EarthOx Sterile Serological Pipettes 25ml Long Packaged 20pcs

Description

Product Overview

The EarthOx 25ml long sterile serological pipettes are engineered to meet the rigorous demands of modern in‑vitro laboratory environments. Constructed from high‑quality, medical‑grade polymer, each pipette offers a clear, chemically resistant body that ensures no interaction with samples. The graduations are calibrated to provide dispensing accuracy within ±2%, and the bidirectional scale includes negative graduations for added flexibility, allowing users to measure volumes both above and below the zero mark. Each pipette comes equipped with a sterile, non‑pyrogenic filter plug that prevents aerosol contamination while maintaining sample integrity. Individually packaged, the pipettes remain sterile until the moment of use, guaranteeing a contaminant‑free experience for critical assays, cell culture work, and microbiological testing. The 338.9 mm (13.34 in) length provides an ergonomic grip, reducing hand fatigue during repetitive tasks, while the 25 ml capacity balances the need for sufficient volume with precise control.

Usage

These pipettes are ideal for a broad spectrum of laboratory applications, including cell culture media preparation, reagent dispensing, and sample transfer in molecular biology protocols. Their sterile nature makes them suitable for aseptic techniques, such as inoculating cell cultures, handling primary cells, and performing PCR setup where contamination control is paramount. The filter plug is particularly valuable when working with volatile or hazardous substances, as it captures aerosols and prevents cross‑contamination between samples. Researchers in academic, biotech, and pharmaceutical settings will appreciate the reliability of the calibrated graduations for quantitative experiments, while quality‑control labs can rely on the consistent performance for routine testing. The long design facilitates easy access to deep wells and flasks, and the robust construction ensures durability even under frequent autoclave cycles when re‑sterilization is required.

FAQ

What does sterile and non‑pyrogenic mean for these pipettes?

Sterile indicates that the pipettes are free from viable microorganisms, while non‑pyrogenic means they contain no fever‑inducing endotoxins. This combination ensures that the pipettes will not introduce contaminants or affect sensitive biological assays.

Can the filter plug be replaced after use?

The filter plug is designed for single‑use applications to maintain sterility. For repeated use, it is recommended to replace the entire pipette to avoid cross‑contamination.

Are these pipettes compatible with automated liquid handling systems?

Yes, the standard 25 ml size and calibrated markings make them suitable for many automated dispensers, provided the system can accommodate the pipette’s length and filter plug design.

What is the recommended storage condition for the pipettes?

Store the pipettes in a cool, dry place away from direct sunlight. Keep them in their original packaging until use to preserve sterility.

Do the pipettes meet any regulatory standards?

EarthOx serological pipettes comply with ISO 13485 and are manufactured under GMP conditions, ensuring they meet the quality requirements for laboratory and medical research applications.
