Sample Vials
Tubes and vials for general collection, storage, and transportation of samples; available in a variety of colors, sizes, volume capacities, and material compositions; may be sterile, non-sterile, and/or autoclavable; may include caps.
The term “vial” is somewhat undefined and is usually described as a small, cylindrical, and flat-bottomed container used to hold liquids. Most sample vials are made of plastic or glass, and include a separate or attached lid or closure. Sample vials are categorized by material and also by their size or specific purpose.
Glass sample vials are categorized by the type of glass used to make them.
- Type I, Class A glass sample vials are made from low-expansion borosilicate glass
- Type I, Class B glass sample vials are made from an alumino-borosilicate glass
- Type II are made from soda-lime glass
Plastic sample vials may be made from a variety of resins, including:
- Polycarbonate
- Polypropylene
- Polystyrene
- Low-density polyethylene (LDPE)
- High-density polyethylene (HDPE)
Glass sample vials may be clear or amber-colored (to protect the contents from ultraviolet light). Plastic sample vials are available in a range of colors, including amber, natural, and clear resins.
Sample vials may have different types of closures, depending on their use and the material being stored.
- Screw caps
- For both glass and plastic sample vials
- May be closed or open
- Typically made from polypropylene or phenolic resin (with a variety of closure liners, including PE foam, PTFE, cork, tin, etc.)
- Flip-top
- Caps for plastic sample vials may be attached by a tether to the vial itself
- Also called “captive” closures
- Snap caps (external): Both glass and plastic sample vials
- Plug caps (internal): Both glass and plastic sample vials

MEDILUMINE INC MediLumine Inc. Vascupaint™ clear kit with one bottle of clear silicone (200 ml), one bottle of diluent (200 ml), and one bottle of catalyst (20 ml)
Vascupaint™ Clear is a lead-free, silicone-based injection compound specifically engineered for researchers requiring bespoke imaging solutions. This formulation allows for the seamless integration of user-defined, oil-soluble fluorescent dyes, providing total control over excitation and emission profiles for complex vascular mapping. Designed with a lower viscosity than traditional lead-based media, it ensures effortless perfusion of microvasculature in both non-surviving organisms and human organs for ex vivo 3D analysis. Following alcohol-based tissue clearing, Vascupaint™ Clear provides a highly transparent matrix, ideal for high-resolution 3D imaging using fluorescence or brightfield microscopy.
