1. Large capacity design The 0 25 ml capacity range is available to ensure a safe, smooth and accurate dispensing experience with the bottle dispenser. It is suitable for most laboratory reagent bottles to meet the experimental needs of different users. 2. Adopts a double valve design to prevent waste and dripping, with a small operating force and easy plunger movement. When the dispenser is not used for a short period, the discharge pipe protective cover helps prevent leakage. 3. Professional Used for quantitative droplet measurement, it can accurately add droplets to containers for volume analysis, titration, dilution and other experimental operations. An instrument used for routine chemical analysis operations in the laboratory. Very convenient. 4. Wide application Suitable for hydrofluoric acid, strong acid, fuming acid, alkali, solvent and extremely dangerous liquids. Resistant to most acids, alkalis, organic solvents, organic and inorganic liquids; avoids the smell of fuming acid and foul smelling chemical liquids. Use scenarios Volume analysis and titration: use the dispenser to add precise droplets to a reaction or analysis vessel to achieve accurate volumes during standard chemical analyses. Dilution and sampling: perform small, controlled additions when preparing dilution series or sampling from reagent bottles for routine experiments. Handling hazardous reagents: work with reactive or dangerous liquids with confidence, taking advantage of the dispenser's compatibility and leak prevention features for safer dispensing.
