This firm has developed a PFA version of its Deep Flow sampling system (photo) as an economical alternative to corrosion-resistant metals such as titanium, tantalum or alloys. Deep Flow uses a magneto-pneumatic drive to circulate the product to be analyzed out of the reactor into a sampling valve, and then the sample is returned to the reactor by means of gravity. The absence of pumps reduces material and maintenance costs. Deep Flow operates over the temperature range from – 40 to 180°C. Hall 8, Stand L1A — Biar S.A., Lourtier, Switzerland
