Beschreibung
Sample vials 4 ml with screw thread are amber borosilicate glass 3.3 containers for laboratory sample storage, preparation and transfer. Each vial offers a nominal volume of 4 ml and dimensions of 45 × 15 mm, giving a practical mid-size format between micro vials and larger bottles. The screw-thread neck is specified for N-13 caps, supporting a tight closure that helps reduce leakage and evaporative loss during handling and short-term storage. Amber (brown) glass limits light transmission, which is useful when working with photosensitive solutions, standards or extracts, while borosilicate glass 3.3 provides the chemical and thermal resistance expected of quality laboratory glassware. Available as a pack of 100 pieces from manufacturer Witeg, these vials serve analytical chemistry, environmental laboratories and related workflows that need dependable screw-cap vessels at the 4 ml scale. Geometry suits standard racks and boxes used with N-13 systems. Select compatible N-13 closures for your application and observe normal safe glassware practice throughout use and cleaning.
