Medical Grade Zirconia Ceramic Plunger
Biocompatibility is the most prominent advantage of this zirconia ceramic plunger. The material is non-toxic, non-allergenic and completely harmless to human tissues and body fluids, complying with international medical safety specifications. It will not produce chemical reactions or precipitate harmful substances when contacting medical reagents, infusion solutions and biological liquids, effectively avoiding secondary pollution and ensuring the safety and purity of medical fluid transmission, which is irreplaceable in sterile medical scenarios.
In terms of structural performance, the zirconia plunger features ultra-high hardness, excellent wear resistance and low friction coefficient. Its super smooth surface effectively reduces friction loss during reciprocating operation, ensuring stable and precise dosing and injection accuracy for a long time. With outstanding mechanical toughness and pressure resistance, it resists cracking and deformation under high-frequency continuous operation and high-pressure working conditions, maintaining consistent dimensional stability and operational precision.
Additionally, the product possesses excellent corrosion resistance against medical alcohol, disinfectants and various pharmaceutical liquids, with no aging or deterioration after long-term repeated disinfection. It is widely used in medical syringe pumps, infusion pumps, diagnostic testing instruments and pharmaceutical precision filling equipment. With strict medical-grade quality control, stable batch performance and ultra-long service life, our zirconia ceramic plungers greatly reduce equipment maintenance frequency and clinical application risks, providing high-precision, safe and durable solutions for modern medical precision fluid control.
