Laboratory Testing & Filter Analysis

Make more informed filtration decisions through controlled testing, product evaluation, and technical analysis.

Testing Designed Around Your Application

Selecting the right filter requires an understanding of the fluid, contaminant, operating conditions, and desired filtration result. Strainrite works with customers to evaluate non-hazardous fluid samples and compare filtration options before moving into full-scale production trials.

Testing may help determine the appropriate filter media, micron rating, construction, and surface area for the application. Our technical team reviews the results with you and recommends a practical path forward based on filtration performance and total operating cost.

Testing Designed Around Your Application

Customer Sample Testing

Strainrite accepts qualifying non-hazardous fluid samples for laboratory-scale filtration testing. Depending on the application and available sample volume, our team can evaluate how different filter media and configurations perform against the customer’s desired outcome.

Testing can support:

Filter media and micron-rating selection
Comparative filtration trials
Product-clarity and contaminant-removal evaluations
Troubleshooting of filter life or process performance

All samples are reviewed and approved before shipment to confirm that they can be handled safely within our facility.

Filter Dissection and Product Analysis

When customers want to understand an existing filtration product, Strainrite can dissect and evaluate unused filter elements. Our team examines the filter’s construction, dimensions, media configuration, support components, seals, and other design characteristics.

This analysis helps us identify the product’s likely performance characteristics and determine whether Strainrite can provide a comparable or improved filtration solution.

For safety and analytical consistency, filter dissection is generally limited to new, unused elements unless otherwise approved in advance.

Product Validation and Quality Testing

Strainrite performs product-specific testing to validate the performance of applicable filter lines. Depending on the product, supporting documentation may include integrity-test data, bacterial-retention studies, biological-reactivity testing, endotoxin testing, extractables data, and sterilization-cycle evaluations.

Validation guides and supporting documentation are available for select pharmaceutical and life-science product families upon request. Testing methods and available documentation vary by product.

Vessel and Housing Quality Assurance

Filtration housings are manufactured under Strainrite’s ISO 9001-certified quality-management system and hydrostatically tested according to applicable design and customer requirements.

Additional nondestructive examination—including radiographic, ultrasonic, magnetic-particle, liquid-penetrant, and hardness testing—is available when required by the vessel design or customer specification.

Why Our Testing Sets the Standard

100% Factory Integrity Testing

Every pharmaceutical-grade filter is integrity tested at our factory before shipment. No sampling, no shortcuts — each unit is individually verified to meet performance specifications.

USP & cGMP Compliance

Our filters are tested and certified to USP Class VI Biological Reactivity standards, USP Physicochemical Tests for Plastics, and manufactured under cGMP and ISO 9001-certified quality management systems.

Steam Sterilization Durability

Products are audit tested to verify integrity after exposure to 20–25 one-hour steam cycles at 135°C (275°F), ensuring reliable performance through repeated sterilization in demanding production environments.

Third-Party Validated Clean Rooms

All pharmaceutical-grade filters are manufactured and tested in independently validated clean room facilities, maintaining the controlled environment necessary for products used in critical life science and biotech applications.

Why Strainrite for Lab Testing & Analysis

Bacterial Retention & Integrity Correlation

Our sterilizing-grade filters undergo documented bacterial retention testing using Brevundimonas diminuta challenge at concentrations of 10⁷ CFU/cm². Each product line includes correlation data linking bacterial challenge results to non-destructive integrity tests, enabling reliable in-process verification.

Endotoxin & Biocompatibility Testing

Every applicable filter is tested using the Limulus Amebocyte Lysate (LAL) method to verify endotoxin levels below 0.0050 EU/ml. Cytotoxicity testing and USP Class VI Biological Reactivity In Vivo testing confirm the biocompatibility of our materials for pharmaceutical and biotech use.

Advanced Materials Testing

For vessels and housings, we go beyond standard quality checks with specialized non-destructive testing: X-ray inspection, magnetic particle examination, liquid penetrant analysis, ultrasonic evaluation, and Brinell hardness testing — ensuring structural integrity under the most demanding operating conditions.

Complete Validation Packages

Validation guides are available on request for our key pharmaceutical product lines, including the Pur-MAXX SG, Vent-MAXX, Endo-MAXX CN, and MAXX-Cap series. Each package documents bacterial retention, integrity test data, cytotoxicity, LAL results, and USP compliance — streamlining your regulatory submissions.

ISO 9001-Certified Quality System

Our entire manufacturing and testing operation runs under an ISO 9001-certified Quality Management System. From raw material receiving through final inspection and shipment, state-of-the-art equipment and highly skilled technicians maintain the highest levels of product reliability and repeatability.

How the Process Works

Discuss the Application

We begin by reviewing the fluid, current filtration process, operating conditions, performance concerns, and desired outcome.

Approve the Sample or Filter

Before anything is shipped, Strainrite confirms that the sample or unused filter element can be safely received and evaluated.

Test & Analyze

Our technical team performs the agreed-upon testing or filter analysis and documents the relevant observations.

Review the Findings

We review the findings with you and recommend the filter media, product configuration, or next-stage production trial that best fits the application.
