Pallringen har förbättrats avsevärt på Raschig-ringen. Även om ringens yttre diameter också är lika med dess höjd, skärs två rader av fönster med inåtsträckta tungliknande bitar på ringväggen. Varje lager av fönsterhål har 5 tungliknande bitar. Denna struktur förbättrar gas-vätskefördelningen, utnyttjar ringens inre yta till fullo och förbättrar effektiviteten i gas-vätskefördelning och -överföring. Den är i allmänhet gjord av metall, plast eller keramik. Molekylsiktar kan adsorbera molekyler som är mindre än deras pordiametrar i porkanalerna och avvisa stora molekyler utanför kanalerna och därmed spela en roll i screeningmolekyler. Naturligtvis har molekylsiktar inte bara funktionen av screening utan har också en viss roll för att förbättra reaktionsförmågan, det vill säga de fungerar som ett "medium" i kemiska reaktioner för att främja utvecklingen av kemiska reaktioner.
