• 【Lab Liquid Bottle Top Dispenser】: Used for quantitative droplet measurement, can accurately add droplets to containers for volume analysis, titration, dilution and other experimental operations. Instruments used for routine chemical analysis operations in the laboratory. Very convenient. (without bottle)
• 【4 Capacity Optional】: 0.5-5ml, 1.0-10ml, 2.5-25ml, 5.0-50ml capacity ranges are available to ensure a safe, smooth and accurate dispensing experience with bottle dispensers. Suitable for most laboratory reagent bottles to meet the experimental needs of different users.
• 【Precise Volume Setting】: Precise scale design, smooth and precise piston sliding up and down, making operation convenient and comfortable, and 5 types of bottle adapters are provided, suitable for most laboratory reagent bottles. The design of the back-flow valve reduces the waste of reagents and dripping。
• 【Premium Material】: Made of PTFE, FEP, BSG, PP and other materials, with a maximum pressure resistance of 500mbar, a maximum viscosity resistance of 500mm²/s, and a maximum liquid temperature resistance of 40°C. The mouth joint is airtight and does not leak liquid.
• 【Widely Used】: The absence of spring in the valve and the use of inert materials ensures high chemical compatibility with a wide range of acids, bases, solvents, organics, and inorganic. Safety cap for discharge pipe, which can avoid contact with reagents and can be easily installed or removed even with gloves.
