Narrow-Neck Graduated LDPE Bottle with PP Cap, LDPE Stopper and Tamper-Evident Sealing Rings

Round narrow-neck bottle in low-density polyethylene (LDPE). Printed body graduations for quick visual volume check. Closed with a polypropylene screw cap and integrated LDPE stopper.

Features

• Bottle material: LDPE (low-density polyethylene)
• Cap: PP (polypropylene) screw closure
• Stopper: LDPE, leak-tight seal
• Neck: Narrow
• Graduations: Printed on bottle body
• Tamper evidence: Sealing rings on body and cap for tamper-evident tie

Applications

Storage and transport of aqueous reagents, dilute acids, bases and buffer solutions. The tamper-evident ring system makes these bottles suitable for samples requiring opening traceability — QC reference samples, inter-laboratory shipments and chain-of-custody protocols.

The narrow neck allows controlled pouring and reduces spill risk. Routinely used in analytical, pharmaceutical, environmental and process-control laboratories.

Why LDPE

Flexible under pressure — will not crack if contents expand. Translucent body allows level inspection without opening. Resistant to most common laboratory chemicals. Lighter than glass with no breakage risk in transit.

Tamper-Evident System

Rings on the bottle body and cap accept a standard plastic or metal security tie. Once sealed, any opening is immediately visible. A straightforward solution where protocols require documented container integrity.
