How big is a 1 dram vial?

Answered by Jeremy Urbaniak

The 1 dram vial that I have measures 15 mm in outer diameter and has a length of 45 mm. To give you a better idea of its size, let me provide some context. A dram is a unit of volume commonly used in the pharmaceutical industry, and it is equivalent to 3.7 mL. So, this vial can hold up to 3.7 mL of liquid.

Now, let’s focus on its physical dimensions. The outer diameter of the vial is 15 mm, which is the measurement across the widest part of the vial. This diameter is relatively small, making the vial compact and easy to hold in your hand. It’s important to note that the outer diameter refers to the measurement of the vial’s outer surface, excluding any cap or closure that might be present.

Moving on to the length, the vial measures 45 mm. This measurement represents the height or vertical length of the vial. It is the distance from the bottom of the vial to the top, including any neck or lip that might be present. The length of 45 mm indicates that the vial is relatively tall compared to its width, giving it a slender appearance.

To further visualize the size of the vial, you can think of it as roughly the size of a small lipstick tube or a travel-sized perfume bottle. It’s compact enough to fit in the palm of your hand or in a small pouch, making it convenient for carrying around.

In terms of capacity, the 1 dram vial can hold up to 3.7 mL of liquid. This volume is often used for storing essential oils, fragrance samples, or other small quantities of liquids. It’s worth mentioning that the vial’s volume may not be filled to its maximum capacity, as some space at the top is often left to allow for proper sealing and to prevent spills.

The 1 dram vial with its dimensions of 15 mm outer diameter and 45 mm length is relatively small and compact. It can hold up to 3.7 mL of liquid, making it suitable for a variety of uses in the pharmaceutical, cosmetic, or fragrance industries.
