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
Electron Microscopy Sciences mPrep/s™ mPrep/s Kit Capsules Pack
mPrep/s capsules allow users to fix, dehydrate and embed specimens in a single vessel. They can be used in two ways. The first method is to entrap specimens in the bottom of the capsule using the removable, adjustable screen with the hand-held Insertion Tool (85010-03). The second method is to flex the screen open using the mPrep/s Workstation* (85010-06). With the screen opened, the user places a specimen in the screen and orients it to the desired position within the capsule. Once the screen closes on the specimen, it is held in place throughout fixation, embedding, and sectioning. No additional embedding molds are required, and the capsule itself easily fits in the microtome chuck.
The capsule is highly recommended for transmission and scanning electron microscopy, but can also be used for any sample preparation.
Includes: Storage box, 8 capsules, 12 screens, 8 blank label

Biotium Ultrafiltration Vial, MWCO=10K
Ultrafiltration can be used to rapidly and easily remove small molecules such as Tris, glycerol, glycine etc. from antibody solutions, to concentrate antibodies before or after conjugation, or remove free dye or biotin from antibodies after conjugation. The ultrafiltration membrane retains molecules with molecular weight (MW) larger than the cut-off, allowing smaller molecules to pass through into the filtrate collection tube. We offer centrifugal ultrafiltration devices with two MW cut-off options: MWCO=10 kD (10K) and MWCO=3 kD (3K). For ultrafiltration of proteins, it is recommended to use a MWCO 3- to 6-times smaller than the protein to be retained. Ultrafiltration vials with MWCO=10K are recommended for ultrafiltration of antibodies and proteins larger than 30 kDa. Vials with MWCO=3K are recommended for ultrafiltration of proteins larger than 10 kDa.Ultrafiltration is not effective for fractionating proteins (based on size) unless there is at least a 10-fold difference in MW.
