DGU-20A On-line Degassing Unit
The DGU-20A3/20A5 is an on-line degassing unit that uses fluoroethylene membrane. The internal capacity is only 1/25th of previous models, and waiting time at mobile phase replacement or stabilization can be significantly reduced.
DGU-10B Helium Degassing Unit
This can degas up to four mobile-phase solutions by helium bubbling.
Note: Using helium for degassing provides higher degassing capacity than degassing unit that use a membrane, but operating them requires more care.
