Product Description
I. Overview
The plastic dropping bottle is an essential tool for precision liquid dispensing and micro-sampling in the laboratory. Manufactured from low-density polyethylene (LDPE) through precision blow molding, offering flexibility, durability, and lightweight construction.
The integrated dropper tip design is the key feature — the tip is molded as a single piece with the bottle body, eliminating seams and leak risks. Squeezing the bottle body controls drop speed and volume with precision. Equipped with a PP leak-proof cap for secure reagent storage.
Available in natural (translucent) and white colors. The white bottle contains UV-blocking agents to protect light-sensitive samples such as photo-sensitive reagents and biochemical diagnostics. Capacities range from 3ml to 125ml, suitable for precision titration, micro-sampling, reagent dispensing, and more.
🔬 Color Selection:
Natural (Translucent) — Allows easy viewing of liquid level and remaining volume — suitable for routine reagents.
White — UV-blocking protection for light-sensitive samples (vitamins, antibiotics, fluorescent reagents, etc.).
