Zátky
Netěsné, pevné zátky utěsňují lahve, baňky, lahvičky a dokonce i hadičky, aby zabránily úniku kapalin a plynů. Vícedírové varianty poskytují omezené stabilní podmínky proudění, které zabraňují hromadění vzduchových bublin. Díky mírně zúženému tvaru se zátky různých průměrů zasouvají do laboratorního skla pro těsné usazení, které přesto umožňuje snadné odstranění. Uzávěry jsou vyráběny z různých materiálů pro přesnou odolnost vůči agresivnímu obsahu a mohou udržovat vakuové prostředí.
