    Diffuser material between bulb and negative Durst 138

    Hi,

    what kind of diffuser material do you use between the bulb and the negative for the internal filter drawer on a Durst Laborator 138?

    Thanks for advice

    Either 1/16" white "milk" glass or 1/16" #2447 white plexiglass. You can also try a white diffusing gel filter on clear glass or on top of the bottom condenser. There is also a thread on replacement Durst bulbs, though they're mostly for 120 v The bulb you're using may be too small.

    Don't forget to use a blower for bulbs 250 W & larger. It's all explained in the manual, look at your other thread.
