Description
The 34 position N-EVAP combines flexibility with digital features for improved control over the evaporation process. This time-tested, durable system provides one of the least expensive prices per position of all the N-EVAPs.
The instrument comes with a side control box, which includes a pressure regulator, timer, and digital temperature controller. This allows the user to set an automatic gas flow cut off, which slows evaporation to a minimum once the timed cycle has been completed. In order to prevent damage to delicate samples, the timer also provides the option for the heat to shut off once the cycle is complete.
Like the rest of the N-EVAP line, the 34 position N-EVAP has an adjustable spring design to accommodate a range of sample tube sizes. Samples sit in a heated water bath under gentle nitrogen blowdown, leading to efficient sample concentration. The needles can be raised and lowered individually, while needle valves allow precise adjustment of the gas flow rate at each sample position. This promotes efficient and safe sample reduction with minimal nitrogen waste.
Advantages:
- Precise: Digital controls allow precise temperature regulation
- Flexible: An adjustable sample holder design fits a wide variety of sample sizes at once
- Gentle: N-EVAP nitrogen evaporators combine nitrogen blow down with a heated bath to gently concentrate delicate samples
- Individualized Control: Gas flow can be controlled at each sample position via needle valves
Unheated, acid resistant, and Teflon free models for PFAS analysis are also available.
