Nalophan Bags:

Nalophan is an inexpensive material used for making disposable sampling bags. Nalophan can be purchased pre-made, or as a large roll to reduce cost. Nalophan provides a cost-effective solution, but has the shortest holding time for most compounds such as H2S, Ammonia and VOCs.

Tedlar Bags:

Tedlar has been the standard in air sampling for 20 years now. Tedlar bags will provide a reusable storage medium with good retention for most substances. Scentroid Tedlar bags are made of 2mm thick film and purged at 100 °C using Scentroid’s patented heat/vacuum SP20 Purger. Sampling bags are pressure tested and leak tested to ensure the utmost perfect quality.

PTFE Bags:

Scentroid is the only manufacturer offering PTFE sampling bags. These bags have a much higher resistance to contamination and Scentroid’s PTFE Sampling Bags have a longer holding time than Tedlar bags. They are also the only accepted bag material for all standards. PTFE Sampling bags are extremely resistant to contamination and therefore can be easily cleaned and reused. They have been approved by the Ministry of the Environment in Ontario and almost every other jurisdiction around the world.

Stainless Steel Bags:

Scentroid is the only manufacturer in the world to offer stainless steel sampling bags. Each stainless steel bag is made of electro-polished marine grade (316L series) stainless steel film. Stainless steel sampling bags are ideal for sampling corrosive materials such as high H2S or benzene. Stainless steel is rolled into a thin film that provides flexibility while maintaining 100% sample preservation. Scentroid’s stainless steel bags are used more often than SUMMA canisters.

Scentroid Sampling Bag Fittings:

Scentroid sample bag fittings are designed specifically for air sampling. Scentroid fittings are offered in a choice of materials and styles to fit a variety of applications. Stainless steel, polypropylene, and PTFE fittings combine the connector and valve with septum into one easy to use fitting. Compression style fittings made of PTFE coated nylon are used on larger bags where low flow restriction is required.

2 in 1 Polypropylene

On/Off valve function with replaceable septum in a single unit. Quick, easy opening and closing of valve. Less than one half turn opens/closes the valve. These fittings fit 4/1” & 6 mm tubing

2 IN 1 PTFE FITTING

The combination fitting and septum is made of pure PTFE and offers high corrosion resistance. The fittings are light weight and therefore provide an excellent choice for PTFE sample bags

PTFE COATED NYLON

These fitting offer zero resistance with sample flow and therefore are the ideal choice for large sample bags. They also allow attaching tubing or syringe sample extraction by changing caps

STAINLESS STEEL FITTING

These all stainless steel fittings are used only on Scentroid stainless bags. This type of fitting is highly resistant to corrosive materials and can be used in high temperature sampling
