1. Basic parameters

Capacity range: 5ml, 10ml, 15ml, 20ml, 25ml, 30ml (common standard capacity, customizable)
Material
- PE (polyethylene):
- LDPE (low density, flexible and easy to squeeze)
- HDPE (high density, high hardness)
Bottle color: transparent/white/brown (light-proof requirement)
Drip tip material: medical grade PE or silicone, in line with USP Class VI biocompatibility standards
Sealing method: screw cap (with aluminum foil seal) or twist-type child-proof cap (CR Cap)

2. Physical properties

Temperature range: -20℃ ~ 60℃ (long-term storage); short-term resistance to 121℃ sterilization (such as HDPE material)
Sealing: no leakage when inverted (ASTM D4991 standard)
Drop resistance: no breakage when dropped from a height of 1.2m (in liquid state)
Moisture permeability: ≤0.5g/(m²·day) (to prevent moisture evaporation, ASTM E96 test)

3. Drip tip design (if applicable)

Drip volume control: about 25-50μl per drop (adjustable drip tip design requires tolerance ±10%)
Aperture: 0.3mm-0.7mm (adjusted according to the viscosity of the liquid)
Pollution prevention: The drip tip can be removed for cleaning or disposable (single pack)
