It is widely used in RC airplanes, helicopters, cars, and robotics. It offers roughly stall torque, operates on , and is commonly controlled via PWM (0-180 degrees).

The TowerPro SG90 is a popular, lightweight (9g) 180-degree micro servo motor designed for precise, small-scale robotics and DIY projects, commonly used with Arduino. Operating at 4.8V-6V, it offers a stall torque of ~1.2-1.8 kg/cm and connects via three wires: Brown (Ground), Red (5V), and Orange/Yellow (PWM signal).

Key Features and Properties: Composition: Composed mainly of agarose and agaropectin, derived from red algae such as Gelidium and Gracilaria. Gel Properties: Reversible gelation; it melts at and solidifies at . Transparency: Produces clear gels, facilitating the observation of roots and contamination. Physical Properties: High gel strength ensures stable support during development. Purity: Specifically refined to remove impurities that could affect plant growth.

Basket-Rack Assembly: Contains 6 open-ended glass tubes, 75–80 mm long, with a 10-mesh stainless steel screen at the bottom. Motion: A motor drives the assembly to move up and down, typically 29–32 cycles per minute (or strokes/min) over a distance of 55–60 mm. Media Vessel: A 1-liter beaker, usually containing water or a gastric fluid simulation. Temperature Control: A built-in heating mechanism with an external probe ensures the medium remains at . Control Panel: Digital controls with, typically, a LED display, allowing independent control of multiple baskets.

Built-in Screen: Unlike standard microscopes, this system includes a frosted or clear screen (often a 160mm–200mm circular screen) that eliminates the need to look through an eyepiece. Light System: Features a high-intensity illumination system, often a 12V-100W halogen bulb, to project images clearly. Magnification: Typically utilizes a revolving nosepiece with multiple objective lenses (e.g., 5x, 10x, 20x, 40x), providing a wide range of magnifications for detailed observation. Stage Mechanism: Includes a mechanical stage with clips to hold slides securely, allowing precise movement for focusing. Projection Lens: A dedicated projector lens (distinct from the objective) magnifies the intermediate image onto the viewing screen.
