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 2mL Amber Sample Vial, Borosilicate Glass w. Black Phenolic Cap & liner, supplied in trays, includes VIALS & CAPS, case/144
2mL Amber Sample Vial made from high quality borosilicate glass designed for reliable storage and handling of light sensitive laboratory samples. The amber glass construction helps protect contents from UV exposure while maintaining chemical stability for sensitive reagents, solvents, and analytical samples. Each vial is supplied with a black phenolic cap and compatible liner to provide a secure, leak resistant seal that helps prevent contamination and evaporation during storage or transport. The vials are packaged in convenient trays for organized handling and easy access in laboratory environments. Includes both vials and caps, ready for immediate use in analytical, pharmaceutical, research, and quality control laboratories where dependable sample containment and protection are required. Case of 144.

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
Alkali Scientific Silanized Glass Vials with Septum Screw Cap, PTFE/Silicone Lined, Flat Bottom, White Writing Area, Sterile, 100/Pk, 4mL (15mm), 13 425 Screw Thread, Amber
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.
Alkali Scientific CellPro™ 8 Channel Pipettor 1 10µL, autoclavable, calibration key included, Accuracy 8.0 to 2.0%, Precision <6.0 to <1.2%
CellPro™ 8 Channel Pipettor 1 10µL is designed for accurate and efficient liquid handling in molecular biology, microbiology, and laboratory workflows requiring simultaneous multi sample processing. This precision pipettor features a durable construction and an autoclavable design, allowing safe sterilization without compromising performance. The ergonomic body reduces hand fatigue during repetitive pipetting tasks, while the included calibration key allows convenient in house adjustments to maintain measurement accuracy. With a volume range of 1 10µL, it provides reliable performance for low volume applications such as PCR setup, reagent dispensing, and microplate work. Accuracy ranges from 8.0% to 2.0% and precision from <6.0% to <1.2%, ensuring consistent results in routine laboratory procedures.
