Envirochek Polyester HV Sampling Capsule, Indiv. Pkd, 25/Pk SKU: 12098

Polyester (PET) Capsule Filters - 12098

Environmental capsule filters provide the high-volume water processing capacity needed for regulatory sampling methods, with construction designed to withstand field transport and deployment conditions. 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. With this in mind, the outcome is simplified regulatory documentation and reduced contamination risk, with each single-use capsule providing a validated, traceable filtration event.

Key Polyester (PET) Membrane Characteristics

• Polyester membrane capsules provide chemical resistance to aqueous solutions, dilute acids, bases, and alcohols, with mechanical durability suited to environmental and industrial sampling applications.
• The hydrophilic polyester membrane wets readily with aqueous solutions, enabling efficient filtration of water samples and environmental matrices without pre-conditioning.
• Non-sterile capsules support autoclave sterilization where the membrane and housing materials permit, allowing users to prepare devices according to their own validated sterilization protocols.
• The 100 psi maximum pressure rating accommodates the differential pressures generated during filtration of particle-laden solutions as the membrane progressively loads.
• 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.

Key Capsule Construction Features

• Polycarbonate housing provides high-impact strength and optical transparency, enabling visual monitoring of fluid flow and membrane wetting during filtration operations.
• Polycarbonate capsule housing delivers the mechanical durability needed for repeated handling in field sampling and environmental monitoring applications.
• The rigid polycarbonate housing withstands the physical demands of field deployment, transportation, and connection to portable sampling equipment in remote locations.
• Polycarbonate construction provides a low-extractable housing suitable for aqueous environmental and biological sample processing applications.

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. If your monitoring program requires high-volume water collection at remote field sites, environmental sampling capsules provide the flow capacity and physical durability your regulatory methods demand. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Sterilization Guidance

Non-sterile delivery and non-autoclavable housing construction position the device for applications where particle removal and sample clarity are the primary objectives rather than sterile effluent production.
