The GLS 80^® quick release thread allows opening and closing of bottles with three-quarters of a turn. This closure contains dyestuffs. There is a lower risk of contamination due to the double-sided PTFE-coated silicone seal. The medium only comes in contact with PTFE. The matching pouring ring made of PTFE allows clean, drip-free working. Please order separately.
