressure-balanced acrylic lid with gas-assisted lift mechanism ensure minimal heat loss and unobstructed visual monitoring without compromising chamber integrity.

Sample Compatibility & Compliance

The IST series accommodates standard culture vessels including Erlenmeyer flasks (up to 5 L), test tubes, deep-well plates, and roller bottles. The rigid stainless-steel interior (AISI 304) resists corrosion from repeated exposure to ethanol, isopropanol, and mild alkaline cleaning agents—critical for GLP/GMP environments requiring validated decontamination cycles. Refrigerated models utilize R134a refrigerant (zero ozone depletion potential), compliant with EU F-Gas Regulation (EU No. 517/2014). All units are CE-marked and meet IEC 61010-1 safety standards for laboratory equipment. Temperature uniformity (±0.1°C at 37°C) and stability (±0.5°C variation over 24 h) are verified per DIN 12880 Annex B, with optional IQ/OQ documentation packages available for FDA-regulated labs.

Software & Data Management

Built-in RS-232 and USB-B ports enable direct connection to PCs for remote control and real-time data logging via Jeio Tech’s proprietary IST Control Software (Windows-compatible). The software records timestamped temperature, speed, and timer values at user-defined intervals (1 s to 60 min), exports CSV files compatible with LIMS integration, and generates audit-trail logs meeting 21 CFR Part 11 requirements—including electronic signatures, operator ID tagging, and immutable event history. Optional Ethernet module (IST-NET) adds TCP/IP connectivity for centralized lab-wide monitoring through enterprise SCADA platforms.

Applications

• Microbial growth profiling (E. coli, yeast, Bacillus spp.) under varying aeration and thermal stress conditions.
• Protein expression optimization in shake flasks using auto-induction media.
• Cell line expansion for bioprocess development, including CHO and HEK293 suspension cultures.
• Enzyme kinetic assays requiring strict temperature control during continuous agitation.
• Solubility and dissolution testing of APIs in pharmaceutical formulation development.
• Environmental microbiology studies involving soil slurry enrichment or wastewater biofilm dispersion.

FAQ

What is the maximum recommended load capacity for stable operation at 500 rpm?
For IST-3075/3075R models, the rated load is 10 kg at 500 rpm; for IST-4075/4075R, it is 18 kg at 400 rpm. Exceeding these limits may trigger automatic shutdown due to over-current detection.
Does the unit support validation documentation for regulated laboratories?
Yes—factory-installed temperature sensors are NIST-traceable, and optional IQ/OQ kits include protocol templates, calibration certificates, and performance verification reports aligned with ASTM E2500 and EU Annex 15 guidelines.
Can the incubator operate continuously for extended periods (e.g., 7+ days)?
Yes—designed for unattended 24/7 operation with redundant thermal cutoffs (mechanical and electronic), fan-failure detection, and non-volatile memory retention for all operational parameters.
Is humidity control available as an add-on feature?
No—humidity is not regulated in the IST series. For humidified applications, Jeio Tech recommends the HST series CO₂ incubators with integrated steam generators.
How often does the system require preventive maintenance?
Annual verification of temperature calibration and mechanical alignment is advised; brushless motor design eliminates routine commutator servicing, reducing lifecycle maintenance costs by >40% versus brushed alternatives.
