NEUBERG Dispenser
The N type has three models due to differences in specifications: - NP type Uses a single-acting cylinder in the drive section and is particularly suitable for high-viscosity liquids. In addition to the standard non-sealed type, there is also a sealed type. - ND type Uses a double-acting cylinder in the drive section and allows for discharge speed control via a speed controller. - NZ type Uses a stacked piezoelectric element and a displacement amplification mechanism for valve opening and closing control, allowing for a wide range of settings from low to high speeds. Operation settings such as discharge volume, discharge speed, and continuous operation count can be configured using a computer, enabling remote settings.

basic information
The NEUBERG dispenser type N is a compact and lightweight non-seal liquid dispenser developed for discharge accuracy and long-term stability. It exhibits its characteristics in fields where precise management of each drop is required, ranging from low-viscosity to high-viscosity liquids, due to its minimal dead space. 【Operation Description】 ■ Type N consists of a rod-shaped needle valve that functions as an outlet valve at the center, a pipe-shaped measuring plunger surrounding it, and a pipe-shaped inlet valve surrounding that. ■ Each valve operates as shown in the diagram below, closing the needle valve, opening the inlet valve, and raising the measuring plunger to a predetermined amount to create a state of liquid suction as the origin point. ■ Upon receiving a start signal, the inlet valve closes, the needle valve opens, and the measuring plunger pushes out the liquid. ■ After discharge, the needle valve closes, and the inlet valve opens to return to the suction operation.

Applications/Examples of results
This is a non-seal liquid dispensing system that can handle a wide range of viscosities, from low-viscosity liquids such as pharmaceutical solutions and electrolytes to high-viscosity liquids like epoxy and silver paste, and dispenses one drop at a time in a timed process. *For more details, please contact us.*
Company information
The NEUBERG dispenser is widely used in fields that require strict discharge quantity management, equipped with balances and other measuring instruments on the manufacturing line, and allows for setting tolerance ranges. It is designed as a micro-dispenser with a discharge volume of 0.05 µL or more and 0.1 mL or less, with a focus on precision, aiming to maintain that precision over a long period. We offer six types suitable for various applications: N, L, R, K, T, and V. Although the structures of each type differ, they are characterized by a volumetric measurement system equipped with a forced valve for precise micro-dispensing. → For product details, please refer to the product page or contact us.
