Dropper  3ml Plastic (Pasteur Pipette)

The 3ml plastic Pasteur pipette, also commonly known as a dropper, is a simple yet useful tool for transferring small volumes of liquids. This versatile piece of equipment is often made of low-density polyethylene (LDPE) plastic, making it lightweight, disposable, and cost-effective.

Built for Convenience:

• Plastic Construction: LDPE plastic offers several advantages. It’s lightweight, making the dropper easy to handle. It’s also generally resistant to many chemicals (refer to manufacturer’s specifications), allowing it to be used with various liquids. Because it’s disposable, there’s no need for cleaning after use, reducing the risk of contamination.
• Size and Capacity: The 3ml capacity makes it suitable for transferring small to moderate amounts of liquids. The dropper itself is typically around 15-17 cm long, offering a comfortable grip and reach for most applications.
• Graduated Markings (Optional): Some models might have printed markings along the side to indicate the volume of liquid drawn into the dropper. This can be helpful for tasks requiring a more precise measurement.
• Simple Design: The dropper consists of a single, elongated plastic tube with a pointed tip for controlled dispensing and a bulb at the other end.

Functionality:

1. Filling the Dropper: Squeeze the bulb to expel air from the dropper. Release the pressure, and the dropper body will fill with liquid by capillary action as you dip the tip into the liquid source.
2. Dispensing the Liquid: Once filled, gently squeeze the bulb to control the flow. The liquid will dispense from the pointed tip in drops or a small stream, depending on the pressure applied.

Applications:

Due to its ease of use and disposable nature, the 3ml plastic Pasteur pipette finds uses in various scenarios:

• Scientific Experiments: Transferring small volumes of solutions, cultures, or reagents in laboratories.
• Arts and Crafts: Adding drops of paint, glue, or other craft liquids for creative projects.
• Applying Essential Oils or Fragrances: These droppers can be used for measured application of essential oils in aromatherapy or adding fragrance oils to DIY projects (always follow specific instructions and dilution recommendations).
• Food Applications: Decorating pastries, adding flavorings, or measuring small amounts of liquids in recipes.
• Watering Delicate Plants: Delivering precise amounts of water to seedlings or small plants.
