Stage Size:** 124 x 153mm; Transverse movement: 70mm, Longitudinal movement: 50mm **8. Illumination:** 6V 20W built-in variable brightness lamp --- **Structure:** 1. **Mounting:** The base supports the entire weight of the microscope and features four rubber feet for stability. 2. **Illumination System:** Equipped with a 6V 20W variable brightness lamp to ensure optimal lighting and resolution. The condenser has two parts, one mounted on the trestle and the other on the base, with adjustment screws for alignment. 3. **Mechanical Stage:** Allows precise transverse and longitudinal movement of the specimen. 4. **Eyepiece, Objective, and Nosepiece:** The nosepiece allows quick switching between objectives, ensuring consistent centering and focusing. The eyepiece tube is inclined at 45 degrees for comfortable viewing. 5. **Coarse and Fine Focus Equipment:** Features coaxial controls located below the stage for easy operation. Includes a fine focus stopper and tension adjustment knob for precision. --- **Usage Instructions:** 1. Rotate the objectives into the nosepiece according to their magnification. Insert the eyepieces into the inclined eyepiece tube. 2. Place the specimen on the stage and center it under the objective. 3. Start with the 10X objective, adjust the coarse focus until the image comes into view, then use the fine focus for clarity. 4. Remove the lower condenser and use the plan-concave mirror for alternative illumination if needed. --- **Complete Set Includes:** | Item No. | Contents | Quantity | |----------|-------------------------------|----------| | 1 | Main Body | 1 Set | | 2 | Eyepiece WF10X, P16X | 2 pcs | | 3 | Objective 4X, 10X, 40X, 100X | 1 pc | | 4 | Reflecting Mirror | 1 pc | | 5 | Spare Lamp | 1 pc | | 6 | Spare Fuse | 1 pc | | 7 | Cedar Oil | 1 Bottle | | 8 | Operation Manual | 1 Copy | --- **Maintenance Tips:** 1. Store the microscope in a cool, dry, dust-free, and acid-free environment. Cover it with a dust cover after use. 2. Do not disassemble the lenses. Clean them with alcohol if necessary, but avoid getting liquid inside the objectives. Use a soft brush to remove dust. 3. The coarse and fine focus mechanisms and nosepiece are precisely engineered—do not dismantle them without permission. 4. When not in use, store the objectives in their case and cover the eyepiece tube with a protective cover.

Single Layer Airless Bottle

Single layer airless bottle is a type of packaging container that is designed to keep the contents inside fresh and free from air exposure. Single layer airless bottle consists of a single layer of material, typically plastic, that is air-tight and prevents any air from entering the bottle.

The airless design of this bottle helps to preserve the quality and effectiveness of the products inside, such as skincare creams, lotions, and serums. By eliminating air exposure, the risk of oxidation and contamination is reduced, prolonging the shelf life of the product.

The single layer airless bottle typically features a pump mechanism that dispenses the product without the need for air to enter the bottle. This ensures that the contents are protected from exposure to air, light, and other external factors that can degrade the product over time.

Overall, the single layer airless bottle is a popular choice for packaging sensitive and high-quality products, as it provides an effective barrier against air and helps to maintain the product's integrity and efficacy.
