Description
PE-LD narrow-mouth bottles with screw cap provide a nominal volume of 50 ml and a GL 18 thread for dependable sealing of laboratory liquids and reagents. Fabricated from low-density polyethylene, the containers combine chemical resistance, flexibility and impact strength, making them appropriate for everyday storage and transport of aqueous solutions, buffers or mild chemicals. The narrow-neck geometry enables precise pouring and minimises splash risk, while the integrated carrying handle facilitates safe handling of filled bottles. Offered as single pieces from manufacturer Hecht, these bottles suit chemical, sample-preparation and media-storage duties where lightweight, shatter-resistant plastic is advantageous. Translucent LDPE walls permit quick visual inspection of contents and fill level. The 50 ml capacity is convenient for intermediate aliquots, working stocks or small reagent batches. Together with the secure screw closure and ergonomic handle, the design supports organised bench and storage workflows, offering a practical balance of volume, durability and ease of use in research, quality-control and general laboratory environments.

What is this article?
Bottles of polyethylene, with screw cap narrow neck 50 ml GL 18 - size 5000 ml is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Plastic bottles (narrow & wide mouth), inside Bottles & containers, in Labware.
A plastic bottle is polyethylene, polypropylene or a fluoropolymer, narrow-mouth for pouring or wide-mouth for powders. It is the choice when the bottle must not shatter, and it is the wrong choice for solvents that swell the plastic.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
