Shanghai Shiping JDX-300 Classic General-Purpose Incubatory Shaker

Overview

The Shanghai Shiping JDX-300 Classic General-Purpose Incubatory Shaker is an engineered platform for reproducible, low-thermal-load agitation of biological samples under ambient laboratory conditions. Designed for consistent orbital or reciprocating motion across a broad operational range (30–300 rpm), it employs a single-axis balanced drive system coupled with NSK double-row precision bearings to minimize mechanical vibration transmission and ensure long-term rotational stability. Unlike temperature-controlled incubator shakers, the JDX-300 operates at ambient conditions—making it ideal for applications where thermal regulation is either externally managed or unnecessary, such as pre-culture mixing, reagent homogenization, or suspension-based cell propagation in climate-stabilized rooms. Its PID-controlled microprocessor continuously monitors motor load and environmental feedback, enabling ±1 rpm speed accuracy and robust resistance to voltage fluctuation or load variance. The unit complies with IEC 61010-1 safety standards for laboratory electrical equipment and integrates dual independent protection circuits—electrical leakage detection and overcurrent cutoff—to meet GLP-aligned lab safety protocols.

Key Features

• Switchable oscillation modes: Orbital (Φ25 mm amplitude) and reciprocating motion, programmable per user-defined protocol
• PID microprocessor control with environmental scanning logic ensures stable speed maintenance across variable flask loads and ambient shifts
• LCD interface with real-time display of setpoint, actual rpm, elapsed time, and remaining timer duration
• Eight-segment programmable curve function supports complex multi-step agitation sequences (e.g., ramp-up → hold → ramp-down)
• Comprehensive safety architecture: Independent audible/visual overspeed alarm, auto-restart after power interruption, parameter retention after shutdown, and non-volatile rpm memory
• Heavy-duty mechanical construction: Quenched-and-tempered 45# carbon steel shaft (220–250 HBW), ductile cast iron base frame, and reinforced cold-rolled steel chassis
• Natural convection airflow design eliminates internal fans—reducing airborne particulate generation and minimizing cross-contamination risk in sterile workflows

Sample Compatibility & Compliance

The JDX-300 accommodates standard microbiological and biochemical vessel configurations on its 550 × 400 mm platform, supporting up to twelve 1000 mL Erlenmeyer flasks, fifteen 500 mL flasks, or twenty-four 250 mL flasks simultaneously. Flask clamping is achieved via universal rubber gasket inserts compatible with glass, PETG, and polycarbonate vessels. All materials in direct contact with the platform—including ABS engineering plastic side panels and powder-coated steel surfaces—meet USP Class VI biocompatibility requirements for non-leaching performance. The device conforms to ISO 13485 manufacturing quality systems and is CE-marked per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). It supports audit-ready documentation for FDA 21 CFR Part 11–aligned environments when paired with validated external data logging systems.

Software & Data Management

While the JDX-300 operates as a standalone instrument with no embedded USB or Ethernet connectivity, its eight-segment programming engine enables full protocol definition without external software. Each segment stores target rpm, dwell time, and direction mode—retained indefinitely in non-volatile memory. For laboratories requiring electronic records, optional RS-232 or analog 0–5 V output modules (sold separately) permit integration with SCADA systems or LIMS platforms compliant with ASTM E2500 and Annex 11 principles. All timer events—including start, pause, end, and fault triggers—are logged locally with timestamp resolution to 0.01 h and can be manually exported via serial dump. Audit trails remain intact through power cycles and firmware resets.

Applications

• Microbial culture expansion in aerobic suspension (E. coli, yeast, bacilli) prior to inoculation into bioreactors
• Suspension-based mammalian cell line passaging in T-flasks or roller bottles under laminar flow hoods
• Antibody-antigen binding kinetics assays requiring gentle, uniform mixing during incubation
• Soil slurry homogenization and aqueous extraction protocols per EPA Method 3550C
• Pre-analytical sample preparation for HPLC, GC-MS, or ELISA workflows where thermal drift must be avoided
• QC/QA batch mixing of calibration standards and reference materials in ISO/IEC 17025-accredited labs

FAQ

Does the JDX-300 include heating or cooling capability?

No. It is an ambient-only shaker; temperature control must be provided externally via room HVAC or secondary incubation chambers.
Can the oscillation mode be changed during operation?

Yes—orbital and reciprocating modes are selectable in real time via front-panel toggle, with immediate mechanical response and no reset required.
Is the platform compatible with magnetic stir bars or vacuum flasks?

The platform lacks integrated magnetic drive; vacuum-rated flasks may be used if mechanically secured—however, negative pressure compatibility is not certified.
What maintenance intervals are recommended for the NSK bearings?

Under continuous 8-hr/day use, NSK bearings require inspection every 12 months; lubrication is factory-sealed and non-serviceable per manufacturer specification.
How is compliance with GLP documented for this instrument?

Factory calibration certificates, material traceability reports, and electrical safety test records are supplied with each unit; IQ/OQ protocols are available upon request for GxP validation support.
