  • How can I finely control the vacuum applied by my vacuum pump or system?

    Some vacuum pumps or built in vacuum systems do not allow fine control over the vacuum applied. For rough work like vacuum filtration this is not always needed, but for more sensitive work, for example when using a rotary evaporator, application of the correct vacuum level is essential to smooth operation. The new ...
