Vertex® RV Bottle Top Dispenser is yet another innovation born from RV Instruments’ strong R&D foundation. Responding to the evolving needs of modern laboratories, RV Instruments proudly introduces its new-generation Bottle Top Dispensers in two indigenous versions – Regular and Premium – offering a unique combination of affordable pricing and high performance.
The Premium Model, equipped with a re-circulation valve, allows for the easy priming of the dispenser without any loss of valuable reagents. All wetted parts are made from PTFE, FEP, and Borosilicate Glass, ensuring excellent chemical resistance and compatibility with most laboratory reagents (excluding hydrofluoric acid).
A simple yet robust design, paired with a variety of user-focused features, makes the Vertex® Bottle Top Dispenser the ideal choice for all liquid dispensing requirements. High precision and accuracy are achieved through the careful selection of premium raw materials and multiple stages of stringent quality control during manufacturing. Each instrument is individually calibrated in compliance with ISO 8655 standards and supplied with a factory calibration certificate to ensure reliable performance.
