SafeGrip Narrow Neck HDPE Plastic Bottle Series 310 – Leak-Proof Design

The SafeGrip Narrow Neck HDPE Plastic Bottle Series 310 is a compact, heavy-duty container designed for demanding liquid handling applications. Manufactured from robust high density polyethylene (HDPE), it offers excellent chemical resistance and impact strength in a small, easy-to-handle format, ideal where secure storage and leak prevention are essential.

Available in 50ml and 100ml capacities, this natural narrow neck bottle is supplied with a 32mm blue polypropylene (PP) screw closure featuring a PTFE insert and tamper evident ring. Together, the bottle and closure provide a reliable, leak-proof solution for laboratories, industrial sites, workshops and field sampling operations.

• Laboratory sampling and storage of reagents, standards and test solutions.
• Industrial process samples, oils, additives and chemical intermediates.
• Environmental and field sampling where secure, leak-proof transport is required.
• Quality control and R&D applications handling small-batch formulations.
• Storage of calibration solutions and high-value specialty liquids.

Frequently Asked Questions

Are these bottles suitable for use with aggressive chemicals and solvents?

The HDPE bottle and PTFE-lined PP closure offer excellent resistance to many chemicals, but compatibility depends on the specific substance and concentration. It is recommended to check chemical compatibility data for HDPE and PTFE with your product and, where necessary, carry out a small-scale test before full use.

Can the bottles be reused after cleaning?

The bottles are robust and can be reused if cleaned appropriately and if your processes allow reuse. Ensure that any previous contents are fully removed and that the bottle and closure materials are compatible with both the cleaning agents and the next product to be filled. For critical or sensitive applications, single use may be preferable.

How does the tamper evident ring work on the closure?

The closure is supplied with an intact tamper evident ring connected to the cap. When the cap is first unscrewed, the ring separates and remains on the bottle neck, providing a clear visual indication that the bottle has been opened since it was originally closed.
