VeriAir Flex® Tedlar® Sampling Bags

Key features:

• Referenced in many EPA methods (e.g. T015)
• Quality DuPont Tedlar® film for sample integrity and valid data
• Good stability for CO, CO2, CH4, SF6, VOC and complex organic mixtures
• Not recommended for H2 or He
• Polypropylene valve for economy and light weight
• Two sizes available: 1 liter and 4 liter
• Valve is comprised of polypropylene

VeriAir Flex® manual-inflating bags feature a patented design that allows users to directly collect air or gas samples without any need for an external pump or other sampling equipment. The VeriAir Flex® bag uses a patented integrated handle design that can be used for both filling the sample bag and removing or flushing a gas sample from the bag. 

VeriAir Flex® Foil Sampling Bags

Key features:

• More durable and less susceptible to damage during shipment in an unpressurized airplane cargo hold
• Light/moisture proof – protects light-sensitive compounds
• Low VOC and sulfur backgrounds
• Good storage stability for low ppm & high ppb level VOCs
• Good stability for low molecular weight compounds such as CO, CO2, CH4, SF6
• Good 48-hr. stability for H2S, H2, COS, CH4S, C2H6S
• Two sizes available: 1 liter and 5 liter 
• Nickel-plated brass valve

The VeriAir Flex® foil sample bags are available with either the economical nickel coated brass valve or the more inert and less reactive aluminum valve. The aluminum valve configuration has been shown to keep your samples stable for longer hold times, even those samples that contain sulfur compounds such as H₂S and mercaptans. Both types of polyolefin/aluminum valve on the VeriAir Flex® sample bags are proven to be durable enough to maintain their integrity, even if exposed to extreme atmospheric pressure drops and are therefore ideal for overnight air shipment for rush analysis.
