Bacteria and other microorganisms that are found in almost all process mediums can lead to the formation of biofilm. This can have an extreme negative impact on plant operations. Biofilm formation can threaten financial well-being and have environmental and health & safety implications.
Pacific Sensor offers this Biofilm Coupon to monitor the biofilm formation in your systems. Constructed from a Nickel/Chrome mesh, this coupon provides an ideal surface for biofilm growth while resisting corrosion. The material collected can be cultured to help better quantify and identify what issues my be effecting your system.
Our Biofilm Coupon is manufactured to the same size as our common weight-loss corrosion coupons. This allows it to be mounted using our standard coupon holders.

Pack of 10 heater tubes for ASTM D3241.
Metaspec manufactures heater tubes that fully satisfy the requirements of ASTM D3241, the Jet Fuel Thermal Oxidation Stability Test. Metaspec heater tubes are listed in ASTM D3241-25a. This test is designed to create deposits on the heater tube if there are certain types of impurities in the jet fuel. The fuel quality is rated visually by comparing the heater tube with a standard color chart under 3x magnification or using a digital tube rater that measures deposit thickness.
Metaspec heater tubes are manufactured from 6061 aluminum and polished using a proprietary technique which produces a highly consistent mechanical surface finish. This makes it easy for operators to rate the tubes either visually or using digital tube raters. Thousands of tests have been conducted at laboratories around the world and have established that Metaspec tubes provide statistically equivalent results to other brands whether rated visually or digitally.
Heater tubes are sold in a pack of ten. Each heater tube is carefully cleaned, inspected, serial-numbered, and ready for use in the laboratory.
JFTOT is a registered trademark of Petroleum Analyzer Company, L.P. (PAC). It is also a generic acronym for the ASTM D3241 "Jet Fuel Thermal Oxidation Test". Neither Metaspec nor Pacific Sensor is affiliated with PAC.
