Tubular vials are commonly used for the packaging of injectable medications and
vaccines. These vials are typically made of glass and come in various types and
sizes to meet specific pharmaceutical and healthcare needs. Here are some
common types of tubular vials used for injectables:
1. Clear Glass Vials: These are standard glass vials made from clear
borosilicate glass. They are used for a wide range of injectable medications,
including vaccines, antibiotics, and other pharmaceuticals. Clear glass vials
allow for easy visual inspection of the contents.
2. Amber Glass Vials: Amber or brown glass vials are designed to protect light-
sensitive medications and vaccines from degradation caused by exposure to
ultraviolet (UV) and visible light. These vials are commonly used for products
that are photosensitive, such as some antibiotics and biologics.
3. Colored Glass Vials: In addition to amber, glass vials can be found in other
colors to meet specific product branding or identification needs. Colored glass
can also provide additional protection against light.
4. Sterile Vials: These vials are pre-sterilized and often come with rubber
stoppers and aluminum caps to maintain sterility. They are commonly used for
aseptic filling of injectable medications.
5. Lyophilization (Freeze-Drying) Vials: These vials are specifically designed
for the lyophilization process, which involves freeze-drying of medications.
Lyophilization vials typically have thicker walls to withstand the stresses of
freeze-drying and reconstitution.
6. Screw Cap Vials: Some vials come with screw caps, which provide a secure
seal and are easy to open and close. These vials are suitable for various
7. Crimp Cap Vials: Vials with crimp caps require the use of a crimping tool to
create a secure seal. These vials are commonly used in pharmaceutical
manufacturing and are known for their tamper-evident closures.
8. Flip-Off Cap Vials: These vials feature flip-off caps that are designed to be
easily removed before use. Flip-off caps provide a visible indication of
whether the vial has been tampered with.
9. Customized Vials: Pharmaceutical companies often customize vials with
specific branding, labeling, and designs to differentiate their products in the
market. Customization can also include embossed or debossed logos and
other unique features.
10. Ready-to-Fill Vials: Some vials are supplied to pharmaceutical
manufacturers in a ready-to-fill state, including sterile vials that are pre-
cleaned and sealed. This simplifies the filling process for pharmaceutical
11. Small Volume Vials: For medications that require precise dosing in small
volumes, specialized small volume vials are available. These vials help
minimize waste and are commonly used for pediatric medications.
12. Large Volume Vials: Conversely, large volume vials are designed to hold
larger quantities of injectable medications or vaccines, often used for
institutional or mass vaccination purposes.
The choice of vial type depends on the specific needs of the pharmaceutical product,
including its stability requirements, light sensitivity, dosage volume, and branding
considerations. Pharmaceutical companies work closely with vial manufacturers to
select the most appropriate vial type for their injectable medications.
