For brands and laboratories prioritizing ease of access and efficient dispensing, our standard 20-400 glass dropper provides a seamless user experience. Unlike child-resistant versions, this non-CRC closure allows for quick, effortless opening—making it ideal for daily-use skincare routines or fast-paced professional lab environments. The ribbed cap design ensures a non-slip grip, even when handling oily substances, while the precision-tapered glass pipette minimizes residue and ensures precise dosage every time.
We understand that consistency is key in large-scale procurement. Our droppers feature chemical-resistant glass and inert rubber components that maintain the purity of your formulas, preventing contamination or degradation. The 20-400 thread is strictly manufactured to international standards, ensuring a leak-proof seal with standard 1oz Boston Round or Euro bottles.
