Description
Laboratory bottle 50 ml GL 32 round without screw cap, brown tinted is a graduated laboratory vessel produced from DURAN® tubing in borosilicate glass 3.3. With a nominal volume of 50 ml, an outer diameter of 46 mm and a height of 87 mm, the round bottle features a GL 32 thread and permanent graduation markings that assist approximate volume reading during routine use. It is delivered without screw cap and without pouring ring, allowing free selection of matching closures and accessories. Brown tinting reduces light transmission and is therefore well suited to light-sensitive chemicals, reagents and samples. These laboratory bottles from manufacturer Witeg are intended for storage, dispensing and handling tasks in chemical, pharmaceutical and research laboratories. Borosilicate glass 3.3 provides the chemical durability and thermal stability expected of quality laboratory glassware. The 50 ml capacity is convenient for intermediate reagent volumes, sample preparation and general laboratory work that requires a graduated amber bottle with a GL 32 neck interface.
