Brown narrow mouth bottle

The brown color of the bottle provides protection against light and UV radiation, making it ideal for storing light-sensitive substances such as medications, essential oils, and chemicals. The dark glass helps to block out harmful UV rays, preventing degradation and maintaining the integrity of the contents. The narrow neck and small opening of the bottle allow for controlled pouring and precise dispensing of liquids. This is particularly useful in laboratory settings for accurate measurement and transfer of reagents or solutions. 

Furthermore, the tight seal provided by the narrow opening helps to prevent contamination and maintain the freshness and potency of the stored substances.

棕色的瓶身可防止光線和紫外線輻射，非常適合儲存對光線敏感的物質，如藥物、精油和化學品。深色玻璃有助於阻擋有害的紫外線，防止降解並保持內容物的完整性。瓶頸窄、開口小，便於控制液體的傾倒和精確分配。這在實驗室準確測量和轉移試劑或溶液時尤其有用。

此外，窄口瓶提供的嚴密密封有助於防止污染，保持所儲存物質的新鮮度和有效性。
