Advantages:

• Wide volume range and fine digital display enable precise dispensing from as low as 0.01 mL up to nearly 1 liter, ensuring accuracy over diverse titration volumes
• 2.5 mL per turn dispensing increment balances ease of volume adjustment with precise control
• Low random and systematic measurement errors support reliable and reproducible titration results
• Mechanical operation and positive displacement system provide robust and pulse-free dispensing without electronic complexity
• Compatibility with multiple bottle threads via included adapters increases versatility across varied laboratory glassware
• Rotatable and variable discharge tube along with telescopic aspirating tube allow ergonomic adjustment to different containers and workspaces
• Long-life batteries with status indicator reduce interruptions and facilitate uninterrupted lab work
