Pierścień palla został znacznie ulepszony na pierścieniu Raschiga. Chociaż zewnętrzna średnica pierścienia jest również równa jego wysokości, na ścianie pierścienia wycinane są dwa rzędy okien z rozciągającymi się do wewnątrz kawałkami przypominającymi język. Każda warstwa otworów okiennych ma 5 elementów przypominających język. Taka struktura poprawia dystrybucję gaz-ciecz, w pełni wykorzystuje wewnętrzną powierzchnię pierścienia i zwiększa wydajność dystrybucji i transmisji gaz-ciecz. Zwykle jest wykonany z metalu, plastiku lub ceramiki. Sita molekularne mogą adsorbować cząsteczki mniejsze niż ich średnice porów do kanałów porów i odpychać duże cząsteczki poza kanałami, odgrywając w ten sposób rolę w przesiewaniu cząsteczek. Oczywiście sita molekularne pełnią nie tylko funkcję przesiewania, ale również pełnią pewną rolę w poprawie zdolności reakcji, to znaczy działają jako "medium" w reakcjach chemicznych, promując postęp reakcji chemicznych.
