- Large capacity and adjustable range: 0-25 ml capacity range provides a safe, smooth, and accurate dispensing experience with the bottle-top dispenser. It is compatible with most laboratory reagent bottles to meet the experimental needs of different users. - High quality construction: double return valve design prevents waste and dripping, with a low operating force and easy plunger movement. When the dispenser is not used for a short period, the discharge pipe protective cover prevents leakage. - Professional precision: designed for quantitative droplet measurement, enabling accurate delivery of droplets to containers for volume analysis, titration, dilution, and other experimental operations. An instrument suitable for routine chemical analysis in the laboratory. - Wide application and safety: suitable for hydrofluoric acid, strong acids, fuming acids, alkalis, solvents, and extremely dangerous liquids; resistant to most acids, alkalis, organic solvents, and inorganic substances. Helps minimize odors from fuming acids and foul-smelling liquids. Practical use scenarios - Use in volume analysis and titration: dispense precise droplets to analyze concentration and perform titration with controlled droplet delivery. - Use in dilution and sample preparation: create accurate dilution series by adding exact droplet volumes to achieve target concentrations. - Safe handling of hazardous liquids: dispense hazardous reagents such as strong acids or HF with reduced risk of leaks, thanks to the protective discharge cover and secure valve design.
