Description
Steep-shoulder bottles 50 ml with narrow neck and PE stopper are clear soda-lime glass laboratory bottles equipped with a standardised ground joint NS 14/15. These compact Enghals steep-shoulder bottles are intended for small-volume storage, sample aliquots and routine liquid handling where contents must remain visible. Clear glass and the steep-shoulder form support stable placement on the bench and straightforward transfer into or out of the vessel. A polyethylene (PE) stopper fits the NS 14/15 joint, providing a reliable interchangeable closure for many everyday laboratory solutions. Each bottle offers a nominal volume of 0,05 l and a net weight of 0,064 kg, making the size practical for limited sample quantities and space-conscious setups. Available in packs of 10 pieces from manufacturer Witeg, they match common ground-joint systems used in teaching, quality control and research laboratories. Narrow-neck construction helps reduce evaporation and spillage compared with wider openings. The combination of soda-lime glass, clear finish, PE stopper and NS 14/15 joint supports standard workflows without requiring specialised glass types or additional coatings.

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.
