At every stage of the filtration process — including pre-filtration, bioburden reduction, sterilization, tank vent and gas filtration, endotoxin removal, and trap filtration — Strainrite's filters deliver superior performance and consistently high-quality results.

Strainrite's pharmaceutical-grade filters are manufactured under rigorous quality controls and are designed to comply with industry regulations and validation requirements. Whether you are producing sterile injectables, biologics, vaccines, or other critical formulations, our products provide the reliability and reproducibility your process demands.

Key Filtration Stages

Each stage requires precision engineering and validated performance to ensure product safety and full regulatory compliance.

01

Prefiltration

Strainrite's Clarity Depth (2.5"-2.7" diameter) and Clarity Continuous Pleated series offer quality depth filtration in an array of filter media:

  • Polypropylene
  • Sterilizing-Grade Polyether Sulfone

02

Bioburden Reduction

Strainrite's Clarity Membrane (2.5-2.7" diameter) series offer quality bioburden reduction in your choice of filter media:

  • Polyethersulfone
  • Polysulfone
  • Nylon
  • Charged Nylon
  • PTFE
  • Cellulose
  • Micro-Glass Depth over Membrane
  • Polypropylene Depth over Membrane

03

Sterilization

Strainrite's sterile-grade Clarity's Mem-Pleat E-SG (2.5" diameter) and Pur-MAXX E-SG (2.7" diameter) filters offer validated sterile filtration in a dual-layer pleated polyethersulfone sterile membrane element — providing reliable 0.2 µm absolute bacterial retention.

04

Tank Vent & Process Gas Filtration

Strainrite offers the highest quality tank vent and process gas filtration with hydrophobic, sterilizing PTFE membrane vent filters, Vent-Rite (single-layer PTFE), and Vent-MAXX (double-layer PTFE).

Single Use Filtration:

Single Use Filtration:

Strainrite also offers single-use and multi-use application capsules, available in sizes from 5" to 40". These are used in a wide range of industries from ophthalmics to food and beverage processing inks. Capsules can house a wide array of materials from the innovative sterilizing grade polyethersulfone to our charged modified nylon, as well as absolute and nominal media like polypropylene and microglass.

Made of 100% polypropylene, Strainrite's capsule design incorporates thermal bonding. Thermal bonding provides an integral fit that requires no glues, binders, surfactants or adhesives. This design ensures low extractable filtration when incorporated with our low extractable 100% clean room manufactured cartridges.

Quality & Regulatory Compliance

Strainrite operates under internationally recognized quality and manufacturing standards to ensure consistent performance, regulatory alignment, and contamination control for critical applications.

ISO 9001:2015 Certified Quality Management System

Strainrite's ISO 9001:2015 certification means its entire quality management system is built around documented, standardized processes that are audited by an accredited third party on a regular basis. The standard requires Strainrite to define and control everything from design and purchasing through manufacturing, inspection, and customer support, and to keep records that demonstrate filters consistently meet both customer and regulatory requirements.

It also emphasizes risk-based thinking and continuous improvement, so Strainrite must monitor performance, investigate nonconformities, and implement corrective actions to prevent issues from recurring and to steadily improve reliability and customer satisfaction over time.

cGMP Manufacturing in Validated Clean Rooms

Operating under current Good Manufacturing Practices (cGMP) in validated clean rooms means Strainrite's production environment and procedures follow stringent controls similar to those used in regulated industries such as pharma and biotech.

cGMP expectations include written procedures for every critical step, training and qualification of personnel, traceability of materials and lots, and documented evidence that equipment, processes, and cleaning methods work as intended and are kept in a validated state. Clean room validation adds another layer of assurance: air quality, particulate levels, pressure differentials, and environmental conditions are tested and routinely monitored, helping ensure Strainrite's filtration products are manufactured in a controlled environment suitable for sensitive, contamination-critical applications.
