The 6-position N-EVAP® nitrogen evaporator (cat. 11106) can concentrate up to six samples at the same time. It fits sample containers with outside diameters from 10 to 30 mm. For larger containers, there is an optional large sample holder that fits outside diameters from 30 to 56 mm. This makes the N-EVAP suitable for many types of sample tubes, vials, and small flasks.
The 6-position N-EVAP was developed in the early 1970s from the original 12-position model. It is known for being reliable, durable, and affordable. The instrument uses nitrogen gas and a heated water bath to safely concentrate samples. The circular rotating design allows all samples to face the front for easy loading and removal.
Each sample position has its own brass needle valve. These valves let you control the flow of nitrogen gas separately for each sample. This helps save nitrogen and prevents damage to sensitive samples. The water bath heats the samples gently, speeding up evaporation without overheating.
The stainless steel bath and high-quality materials make this instrument long-lasting. The 6-position N-EVAP is a practical choice for labs that need to concentrate different sizes of samples efficiently and safely.
