Disposable Sterile Serological Pipettes 25ML LUERFLEX Pack of 50

Description

Product Overview

The LUERFLEX 25ML disposable sterile serological pipettes are engineered for high‑precision liquid handling in demanding laboratory environments. Each pipette is individually sealed in a paper‑plastic pouch that maintains a sterility assurance level of SAL 10‑6, ensuring that every transfer is free from microbial contamination. The packaging dimensions of 16.18 x 5.2 x 5.2 inches and a lightweight 2.12‑pound total weight make storage and inventory management straightforward for busy research facilities.

Constructed from ultra‑pure polystyrene that complies with USP VI standards, these pipettes provide excellent chemical resistance and structural integrity. The material choice eliminates the risk of leaching, preserving sample purity across a wide range of reagents, including acids, bases, and organic solvents. The clear, two‑way graduation lines are printed with high‑contrast ink, allowing users to read volumes from both the top and bottom of the pipette, reducing errors caused by parallax.

Color‑coded circles on the shaft of each pipette correspond to specific volume ranges, simplifying the selection process for technicians who work with multiple pipette sizes throughout the day. The 25ML capacity strikes a balance between volume flexibility and ease of handling, making it suitable for applications such as cell culture media preparation, reagent dilution, and sample aliquoting. The product model number 1044002 is referenced in the manufacturer’s catalog for quick cross‑reference and ordering.

Performance testing conducted by independent laboratories confirms that the pipettes meet stringent accuracy and precision specifications, with a coefficient of variation well within acceptable limits for serological work. The product’s best‑seller rank of #10 in the Serological Pipettes subcategory reflects its popularity among scientific professionals who prioritize reliability and consistency.

Usage

These pipettes are ideal for a broad spectrum of laboratory tasks, ranging from routine buffer preparation to complex assay development. Researchers in microbiology, biochemistry, and molecular biology can rely on the sterile barrier to prevent cross‑contamination when handling pathogenic samples or sensitive reagents. The 25ML volume is particularly advantageous for medium‑throughput workflows, where larger aliquots reduce the number of pipetting steps and improve overall efficiency.

In quality‑control laboratories, the clear graduations and color‑coded markings enable rapid verification of volume delivery, supporting compliance with Good Laboratory Practice (GLP) standards. The individually wrapped design also facilitates sterile field setup in biosafety cabinets, as technicians can quickly retrieve a pipette without exposing the entire batch to the environment.

Because the pipettes are disposable, they eliminate the need for cleaning, autoclaving, or decontamination between uses, saving valuable time and reducing the risk of residual contamination. This feature is especially valuable in high‑throughput screening facilities where turnaround time is critical.

FAQ

What does SAL 10‑6 mean for my experiments?

SAL 10‑6 indicates a one‑in‑a‑million probability that a viable microorganism remains on the pipette after sterilization, offering a high level of confidence for sterile work.

Can these pipettes be used with organic solvents?

Yes, the USP VI‑grade polystyrene material is resistant to a wide range of solvents, including ethanol, methanol, and many acids and bases commonly used in laboratory protocols.

How do I verify the accuracy of the graduations?

The pipettes are calibrated during manufacturing to meet industry‑standard tolerance levels. For additional verification, users can perform a gravimetric test by weighing water dispensed at a known volume.

Are the color codes standardized across all sizes?

Each size range uses a distinct color circle to aid quick identification. The 25ML size is marked with a specific color that is consistent across all LUERFLEX product lines.

What is the recommended storage condition?

Store the pipettes in a cool, dry place away from direct sunlight. The sealed packaging protects the sterility and prevents moisture absorption, preserving performance over the product’s shelf life.
