Transport bag FEP®

samplingwith valvepolypropylene

Product overview
FEP® (fluorinated-ethylene-propylene) film gas sampling bags for industrial and field sampling. Chemically inert and usable across a wide temperature range (-400°F to 400°F). Film gauge 0.005" tolerates rough handling. Available in volumes from 0.6 L to 100 L with multiple valve and fitting options for laboratory and field workflows.

FEP® film properties

• Chemically inert
• Minimal sample loss
• No plasticizers
• Reusable and cleanable
• Leak tested
• Non-contaminating
• Mechanically strong (heavier gauge)

Valve combinations and available volumes (examples)

• Screw Cap Combo Valve with Septum — PNs include UGSF001P-0606S (0.6 L) through UGSF001P-3036S (100 L); typical pack amounts: 3–10 depending on PN
• Locking Combo Valve with Septum — PNs include UGSF001P-0606 (0.6 L) through UGSF001P-3036 (100 L); typical pack amounts: 3–10 depending on PN

Gas bag fittings
Polypropylene screw-cap combo valve

• On/Off valve with replaceable fluoropolymer-faced, low-bleed silicone septum and side port for tubing
• Lightweight and cost-effective for carrying multiple bags in the field
• Inert polypropylene construction preserves sample purity
• Quick open/close operation (less than half turn) with visual open/closed indicator

Polypropylene Locking® combo valve with septum

• On/Off valve with replaceable fluoropolymer-faced, low-bleed silicone septum; allows repeated syringe punctures without leakage
• Push/pull valve stem for rapid operation (<1 second) and quick locking without tools
• Lightweight, inert polypropylene construction

Stainless steel TCLP fitting with septum

• Stainless steel body with aluminum cap and replaceable fluoropolymer-faced septum
• Durable for austere sampling conditions; designed for use with Zero Headspace Extractors
• Validated fitting style for EPA TCLP method

Stainless steel combo valve with replaceable septum

• Combines on/off valve and septum in a single fitting to reduce cost and weight
• Stainless steel body with aluminum cap; sample contacts only stainless steel and fluoropolymer

Swagelok® type stainless steel fitting for tubing or septum

• Stainless steel construction for durability in harsh conditions
• Allows attachment of tubing or syringe extraction by switching caps
• Replaceable fluoropolymer-faced septum with large area for repeated syringe punctures

Plastic Jaco® fitting for tubing or septum

• Polypropylene compression ferrule secures tubing with superior grip compared to metal ferrules
• Cost-effective alternative to metal fittings
• Allows tubing attachment or syringe extraction; replaceable fluoropolymer-faced septum

PFA fitting for tubing or septum

• PFA fluoropolymer construction so sample contacts only high-purity inert fluoropolymer PFA
• Compression ferrule secures tubing; allows syringe extraction by switching caps
• Replaceable fluoropolymer-faced septum with large area for repeated syringe punctures

Nickel plated Halkey® Roberts barbed on/off valve

• Nickel plated to resist aggressive chemicals
• Barbed stem for tubing attachment
• Leak-resistant seal prevents sample loss when closed
