The 6 position N-EVAP’s ability to expand the sample size range with an optional large sample holder makes it an ideal instrument for laboratories that will be evaporating up to 6 samples at once and are using a wide range of sample flask outside diameters. The standard instrument fits samples with an outside diameter of 10-30 mm, and the optional large sample holder can accommodate samples with an outside diameter of 30-56 mm.The 6 position N-EVAP sample concentrator (cat# 11106) was adapted from the 12 position N-EVAP (cat# 11155) in the early 1970s. Since its inception, it has proven to be durable, reliable, and the most affordable member of Organomation’s N-EVAP line. These economical units provide controlled concentration of sample vials through the application of nitrogen gas within a heated water bath.
