Envirochek Polyester HV Sampling Capsule, 1/Pk SKU: 12099

Polyester (PET) Capsule Filters - 12099

Environmental sampling capsules are purpose-built for high-volume water collection in field and laboratory settings where regulatory monitoring programs define the filtration requirements. Additionally, capsule construction designed for field deployment withstands the transport, handling, and connection conditions encountered at remote groundwater wells, surface water stations, and portable sampling installations. The outcome is higher operational throughput with lower contamination risk, as disposable capsule devices remove the reprocessing steps that introduce variability into reusable filter systems.

Key Polyester (PET) Membrane Characteristics

• Rated for operating pressures up to 100 psi, the capsule housing withstands the system pressures encountered in peristaltic pump, pressure vessel, and gravity-feed filtration configurations.
• The hydrophilic polyester membrane wets readily with aqueous solutions, enabling efficient filtration of water samples and environmental matrices without pre-conditioning.
• The mechanical strength of polyester membranes supports sustained filtration under the operating pressures and flow rates encountered in high-volume environmental sampling protocols.
• The single-layer configuration delivers efficient filtration of clean solutions at lower differential pressures than dual-layer alternatives, supporting gravity-feed and low-pressure applications.
• Polyester filter media provides low protein binding characteristics, minimizing analyte loss during filtration of biological and environmental samples.

Key Capsule Construction Features

• Sealed polycarbonate capsule construction is individually integrity-tested during manufacturing, verifying membrane retention and housing seal quality before shipment.
• Transparent polycarbonate construction allows operators to confirm complete air displacement and track filtration progress without interrupting the process or breaking connections.
• The rigid polycarbonate housing withstands the physical demands of field deployment, transportation, and connection to portable sampling equipment in remote locations.
• Polycarbonate housing provides high-impact strength and optical transparency, enabling visual monitoring of fluid flow and membrane wetting during filtration operations.

Whether your process requires sterilizing-grade retention for a 500-milliliter bench trial or clarification capacity for a 100-liter production batch, the right capsule filter configuration eliminates the compromises between throughput, retention, and operational simplicity. For groundwater, surface water, and compliance sampling programs, purpose-built environmental capsules deliver the collection volumes and field-ready construction your sampling protocols specify. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Sterilization Guidance

Supplied non-sterile, the housing construction does not support autoclave sterilization and is intended for clarification, prefiltration, and general laboratory applications where sterile effluent is not required.
