Structure and operation specifications of ultra-clean workbench

The ultra-clean workbench is a specialized purification system that utilizes air filtration technology to create a dust-free and sterile environment within a specific operational area. It consists of three main components: an air filter unit, an ultraviolet sterilizer, and a control console. This equipment is widely used in laboratories, pharmaceuticals, and other fields where maintaining a clean and controlled atmosphere is crucial. **Features:** 1. The workbench can switch between horizontal and vertical airflow modes depending on the process requirements. 2. It features an adjustable fan system with a touch-sensitive switch and stepless voltage control, ensuring consistent and optimal airflow speed in the working area. **Technical Parameters:** | Model | SW-CJ-1FB | SW-CJ-2FB | |--------------|-------------------|-------------------| | Cleanliness | Level 100 @≥0.5μm (US Federal 209E) | Level 100 @≥0.5μm (US Federal 209E) | | Colony Count | <0.5 pcs/dish (90mm culture plate) | <0.5 pcs/dish (90mm culture plate) | | Noise | ≤62dB(A) | ≤62dB(A) | | Average Wind Speed | 0.25–0.45 m/s | 0.25–0.45 m/s | | Vibration | ≤0.5μm (X·Y·Z) | ≤0.5μm (X·Y·Z) | | Illuminance | ≥300LX | ≥300LX | | Power Supply | AC, single phase 220V/50HZ | AC, single phase 220V/50HZ | | Power Consumption | 330W | 400W | | Weight | 150KG | 300KG | | Working Size | 870×500×620mm | 1360×500×620mm | | Dimensions | 1050×760×1800mm | 1600×760×1800mm | | HEPA Filter | 865×600×38×1 | 865×484×38×1 | | Fluorescent / UV Lamp | 20W×1 / 20W×1 | 30W×1 / 30W×1 | **Working Principle:** The air is drawn into the pre-filter through a fan, then passed through a high-efficiency filter inside a static pressure box before being released as either vertical or horizontal airflow. This ensures the working area reaches a 100-level cleanliness standard, meeting strict environmental requirements. Ultra-clean workbenches are categorized based on airflow direction (vertical or horizontal), operation structure (unilateral or bilateral), and application (general, biological, or medical). **Operating Procedures:** 1. Check the operating environment, including temperature, air quality, and power supply, and record usage information. 2. Place all necessary equipment and sterilized materials on the workbench surface, arranging them on the left and right sides respectively. 3. Lower the glass shield and turn on the UV lamp for 30 minutes to disinfect the surface. 4. After 30 minutes, turn off the UV lamp, start the fan, adjust the airflow, and turn on the light. 5. Raise the glass shield to about 20 cm, wipe your hands and the workbench with 75% alcohol, and perform the operation smoothly. 6. Light the alcohol lamp and strictly follow aseptic procedures during the experiment. 7. After finishing, remove the equipment from the workbench, clean the surface with 75% alcohol, and turn off the lights, fan, and shield. 8. Turn off the UV lamp after it has been on for 15 minutes. **Precautions:** 1. Do not store items in the workbench for extended periods. 2. Avoid direct exposure to UV light, as it can be harmful to the skin and eyes. Single-layer glass can block UV rays effectively. 3. Always follow aseptic operation protocols during the process. 4. Avoid frequent switching of UV lamps and lighting tubes to extend their lifespan. 5. Regularly check and replace air filters when they become aged. This ultra-clean workbench is essential for maintaining a sterile and controlled environment in various scientific and industrial applications. Its advanced filtration and airflow systems make it a reliable tool for researchers and professionals who require precision and cleanliness in their work.

Stereo Amplifiers

Designed for discerning audiophiles and modern lifestyle enthusiasts, an integrated stereo amplifier seamlessly combines power amplification, pre-amplification, and signal switching into a single compact unit, delivering rich, balanced sound for music, movies, and gaming. Ideal for home entertainment systems, hi-fi setups, and minimalist living spaces, this all-in-one solution eliminates clutter while optimizing performance.

Key Features & Advantages

  1. Pure Stereo Performance
    • Delivers clean, distortion-free audio with Class AB or Class D amplification (typically 50–200W per channel into 8Ω), ensuring dynamic range and tonal accuracy for genres from classical to rock.
    • High-quality components like audiophile-grade capacitors and toroidal transformers reduce noise and enhance clarity.
  2. Versatile Connectivity
    • Analog Inputs: RCA, 3.5mm aux, and phono (for turntables), catering to vintage and modern sources.
    • Digital Inputs: Optical (TOSLINK), coaxial, or Bluetooth 5.3 (aptX HD/LDAC) for lossless streaming from smartphones, TVs, or computers.
    • Outputs: Speaker terminals (banana/plug), subwoofer pre-out, and headphone jack for flexible setups.
  3. User-Centric Design
    • Intuitive front-panel controls or remote interface for adjusting volume, input selection, and EQ (bass/treble tone controls).
    • Compact form factor (often 10–14 inches wide) fits seamlessly into bookshelves, media consoles, or desktop setups. 

Why Choose a Stereo Amplifier?

  • Simplicity: No need for separate preamps or power amps—just plug in sources and speakers.
  • Cost-Effective: Combines multiple components at a lower price than buying them individually.
  • Space-Saving: Perfect for apartments, dorm rooms, or anyone prioritizing aesthetics over complexity. 
An integrated stereo amplifier is more than a component—it’s the heart of a cohesive audio system, blending technical precision with everyday usability. Whether you’re rediscovering vinyl, building a compact theater, or simply enjoying your favorite playlists, it delivers timeless performance in a modern package.
