*Industry Knowledge Development*
Rainin pipette tips are high-quality disposable tips used in laboratories for accurate and precise liquid handling during pipetting procedures.

Rainin pipette tips are designed to fit Rainin pipettes, which are known for their ergonomic design and performance. The tips come in various sizes and types to accommodate different volumes and applications. Some common types of Rainin pipette tips include:
1.Universal tips: These tips are designed to work with a wide range of Rainin pipettes and are suitable for general laboratory use.
2.Filtered tips: These tips have built-in filters to prevent contamination of the pipette and sample by aerosols or liquids. They are commonly used when working with sensitive samples or when handling PCR reactions.
3.Low retention tips: These tips are specially treated to minimize liquid retention, ensuring accurate and efficient pipetting. They are often used when working with expensive or viscous liquids to minimize sample loss.
4.Extended length tips: These tips have a longer length compared to standard tips, allowing for pipetting into deep or narrow containers, such as microcentrifuge tubes or PCR tubes.

Rainin pipette tips are manufactured using high-quality materials, such as virgin polypropylene, to ensure excellent chemical resistance and compatibility with a wide range of reagents. They are precision-molded to provide a secure and leak-proof seal with the pipette, preventing sample contamination and ensuring accurate dispensing.

When working with Rainin pipettes, it is important to use compatible Rainin pipette tips to ensure optimal performance and accurate results. It is recommended to always refer to the manufacturer's instructions for proper tip usage, including the maximum volume and compatibility with specific pipettes.

Rainin pipette tips are commonly used in laboratories for accurate and precise liquid handling during various scientific procedures. These tips are designed to fit onto Rainin pipettes, which are adjustable-volume pipettes used for dispensing liquids in precise volumes.

The Rainin pipette tip consists of a slender, tapered plastic tube with a small opening at one end and a wider opening at the other. The wider opening is designed to fit securely onto the pipette nozzle. The tip is made of a high-quality, low-retention polypropylene material to ensure minimal sample retention and accurate transfer of liquids.

The working principle of a Rainin pipette tip involves a combination of air displacement and positive displacement. When the pipette is operated, a plunger inside the pipette creates a vacuum by retracting the air, which draws the liquid into the tip. The liquid enters through the small opening of the tip, and the tip's design prevents any leakage or backflow.

Once the desired volume of liquid is drawn into the tip, the pipette is used to transfer the liquid to the desired location. When the plunger is depressed, it creates positive pressure inside the pipette, pushing the liquid out of the tip and into the target vessel. The tapered design of the tip allows for precise and controlled dispensing of the liquid without any dripping or splashing.

Rainin pipette tips come in various sizes to accommodate different volumes of liquid. They are typically designed for single-use, disposable applications to prevent cross-contamination between samples.

It's worth noting that while Rainin pipette tips are widely used and provide reliable liquid handling, there are also other brands and types of pipettes and pipette tips available on the market, each with their own specific design and operation principles.
