Pall kroužek byl výrazně vylepšen na Raschig kroužku. Ačkoli vnější průměr kroužku je také roven jeho výšce, dvě řady oken s vnitřně se rozšiřujícím jazykem podobné kousky jsou řezány na prstencové stěně. Každá vrstva okenních otvorů má 5 jazykových kusů. Tato struktura zlepšuje distribuci plynu a kapaliny, plně využívá vnitřní povrch kroužku a zvyšuje účinnost distribuce a přenosu plynu a kapaliny. Je obecně vyrobena z kovu, plastu nebo keramiky. Molekulární síta mohou adsorbovat molekuly menší než jejich průměr pórů do pórů kanálů a odpuzovat velké molekuly mimo kanály, čímž hrají roli v screeningu molekul. Samozřejmě, molekulární síta mají nejen funkci screeningu, ale také mají určitou roli při zlepšování schopnosti reakce, to znamená, že působí jako médium v chemických reakcích na podporu pokroku chemických reakcí.
