All models are fitted with a new anti-drip safety valve, a feature which guards against drips when the Zippette is not in use. A fine adjustment mechanism allows for even greater reproducibility for repeat dispensing whilst the new right-angled delivery spout ensures accurate dispensing into narrow neck containers. Manufactured to ISO9002 quality system standards, each unit is supplied with an individual calibration certificate.
