Efficient and comfortable SweFlex Saliva Ejectors actually reduce aerosols during treatment with superior suction capability. Anatomical "under-the-chin" design retracts tongue and stays put without hand support. Curved edge vent opening prevents tissue aspiration. Pre-shaped and flexible so one size fits all. Graduated 6 to 7mm connection end slips snugly into any saliva ejector valve for a tight fit — no adapters needed. Made in Sweden of aseptic white polyethylene. 100 tips per bag.
