Ai UL/CSA -40°C 316L SST 4.6L Capacity Cold Trap w/ KF25 Ports


Categories: , SKU: T40x-UL


The new Ai 3rd Gen -40°C/F T40 cold traps all come ETL certified, standard. They have a small footprint, but at the same time, offering you the same cooling power. New features include a large 316L SST 4.6 liter trap, 316L corrosion-resistant trapping layers and vacuum connections, PTFE encapsulated silicone sealing gasket, upward KF25 vacuum connections provide you safer and easier vacuum tubing connection and removal. No chilling fluid required, just plug and play.

Grade 316, also called “The Food Grade Stainless” or “Marine Grade Stainless”, is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.

Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures. 316L are used to avoid corrosion problems caused by welding. Stainless steel valves and cylinders manufactured in 316L grade stainless steel have proved to offer exceptional resistance in acidic and hard water areas.

316L grade has the following adventage compare to regular 304 grade SST:

  • Extremely stains, corrosion, oxidation and pitting resistant
  • Considerably more resistant to humidity, chlorine, sulfuric acid, chlorides, bromides, iodides and fatty acids
  • Excellent formability
  • Easier to clean
  • Rupture and tensile strength at high temperatures
  • Excellent toughness and pressure performance at cryogenic temperatures
  • 316L stainless steels (containing molybdenum) are required in the manufacture of certain pharmaceutical, medical, surgical or chemical equipment in order to avoid excessive metallic contamination
  • Longer equipment life expectancy
