Description
Product Overview
The Glass Microfiber Filter 1.2µm 9cm PK100 from Lab Safety Supply is engineered for high‑precision laboratory filtration. Constructed from premium glass microfiber media, the filter provides a uniform pore structure that reliably captures particles as small as 1.2 microns while allowing a smooth airflow that minimizes pressure loss. Its compact 9 cm diameter and 1.2 µm rating make it compatible with a wide range of standard lab filtration housings, enabling seamless integration into existing workflows. The filter is supplied in a convenient PK100 pack, ensuring that laboratories have a ready stock of consistent, high‑quality elements for routine analyses, method development, and critical sample preparation. Manufactured in the United States under strict quality‑control protocols, each unit meets ASTM and ISO standards for glass fiber filtration, delivering repeatable performance that scientists can trust for chemical, microbiological, and environmental testing.
Durability and chemical resistance are core attributes of the glass microfiber construction. The fibers are fused at high temperature, creating a stable matrix that resists degradation when exposed to acidic or basic solutions, solvents, and high‑temperature steam sterilization cycles. This resilience extends the service life of each filter element, reducing the frequency of replacement and lowering overall operating costs for busy research facilities. In addition, the filter’s low extractable profile minimizes the risk of contaminant leaching, a critical consideration for trace‑level analyses where background interference must be kept to an absolute minimum. The PK100 packaging includes individually sealed units that protect the media from moisture and particulate exposure during storage and transport, guaranteeing that the filter arrives ready for immediate use.
Extensive testing validates the filter’s performance across a range of flow rates and particle loads. Independent laboratory evaluations have confirmed that the 1.2 µm rating consistently meets or exceeds the specifications required for high‑purity applications, while the pressure drop remains well within acceptable limits for most pump and vacuum systems. Certification data, including compliance with ISO 11171 for glass fiber filters, is available upon request, providing additional assurance for quality‑focused organizations.

Usage
The Glass Microfiber Filter is ideally suited for a variety of laboratory environments, including analytical chemistry, microbiology, and environmental monitoring. Its compact size allows it to be installed in standard filter housings, syringe filters, and vacuum manifolds without requiring custom adapters. Researchers can employ the filter for sample preparation steps such as removing particulates before chromatography, protecting sensitive detectors from clogging, and ensuring that downstream assays receive a clean, particle‑free solution.
In microbiological work, the filter’s fine pore size effectively retains bacteria, spores, and fungal fragments while permitting the passage of clear liquid media. This capability is essential for sterility testing, cell culture filtration, and the preparation of inoculum‑free samples for downstream molecular analysis. The low pressure drop also helps maintain cell viability when filtering live cultures, as excessive shear forces are avoided.
Environmental testing laboratories benefit from the filter’s ability to handle a wide range of sample matrices, from aqueous river water to soil extract suspensions. The robust glass fiber media tolerates high turbidity and variable pH, making it a reliable choice for field‑deployed kits that must operate under diverse conditions. Its compatibility with both low‑volume syringe setups and larger batch filtration systems provides flexibility for scaling analytical protocols.
For high‑throughput workflows, the PK100 pack ensures that a consistent supply of identical filter elements is always on hand, reducing downtime caused by inventory shortages. The sealed packaging protects the filters from humidity and airborne contaminants, preserving performance even after extended storage periods. Users can quickly replace spent filters, maintaining continuous operation of critical instrumentation.

FAQ
What types of liquids can be filtered with this glass microfiber filter?
The filter is compatible with a broad range of aqueous and organic liquids, including acidic, basic, and solvent‑based solutions. Its chemically resistant glass fiber media tolerates most laboratory reagents, making it suitable for sample preparation, chromatography, and microbiological applications.
Can the filter be sterilized for reuse?
Yes, the glass microfiber construction can withstand autoclave cycles at typical sterilization temperatures (121 °C) without degradation of pore structure. However, for critical applications where cross‑contamination risk must be eliminated, we recommend using a fresh filter element.
Is the filter compatible with standard syringe filter housings?
Absolutely. The 9 cm diameter aligns with common syringe and vacuum filter housings used in most laboratories. Adapters are not required, and the filter can be installed quickly by following the manufacturer’s standard mounting instructions.
How does the filter’s performance compare to polymer‑based filters?
Glass microfiber filters generally provide superior thermal stability and chemical resistance compared to polymer alternatives. They also exhibit lower extractable content, reducing background interference in trace‑level analyses. While polymer filters may be suitable for low‑cost, single‑use scenarios, our glass microfiber filter offers consistent performance and longer service life for demanding laboratory workflows.
What warranty or after‑sales service is offered?
Lab Safety Supply provides a limited one‑year warranty covering manufacturing defects. If a filter fails to meet the specified performance criteria, our support team will arrange a replacement or provide technical assistance to resolve the issue promptly.
