Gas Sampling Bags with Valve Combination
Gas Bag Fittings
Polypropylene Screw-Cap Combo Valve
- On/Off valve function with replaceable septum in a single unit. Side port for tubing connection.
- Uses fluoropolymer-faced, low-bleed silicone septum.
- Inexpensive.
- Lightweight. Easier to carry multiple bags in the field.
- Made of inert polypropylene. Ensures sample purity.
- Quick, easy opening and closing of valve, even in harsh conditions with no tools required. Less than one half turn opens/closes valve.
- Visual confirmation that valve is open or closed prevents accidental sample loss.
Polypropylene Locking® Combo Valve with Septum
- On/Off valve function with replaceable septum in a single unit.
- Uses fluoropolymer-faced, low-bleed silicone septum. Allows repeated punctures with syringes without leakage.
- Inexpensive.
- Lightweight. Easier to carry multiple bags in the field.
- Made of inert polypropylene. Ensures sample purity.
- Push/Pull (On/Off) valve stem. Quick, easy opening and closing of valve (< 1 second). Faster than "twist-action" valves.
- Quick locking function requires no tools, and visual confirmation prevents accidental sample loss.
Stainless Steel TCLP Fitting with Septum
- Stainless steel body with aluminum cap and replaceable fluoropolymer faced septum.
- Durable: withstands use in austere sampling conditions.
- Inert: Sample contacts only stainless steel & fluoropolymer.
- Lower cost than 1/4″ Swagelok type fittings and nickel plated Halkey Roberts fitting.
- Designed for use with Zero Headspace Extractors.
- Validated fitting style for EPA TCLP (Toxicity Characteristic Leaching Procedure) method.
Stainless Steel Combo Valve with Replaceable Septum
- Design combines on/off valve and septum into a single fitting to lower cost & weight.
- Stainless steel body with aluminum cap and replaceable fluoropolymer faced septum.
- Durable: withstands use in austere sampling conditions.
- Inert: Sample contacts only stainless steel & fluoropolymer.
- Lower cost than 1/4″ Swagelok type fittings and nickel plated Halkey® Roberts fitting.
Swagelok® type Stainless Steel Fitting for Tubing or Septum
- Stainless steel construction. Durability and ability to withstand use in austere sampling conditions.
- Allows attachment of tubing or syringe sample extraction by switching caps.
- Replaceable fluoropolymer-faced septum with large area allows repeated punctures with common lab syringes.
Plastic Jaco® Fitting for Tubing or Septum
- Compression ferrule secures tubing onto fitting with superior grip compared to metal fittings.
- Polypropylene molded construction.
- Inexpensive compared to metal fittings.
- Allows attachment of tubing or syringe sample extraction by switching caps.
- Replaceable fluoropolymer-faced septum with large area allows repeated punctures with common lab syringes.
PFA Fitting for Tubing or Septum
- PFA fluoropolymer construction. Sample only comes into contact with high purity, inert fluoropolymer PFA, the ultimate in chemical resistance and non-contaminating material.
- Allows attachment of tubing or syringe sample extraction by switching caps.
- Compression ferrule secures tubing onto fitting with superior grip compared to metal fittings.
- Replaceable fluoropolymer-faced septum with large area allows repeated punctures with common lab syringes.
Nickel Plated Halkey® Roberts Barbed On/Off Valve
- Nickel Plated. Resists damage from most aggressive chemicals.
- Barbed stem for attaching tubing.
- Leak resistant seal prevents sample loss in closed position. However, when stem is not closed, sample air passes into ambient air outside valve.
