JEIO TECH CMS-350 Compact Orbital Shaker

Overview

The JEIO TECH CMS-350 Compact Orbital Shaker is an engineered solution for precise, low-shear orbital agitation in space-constrained laboratory environments. Designed around a robust brushless DC motor and PID-controlled feedback loop, it delivers stable, repeatable motion across its full speed range (50–300 rpm) with ±5 rpm accuracy at 100 rpm—critical for applications demanding mechanical consistency without thermal perturbation. Unlike heated or refrigerated shakers, the CMS-350 operates at ambient temperature only, making it ideal for integration into incubators, cold rooms, environmental chambers, and biosafety cabinets where external thermal load or condensation must be avoided. Its compact footprint (249 × 325 × 109 mm) and lightweight construction (8 kg net weight) enable seamless deployment in multi-tiered equipment stacks or confined benchtop workflows. The unit employs a circular orbital motion pattern with a fixed 13 mm diameter orbit—optimized for uniform suspension of cells, antibodies, beads, and reagents in hybridization, immunostaining, blotting, and enzymatic assays.

Key Features

• Brushless DC motor: Ensures maintenance-free operation, silent performance (<55 dB(A)), consistent torque delivery, and extended service life under continuous duty cycles.
• PID-based speed control: Provides real-time feedback regulation for stable rotational output—even during load variations or voltage fluctuations (AC 100–240 V, 50/60 Hz).
• Vacuum fluorescent display (VFD): High-contrast, color-enhanced interface with intuitive touch-sensitive keys for rapid parameter entry and visual confirmation.
• Programmable timer: Adjustable from 1 minute to 99 hours and 59 minutes; supports automatic shutdown and memory retention after power interruption.
• Chemically resistant housing: Polypropylene (PP) chassis offers excellent resistance to common lab solvents, acids, and bases—facilitating wipe-down decontamination and long-term durability.
• Integrated safety systems: Overcurrent protection, self-diagnostic error detection, and automatic fault flagging (e.g., motor stall, sensor failure, or timer timeout).

Sample Compatibility & Compliance

The CMS-350 accommodates diverse sample formats via interchangeable accessories mounted on its universal 250 × 250 mm platform. Compatible configurations include microplate clamps (up to six 96-well plates), stainless-steel or polymer conical flask holders (for volumes from 50 mL to 6 L), separatory funnel fixtures, tube racks (supporting diameters from 8 mm to 50 mm), and custom silicone or rubber matting for irregular vessels. All accessories are mechanically secured without tools and maintain positional integrity at maximum rated speed. While the CMS-350 itself does not incorporate active temperature control, its ambient-only operation aligns with ISO 15197:2013 and CLSI EP15-A3 guidelines for non-thermal instrumentation used in diagnostic assay preparation. When deployed within validated environmental enclosures (e.g., CO₂ incubators meeting ISO 13485 requirements), the system supports GLP-compliant workflows requiring audit-trail-capable timing logs—especially when paired with optional data export modules.

Software & Data Management

The CMS-350 operates as a standalone instrument with no embedded software stack or network connectivity. All operational parameters—including setpoint speed, elapsed time, remaining duration, and error codes—are displayed locally on the VFD and retained in volatile memory during brief power loss. For laboratories requiring electronic recordkeeping per FDA 21 CFR Part 11, third-party data loggers may be interfaced via analog tachometer output (0–5 V DC proportional to rpm) or digital pulse signals. JEIO TECH provides calibration certificates traceable to NIST standards upon request, supporting IQ/OQ documentation for regulated environments. Firmware updates are not applicable; hardware-level stability ensures long-term configuration consistency across instrument lifecycles.

Applications

• Molecular biology: DNA/RNA hybridization, Southern/Northern blotting, probe incubation, and library normalization steps.
• Immunology & histopathology: Antibody binding, antigen retrieval, IHC/IF staining, and chromogenic development.
• Cell culture: Gentle resuspension of adherent cells post-trypsinization, co-culture mixing, and bioreactor seed train preparation.
• Protein biochemistry: ELISA plate washing, affinity chromatography equilibration, and ligand-binding kinetics assays.
• Quality control: Stability testing of reagents, buffer exchange validation, and particulate dispersion verification in pharmaceutical excipients.

FAQ

Does the CMS-350 include heating or cooling capability?
No. It is an ambient-only orbital shaker with no integrated temperature regulation. It is intended for use inside externally controlled environments such as incubators or cold rooms.
What is the maximum load capacity of the platform?
The platform supports up to 5.2 kg (11.46 lbs) evenly distributed across its surface area.
Can the CMS-350 be used inside a CO₂ incubator?
Yes—its compact dimensions, PP housing, and lack of heat-generating components make it suitable for placement inside standard CO₂ incubators, provided airflow and humidity levels remain within manufacturer-specified limits.
Are accessories included with the base unit?
No. All platforms, clamps, racks, and mats are optional accessories ordered separately using JEIO TECH part numbers (e.g., AAA23550 for 50 mL flask holders).
Is the CMS-350 compliant with electromagnetic compatibility (EMC) standards?
Yes—it meets IEC 61326-1:2013 for laboratory equipment regarding emission and immunity, certified for CE marking in the European Economic Area.
