CZGY WH-962C Rotary Incubator Shaker

Overview

The CZGY WH-962C Rotary Incubator Shaker is a precision-engineered laboratory shaker designed for consistent, low-shear rotational motion in cell culture, microbial growth, suspension-based assays, and biochemical incubation protocols. Unlike orbital or reciprocating shakers, the WH-962C employs true rotary motion—where the platform rotates around a central horizontal axis—generating gentle yet uniform mixing ideal for oxygen-sensitive cultures, low-viscosity media, and fragile suspension cells. Its servo-motor-driven system ensures stable speed control across the full 10–150 rpm range with high reproducibility and minimal mechanical drift. The unit operates on standard single-phase 220 V / 50 Hz power and integrates an LCD interface for intuitive parameter setting, including programmable time intervals up to 9999 minutes (or hours), supporting unattended overnight or multi-day experiments.

Key Features

• Rotary motion architecture optimized for homogeneous suspension and minimized shear stress on biological samples
• LCD digital display with real-time monitoring of speed, elapsed time, and remaining timer duration
• Servo motor control enabling precise speed resolution and rapid acceleration/deceleration response
• Single-platform design with adjustable tilt angle (±0° to ±15°) to modulate mixing intensity and surface-to-volume interaction
• Low-noise operation (<55 dB(A) at 100 rpm), engineered for shared lab environments and noise-sensitive facilities
• Robust aluminum-alloy frame with reinforced platform mounting and anti-slip silicone matting for secure vessel retention
• 250 W motor rated for continuous duty under full load, ensuring thermal stability during extended incubation cycles

Sample Compatibility & Compliance

The WH-962C accommodates up to 120 × 10 mL centrifuge tubes or test tubes per run (standard configuration), with customizable clamping fixtures available upon request—including universal tube holders, microplate adapters, and flask cradles for Erlenmeyer flasks (50–500 mL). All mechanical components comply with IEC 61010-1 safety standards for laboratory electrical equipment. While not certified for ISO Class 5 cleanroom integration, its sealed motor housing and non-particle-shedding materials support use in GLP-compliant laboratories. The device meets basic electromagnetic compatibility (EMC) requirements per EN 61326-1 and is suitable for installation in biosafety cabinets when configured with external ventilation routing.

Software & Data Management

The WH-962C operates as a standalone instrument without proprietary software or PC connectivity. All operational parameters are set and stored locally via the front-panel interface. Timer settings persist through power interruption, and speed calibration is factory-verified using traceable tachometric reference. For laboratories requiring audit-ready records, external data loggers (e.g., USB-connected temperature/humidity/speed sensors compliant with ASTM E2875) may be deployed alongside the unit. Though not natively 21 CFR Part 11 compliant, the device supports manual entry into electronic lab notebooks (ELNs) and aligns with SOP-driven workflows common in QC microbiology and bioprocess development labs.

Applications

• Mammalian and insect cell suspension culture in serum-free or low-serum media
• Bacterial and yeast fermentation studies requiring low-turbulence aeration
• Antibiotic susceptibility testing using broth microdilution formats
• Enzyme kinetics assays where convection-driven mass transfer must remain consistent
• Preparation of homogeneous cell pellets prior to lysis or staining protocols
• Environmental microbiology sampling—e.g., waterborne pathogen enrichment in buffered peptone water
• Pharmaceutical stability testing of liquid formulations under controlled agitation conditions

FAQ

Is the WH-962C suitable for use inside a CO₂ incubator?

No—the unit is not rated for humidified, elevated-CO₂, or temperature-controlled chamber environments. It is intended for ambient-temperature benchtop operation only.
Can the rotation angle be locked at a fixed value?

Yes—the tilt adjustment mechanism includes mechanical detents at 0°, 5°, 10°, and 15°, allowing repeatable angular positioning across experiments.
Does the timer support dual-mode countdown (minutes vs. hours)?

Yes—the LCD interface allows user selection between minute-based and hour-based timing modes prior to start.
What maintenance is required for long-term reliability?

Annual inspection of belt tension (if applicable), cleaning of ventilation grilles, and verification of platform balance using a spirit level are recommended. No routine lubrication is required.
Are replacement platforms or custom fixtures available?

Yes—CZGY offers OEM-compatible accessories including stainless-steel platforms, autoclavable silicone inserts, and application-specific clamps; lead time is typically 2–4 weeks.
