Diamond PosiStop LTS Compatible Filter Pipette Tips, 200ul, Low-Retention, Sterile, Graduated, 96/Rack, 10 Racks/Box

Description

Product Overview

Diamond PosiStop LTS Compatible Filter Pipette Tips are engineered for laboratories that demand precision, reliability, and cleanliness in every liquid handling step. Each tip holds 200 µL of fluid and features a low‑retention design that minimizes sample loss, a critical factor when working with scarce or expensive reagents. The tips are sterile, graduated, and manufactured from medical‑grade virgin polypropylene, ensuring they are free from DNase, RNase, pyrogens, PCR inhibitors, and endotoxins. Packaged in a convenient 96‑tip rack, the tips are ready for immediate use, reducing setup time and the risk of cross‑contamination.

These tips are specifically compatible with Diamond PosiStop and Rainin LTS pipettors, providing a positive stop seal that eliminates air gaps and improves volume accuracy. The unique positive‑stop cylinder design creates a secure connection between the pipettor and tip, delivering consistent performance across thousands of aspirate‑dispense cycles. The product dimensions are 13.78 x 7.48 x 5.12 inches, and the total weight is approximately 4 pounds, making it easy to store and transport within standard laboratory environments.

Usage

These filter pipette tips are ideal for a wide range of molecular biology applications, including PCR, qPCR, RT‑PCR, DNA/RNA extraction, and enzyme assays. The low‑retention property ensures that even the smallest volumes are transferred accurately, which is essential for quantitative experiments and high‑throughput screening. The sterile nature of the tips makes them suitable for cell culture work, where contamination control is paramount, as well as for clinical diagnostics that require stringent aseptic conditions.

Laboratories can integrate the 96‑rack format into automated liquid handling systems, allowing for seamless integration with robotic platforms. The graduated markings on each tip provide visual confirmation of volume settings, supporting manual pipetting workflows where precision is required. Whether you are a research scientist, a quality control analyst, or a technician in a core facility, these tips streamline your workflow by reducing the need for additional filtration steps and minimizing the risk of sample degradation.

FAQ

Are these tips compatible with pipettors other than Diamond PosiStop?

Yes, the tips are also compatible with Rainin LTS pipettors and any other LTS‑style pipettors that use a positive‑stop mechanism, providing flexibility across different brands.

What does low‑retention mean for my experiments?

Low‑retention means the interior surface of the tip is engineered to reduce liquid adhesion, which helps prevent sample loss and improves the accuracy of small‑volume transfers, especially important for quantitative PCR and enzyme assays.

How are the tips sterilized?

The tips are gamma‑irradiated in a controlled environment to achieve a sterile state without compromising the integrity of the polypropylene material.

Can I use these tips for cell culture applications?

Absolutely. The sterile construction and endotoxin‑free certification make the tips suitable for cell culture, tissue sampling, and other aseptic techniques.

What is the shelf life of the product?

When stored in a cool, dry place away from direct sunlight, the tips retain their performance characteristics for up to 24 months from the date of manufacture.
