Rubber Pipette Filler, 3 Valves Lab Filler Bulb Red Suction for Industrial Mineral Agricultural

​​User Friendly Operation​​: The design facilitates straightforward liquid handling, allowing pipettes to draw solutions smoothly. The rubber bulb responds predictably to pressure adjustments, making it suitable for both novice and experienced users Material Composition​​: This pipette filler utilizes resilient rubber material that maintains flexibility and performance across various laboratory conditions. The construction supports repeated use in industrial and agricultural settings ​​Triple Valve Configuration​​: Three distinct openings leverage elastic rubber force to create controlled suction. This mechanism enables drawing of solutions into pipettes, enhancing measurement effect ​​Integrated Safety Design​​: A small ball within each rubber tube opening prevents solution intake into the bulb. Pressing the ball side forms controlled air gaps that regulate airflow, promoting secure liquid handling ​​Adjustable Liquid Control​​: The presence or absence of air gaps allows users to manage solution absorption. This feature supports customizable liquid transfer for experiments and industrial processes
