KS-12 Immersion-Type Horizontal Oscillator

Overview

The KS-12 Immersion-Type Horizontal Oscillator is an engineered benchtop shaker designed for reproducible, low-shear horizontal reciprocating motion in aqueous and semi-aqueous sample environments. Unlike orbital or rotary shakers, this unit employs a linear back-and-forth oscillation mechanism—ideal for leaching studies, solid–liquid extraction, suspension homogenization, and microbial culture under non-aerated or minimally agitated conditions. Its immersion-capable design allows direct placement of sample containers (e.g., wide-mouth glass or HDPE bottles) into water baths or temperature-stabilized liquid media without platform modification. The oscillator operates at ambient temperature only and is not equipped with integrated heating or cooling; thermal control must be externally maintained via bath circulation or environmental chamber. Built for continuous-duty laboratory use, the KS-12 delivers stable speed output across its full 60–300 rpm range through microprocessor-based closed-loop motor control with real-time power compensation—ensuring consistent torque and minimal speed drift under variable load.

Key Features

• Microcontroller-driven reciprocating drive system with digital speed regulation and automatic power compensation to maintain constant oscillation frequency regardless of load inertia or voltage fluctuation.
• Precision-timed operation with programmable digital timer (0–9999 minutes), supporting both discrete timed runs and indefinite continuous mode (0 h 0 min setting).
• Robust single-platform architecture featuring a 40 mm stroke amplitude optimized for efficient mixing of viscous suspensions, soil leachates, biological slurries, and culture media without foaming or splashing.
• Low-noise, brushless AC motor rated for ≥8 hours of uninterrupted operation per cycle; power consumption: 60 W nominal.
• Ergonomic front-panel interface with intuitive up/down speed adjustment keys, dedicated hour/minute time-setting buttons, RUN/STOP actuation, and dual-color status LEDs (green = active, red = standby/stopped).
• Structural stability enhanced by heavy-gauge steel frame and reinforced mounting base—recommended for anchoring on concrete floors when operating above 200 rpm to mitigate displacement from inertial forces.

Sample Compatibility & Compliance

The KS-12 accommodates up to twelve 2 L wide-mouth bottles (e.g., ASTM D3987-compliant leaching vessels) simultaneously on its single oscillating plate. It supports standard laboratory containers including polypropylene centrifuge bottles, borosilicate glass jars, and stainless-steel extraction vessels—provided they are securely clamped using optional universal bottle holders (not included). While the unit itself does not incorporate temperature regulation, its open-platform configuration permits integration into ISO/IEC 17025-accredited leaching workflows where external bath temperature is monitored and logged per EPA Method 1311 or TCLP protocols. Electrical safety complies with IEC 61010-1 for laboratory equipment; grounding via three-pin socket is mandatory. No internal electronics are exposed to moisture—fluid ingress into housing voids is strictly prohibited per manufacturer guidelines to prevent corrosion of PCBs and motor windings.

Software & Data Management

The KS-12 operates as a standalone hardware device with no embedded firmware update capability or PC connectivity. All operational parameters—including setpoint speed, elapsed time, and run status—are displayed locally via dual seven-segment LED indicators. No data logging, USB export, or audit trail functionality is provided. For GLP/GMP-aligned laboratories, users must implement external documentation practices: manual recording of start/stop times, speed settings, and batch identifiers in bound logbooks or validated electronic lab notebooks (ELNs). Where regulatory compliance requires traceability (e.g., FDA 21 CFR Part 11), integration with third-party environmental monitoring systems (via relay-triggered I/O modules) may be implemented at the facility level—but such configurations fall outside the scope of factory-supplied functionality.

Applications

• Environmental leaching tests (e.g., TCLP, SPLP, ASTM D5233) for heavy metal and organic contaminant release from soils, sediments, and industrial waste matrices.
• Homogenization of clinical specimens (urine, stool suspensions, tissue homogenates) prior to microbiological analysis or immunoassay preparation.
• Extraction of bioactive compounds from plant biomass, algae, or fungal mycelia under controlled agitation without emulsification.
• Preparation of calibration standards and reference materials requiring uniform particle dispersion in aqueous carriers.
• Maintenance of low-oxygen bacterial cultures (e.g., Clostridium, Bacteroides) where vigorous aeration would inhibit growth.
• Quality control mixing in food safety labs for pathogen enrichment broths (e.g., BPW, TSB) per ISO 6579 and AOAC guidelines.

FAQ

Does the KS-12 support temperature control?
No. The unit operates at ambient temperature only and lacks integrated heating or cooling elements. External temperature management must be achieved via water bath immersion or climate-controlled room environments.
Can the KS-12 be used inside a CO₂ incubator?
Not recommended. The device is not rated for high-humidity or elevated-CO₂ atmospheres. Condensation and gas exposure may compromise electrical insulation and motor longevity.
What is the maximum safe operating speed on non-anchored surfaces?
For stable operation without floor anchoring, speeds ≤200 rpm are advised. Above this threshold, inertial displacement increases significantly—especially when loaded with 12 × 2 L bottles.
Is the timer battery-backed?
No. Timer memory resets upon power interruption. Users must re-enter settings after each power cycle.
Are replacement platforms or custom夹具 available from the manufacturer?
CZGY offers optional universal bottle clamps and reinforced aluminum platforms as accessories. Custom fixture designs require OEM consultation and are subject to minimum order quantities.
