Tedlar Bag 5L With Innovative 2-In-1 Fitting
This 5-liter Tedlar bag is designed for atmospheric sampling with a patent-pending 2-in-1 fitting that combines a shut-off valve and a Teflon-lined septum. The stem accommodates 1/8” ID tubing for filling and sample removal. The bag uses 2 mil Tedlar PVF film and offers polypropylene fittings. It is Made in the USA and emphasizes a careful approach to sample integrity and contamination control. Guidelines recommend storing away from contamination sources and avoiding over-pressurization beyond 2 psi. Reuse is generally not advised for most sampling scenarios.
Use case considerations include environmental monitoring, VOC sampling, and gas concentration verification. When selecting for field work, consider the bag’s size and the availability of compatible tubing and spare fittings. Pack multiple bags if you anticipate repetitive sampling or long transport times, ensuring that materials in contact with samples are chemically compatible.
10L Tedlar Sample Bag Set (Dual Valves)
This bulk pack features 10-liter bags with dual polypropylene fitting valves for easy gas replacement and vapor testing. The 2 mil Dupont Tedlar PVF film provides robust barrier properties for many organic and inorganic gases. The dual valves streamline sample handling during field collection and subsequent laboratory analysis, reducing fill times and potential contact with ambient air during transfer.
Ideal applications include multi-sample campaigns, regulatory monitoring, and industrial hygiene assessments where larger sample volumes are beneficial. While the dual valves add convenience, ensure that compatible sorbents or analytical methods align with the bag’s materials and the target analytes. Always verify storage and transport conditions to minimize sample alteration between collection and analysis.
4L Tedlar Sample Bag Set (Dual Valves)
These 4-liter bags use 2 mil Dupont Tedlar PVF film and come with dual polypropylene fitting valves. They’re designed to support gas sampling and vapor testing across a range of contexts, balancing portability with capacity. The dual valves simplify sampling workflows by facilitating gas replacement without removing the bag from the sampling line.
Consider these for general field surveys where moderate sample volume is desired and analytical methods can accommodate the PVF film’s characteristics. As with all Tedlar bags, careful handling, appropriate tubing, and avoidance of over-pressurization help preserve sample integrity throughout transport and analysis.
1L Tedlar Sample Bag Set (Dual Valves)
The smallest option in this line, the 1-liter bags with dual fittings offer compact sampling for quick tests, spot checks, or pilot studies. The 2 mil Tedlar PVF film ensures a reliable barrier for many gases while the dual valves help with rapid collection and sample transfer. Packaging multiple units aids rapid deployment in dynamic environments where size matters.
Use this size when you need to maximize portability, such as in narrow field workspaces or rapid-response air quality tests. Pair these bags with a lightweight pump or manual filling method, and ensure all materials in contact with samples are compatible with the target analytes.
ESS GD1219-7000: Tedlar 10 L Sampling Bags
ESS GD1219-7000 bags come with a single combination valve that integrates an on/off valve and a septum port for added convenience. The bags feature solid seam construction and a corner opening with grommet for tagging or hanging, making them well-suited for transport and storage in field settings. The 10-liter capacity supports larger sample volumes without increasing bag size dramatically.
When evaluating this option, assess the requirement for easy tagging, storage, and robust seam strength. The combination valve design simplifies operations, but you should confirm that the material compatibility covers your specific gas targets and any potential sorbents used in subsequent analysis. As with allTedlar-based bags, avoiding over-pressurization remains essential to maintain bag integrity.
Buying Guide: Key Considerations For Tedlar Gas Sampling Bags
- Material and film thickness: Most options use 2 mil Tedlar PVF film, balancing durability with flexibility. Thicker films offer more puncture resistance but can be less flexible in tight spaces.
- Fitting design: Dual valves enable easy gas replacement and sampling, while 2-in-1 fittings simplify fill and sample removal in one connection. Choose based on workflow complexity and available lab equipment.
- Capacities and use cases: Smaller bags are highly portable for spot checks; larger bags support extended sampling campaigns and higher-volume analyses. Consider how often you need to fill and whether multiple samples will be analyzed.
- Contamination control: Store bags in clean environments away from potential contaminants. Ensure compatible tubing and septa materials align with your target analytes to avoid reactions or adsorption.
- Reusability and disposal: Tedlar bags are often designed for single-use in sampling to avoid cross-contamination. Consider storage and disposal protocols in your protocol.
- Storage and transport: Practice careful handling to minimize punctures. Ensure bags are not over-pressurized and that the maximum recommended pressure is observed during filling and transport.
- Compatibility with analysis: Confirm that your analytical method (gas chromatography, mass spectrometry, etc.) is compatible with the PVF film and fitting materials to prevent sample loss or alteration.
- Brand and warranties: Reputable brands typically provide guidelines, safety notes, and best-use practices. Review manufacturer instructions for best results and to maintain sample integrity.
Overall, selecting the right Tedlar bag depends on your sampling volume, field conditions, and downstream analysis. The five options highlighted here provide a spectrum of capacities and fittings to support a range of gas sampling scenarios—from compact, rapid checks to larger field campaigns with ease of handling and reliable containment.
