DURAN® Screw cap, GLS 80, PSU Compund, with PTFE / silicone seal, for DURAN® laboratory bottles

DURAN® GLS 80® high-temperature screw cap, PSU, white, wide neck, with PTFE-coated, platinum-cured silicone sealing washer White GLS 80® wide-neck screw cap made of PSU (cap seal). The material used is a special composition based on a polyarylsulfone. As a result, the chemical, thermal and mechanical properties of the material have been significantly improved and adapted to laboratory requirements. The PTFE seal coated on both sides (sealing washer: platinum-crosslinked silicone) allows the bottle to be sealed tightly. A matching PTFE pouring ring is available and allows clean, drip-free working. Special features and benefits: PSU caps and the ETFE pouring rings provide higher thermal and chemical resistance than comparable polypropylene components The additional 30% glass fiber reinforcement of the PBT resin improves stiffness, tensile strength and impact resistance of the screw cap The screw cap seal with PTFE-coated cap septum provides an efficient seal The matching pouring ring made of ETFE allows drip-free removal and clean, safe working Application: Autoclaving of media and reagents, preparation of media and reagents, sampling, culture vessel, storage of media and reagents, transport and shipping
