Cell Strainer by CELLTREAT Polypropylene Housing Nylon Mesh 229481

Description

Product Overview

The CELLTREAT Cell Strainer is engineered for laboratory professionals who demand precision, sterility, and durability in cell separation tools. Constructed from high‑grade polypropylene, the housing offers chemical resistance and a lightweight yet sturdy framework that withstands repeated autoclave cycles and routine handling. The integrated nylon mesh filter is gamma‑irradiated to ensure a sterile barrier, eliminating the need for additional decontamination steps before use.

Designed with an elongated lip that extends beyond the edge of standard centrifuge tubes, the strainer enables aseptic manipulation using forceps without compromising the integrity of the sample. An extended gripping tab on the housing provides a secure point of contact, reducing the risk of slippage during high‑speed centrifugation or when transferring delicate cell suspensions. The mesh porosity is color‑coded, allowing quick visual identification of the appropriate filter grade for specific cell sizes or experimental protocols.

Each unit is individually wrapped in a peel‑to‑open paper/plastic wrapper, preserving sterility until the moment of use. The product model number 229481 aligns with CELLTREAT’s cataloging system, ensuring compatibility with existing inventory management processes. With a best‑seller rank of #13 in Lab Cell Strainers, this device has earned a reputation for reliability among researchers in academic, biotech, and pharmaceutical settings.

Technical specifications include a compact package dimension of 15.12 x 9.57 x 5.12 inches and a negligible weight of 0.05 ounces, facilitating easy storage in crowded lab benches or reagent cabinets. The strainer’s design adheres to industry standards for cell filtration, providing a consistent flow rate and minimal shear stress on delicate cell populations.

Overall, the CELLTREAT Cell Strainer delivers a seamless blend of material science, ergonomic design, and quality assurance, making it a versatile component for a wide range of cell‑based assays, including viability testing, downstream purification, and media exchange procedures.

Usage

This strainer excels in environments where aseptic technique is paramount, such as tissue culture labs, cell therapy manufacturing suites, and academic research facilities. It is compatible with standard 15 ml and 50 ml centrifuge tubes, allowing researchers to process multiple samples concurrently without the need for custom adapters or additional filtration devices.

In routine cell culture workflows, the strainer can be employed to separate cells from culture media, harvest adherent cell layers, or filter out debris prior to downstream analysis. Its sterile nylon mesh ensures that contaminants are not introduced during the filtration step, preserving the purity of the cell population for sensitive downstream applications like flow cytometry or genomic sequencing.

Beyond cell culture, the device is suitable for processing tissue homogenates, enzymatic digests, and other biological suspensions where a defined pore size is required to retain target cells while allowing smaller particles to pass. The color‑coded mesh options simplify protocol development by providing a visual cue for selecting the appropriate filter grade, reducing setup time and minimizing errors.

FAQ

What tube sizes are compatible with this cell strainer?

The strainer is designed to fit standard 15 ml and 50 ml centrifuge tubes commonly used in cell culture and laboratory workflows. Its elongated lip ensures a secure fit without the need for additional adapters.

Can the mesh be replaced or cleaned for reuse?

The nylon mesh filter is intended for single‑use applications to maintain sterility and performance consistency. While the polypropylene housing can be cleaned and autoclaved, the mesh should be discarded after each use to prevent cross‑contamination.

How does the color‑coding system work?

Each mesh porosity is assigned a distinct color on the housing, allowing users to quickly identify the filter grade. For example, a blue‑coded housing may indicate a 40 µm pore size, while a red‑coded housing could represent a 20 µm pore size. Detailed color charts are provided in the product documentation.

Is the strainer suitable for GMP‑compliant processes?

Yes. The strainer meets GMP requirements through its sterile gamma‑irradiation, ISO‑9001 certified manufacturing, and traceable batch records. It is suitable for regulated environments such as biopharmaceutical manufacturing and cell therapy production.

What support does CELLTREAT provide if I encounter issues?
