Vacuum Flash Assembly for DIY Vacuum Flash-Assisted Solution Process (VASP), Up to 5 mTorr - EQ-VFA-CVM-LD

Please email for lead time
Item Number: EQ-VFA-CVM-LD
EQ-VFA-CVM is a vacuum flash assembly for DIY Vacuum Flash-Assisted Solution Process (VASP). It is assembled with stainless steel vacuum components and a NIST traceable anti-corrosive digital vacuum gauge. With a mechanical vacuum pump (not included), the assembly can expose samples to a vacuum up to 5 mTorr in a flash for vacuum flash process. The vacuum pressure can be manually controlled by a needle valve connected to atmosphere or gas inlet.
