The Tarsons Masterpense Bottle Top Dispenser (051190) represents the next generation of precision fluid handling technology. Engineered for the most demanding laboratory environments, this instrument provides a seamless solution for dispensing measured volumes of aggressive reagents, organic solvents, and concentrated acids directly from the reservoir bottle. What sets the Masterpense series apart is its superior piston-cylinder system, which utilizes high-purity ceramic or PTFE components to ensure zero leaching and maximum chemical resistance. This dispenser is designed to eliminate the common issues of "piston freezing" and physical strain, offering an ultra-smooth plunger movement that allows for effortless repetitive pipetting over long shifts.
With the 051190 model, Tarsons has focused on safety and accuracy. The integrated recirculation valve prevents reagent waste by channeling excess fluid back into the bottle during priming. Its volume adjustment mechanism is designed to be highly intuitive, featuring a locking nut to prevent accidental volume shifts during high-speed operations. Whether you are performing routine sample preparation or complex chemical synthesis, the Masterpense ensures that every drop is accounted for with professional-grade precision.
