These bottle-top dispensers offer convenience, high chemical resistance, and protection against contamination.

Dispensers are compatible with all high-purity concentrated acids, including hydrofluoric acid (HF), and are specifically designed to fit ARISTAR® ULTRA high-purity acid bottles

Precleaned dispensers are acid-cleaned pre- and post-assembly, and are assembled and packaged under ISO Class 5 (FED-STD-209E Class 100/M3.5) conditions.

The dispensers also fit ARISTAR® PLUS ammonium hydroxide and hydrofluoric acid bottles. They dispense reproducible volumes from 0.5–5.0mL. Each dispenser is calibrated and mechanically tested to ensure they meet volume, precision, and accuracy requirements. All wetted parts, including check valves and seals, are constructed of fluoropolymer PFA or TFM resin.
