The reagent bottle has two choices of narrow mouth and wide mouth. The capacity is 60ml/125ml/250ml/500ml/1000ml. And the colors are transparent and brown. The transparent bottle body can clearly see the contents of the storage. The brown color is protected from light and can prevent ultraviolet rays. We also support small orders with a MOQ of 1 carton. Of course, the higher the quantity ordered, the better the price.
