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
Alkali Scientific CryoFreeze™ 12 Place Cell Freezing Container for 5mL Cyrovials, –1°C/min Cooling, 1/Pk
The Alkali Scientific CryoFreeze™ 12 Place Cell Freezing Container is optimized for controlled rate freezing of samples stored in 5 mL cryogenic vials. When placed in a –80 °C freezer, the system provides an alcohol free cooling rate of approximately –1 °C per minute, supporting reliable cryopreservation of a wide range of cell types and cell lines. Constructed with high density polyethylene foam and an alloy based thermal core, the container promotes uniform heat transfer for consistent and reproducible freezing performance. Its non absorbent foam design helps maintain freezer integrity without introducing liquids that could affect surrounding samples. The low thermal mass allows the container to return quickly to room temperature after removal, improving workflow efficiency between runs. Designed for 12 standard 5 mL cryogenic vials, the uniform radial layout promotes consistent freezing rates across all vial positions, while numbered vial locations simplify

Associates of Cape Cod Inc Pyrotell 0.06 EU/mL, 5 vials
Pyrotell lysate was the first LAL gel-clot reagent licensed by the US FDA. It is easy to use and is available in both economical multi-test vials and convenient Single Test Vials (STV's). Pyrotell lysate is a robust reagent, producing firm, easily read clots and is resistant to interfering substances. The gel-clot test does not require sophisticated capital equipment and software and is the simplest LAL test to implement. For standard use, a 1:1 mixture of Pyrotell lysate to sample is used. The reconstituted lysate is stable for 24 hours at 2–8°C or for up to 3 months at or below -20°C. May be frozen onceand will retain activity for as long as 3 months if stored at or below -20°C.
Alkali Scientific HotGuard™ Autoclave Safety Gloves, resistant to 260°C (500°F), 14 x 7in (36 x 18cm), red
HotGuard™ Autoclave Safety Gloves provide reliable protection when handling hot laboratory equipment such as autoclaved glassware, metal instruments, and sterilization trays. Manufactured from extra thick cowhide leather, these durable gloves offer excellent resistance to high temperatures while maintaining flexibility and comfort. A soft heat resistant cotton lining enhances user comfort during extended use and provides an additional protective layer against heat transfer. Designed in a universal one fits all format, the gloves measure approximately 14 inches in length to protect not only the hands but also the wrists and forearms. The three layer construction delivers enhanced insulation and safety, making them ideal for autoclave operations and other high temperature laboratory tasks requiring dependable hand protection up to 260°C (500°F).
Alkali Scientific Silanized Glass Vials with PTFE/Silicone Lined Solid Closure, Pre assembled, Flat Bottom, White Writing Area with Graduations, Sterile, 100/Pk, 8mL (17mm), 15 425 Screw Thread, Clear
Save time and reduce waste costs during quantitative analysis or material storage with Alkali Scientific™ Silanized Glass Vials. These vials undergo a vapor phase deposition silanization process, ensuring surface deactivation to preserve the integrity of sensitive materials or extracts. By eliminating active sites on borosilicate glass surfaces, silanization and siliconization enhance sample stability and recovery. Silanized for efficiency – Minimizes waste costs and saves time during analysis and storage. Enhanced surface modification – The silylating agent reacts with active groups on the glass surface, reducing reactivity and preventing materials from adhering. Maximizes analyte recovery – Ideal for trace analysis by inhibiting sample loss due to surface interaction.
