Spot dropper with thickened red rubber head, silicone red skin head, laboratory dropper bottle, dropper cap

Core Features

Thickened design: thicker than ordinary rubber heads on the market, with improved sealing and durability, and greater suction during compression.

High compatibility: Suitable for various laboratory vessels such as droppers, droppers, straws, and micro blood collection tubes.

Corrosion resistance: Silicone material can resist common solvent erosion and reduce aging deformation.

Usage scenarios

Laboratory operation: precise pipetting, reagent dripping (need to be suspended vertically 0.5cm above the container).

Medical/Industrial: Medical droppers, liquid transfer in chemical experiments.

Precautions for use and maintenance

Avoid inverted or flat tabletop, clean and air dry after use to prevent adhesion.

Latex heads are prone to hardening after long-term exposure and can be softened by soaking in diluted hydrochloric acid (handle with caution).
