We have Canister sizes for all your needs

Entech’s SiloniteTM (SiloniteTM VS Summa) canisters feature a large volume capacity for detection of volatile chemicals down to the low part per trillion range. An inert and durable internal SiloniteTM coating provides a high-quality, long-term sample storage solution. Losses in the valve are avoided by using our new TrueSeal ValveTM which includes Entech’s new double-seal technology and low carryover, replaceable nickel ferrules. An integrated valve guard is securely welded to the canister for superior light-weight valve protection without any stresses to the valve stem associated with heavy “strapped-type” valve guards. These canisters are certified to meet or exceed the technical specifications required for EPA methods TO-14a and TO-15. High-quality performance is verified for EVERY canister with our demanding chemical inertness tests.

The Silonite™ Advantage

Silonite™ Coated

100% inertness tested prior to shipment. Polished internal surface prior to Silonite™ coating for the most inert surface possible.

Silonite™ ensures there is no chance for corrosion and the subsequent loss of reactive compounds.

Silonite™ canisters are the only inertness-repairable canisters on the market. No need to fear canister inertness testing. Entech’s renewal process can return old Silonite™ cans to better than new conditions.

Externally electro-polished “after” Silonite™ coating to provide a more analytical and professional look.

Uncoated Canister

Rapidly lose their ability to recover important VOCs such as Carbon Tetrachloride. During the manufacturing of 6L half shells, organic contaminants in the form of grease and oils become trapped in the surface pores found in all stainless steel sheet metal.

Interior will easily corrode.

The metal oxides found in SUMMA canisters can actually be catalytic in promoting certain chemical reactions.

Because of the limited inertness of the SUMMA canister, a certain amount of water vapor is actually needed to allow Air Toxic compounds to remain stable. Even aromatic hydrocarbons can be lost to the surface of a SUMMA canister if enough water isn’t present.

MiniCansTM are the next generation of air sampling canisters from Entech. Designed for tool-free operation and advanced robotic analyzers, Silonite® treated MiniCans™ allow the recovery of a wider range of compounds than any other sampling canister – including semi-volatiles up through the full diesel range and C25hydrocarbons.
