The SDI Diagnostics Spirotubes (Type A Bulk Configuration) are premium, single-use cardboard mouthpieces designed for standard pulmonary function testing, spirometry screenings, and peak flow monitoring. Engineered with precision-cut, smooth edges to maximize patient comfort and eliminate tissue irritation, these disposable tubes provide a clean, secure lip seal during forced expiratory maneuvers. The structural design features an optimized wall thickness with an approximate 28 mm inner diameter and 30 mm (1 3/16 inch) outer diameter that resists bending or collapsing under firm teeth clenching, ensuring an unrestricted airway for highly accurate flow and volume measurements. These mouthpieces serve as a cost-effective, hygienic barrier that protects the internal sensor mechanics of the testing device from heavy moisture accumulation, while completely eliminating the time-consuming sterilization procedures required for reusable parts between patient appointments. This specific product code designates the bulk packaging configuration, supplying a master case of 2,000 total spirotubes organized internally as 20 convenient dispenser bags containing 100 pieces each.
