Cryogenic Storage Vials
Small, capped vials designed to withstand ultra-low temperatures; various capacities; may be sterile, non-sterile, and/or autoclavable; includes internally and externally threaded vials; ideal for sample storage in vapor state liquid nitrogen.
Cryogenic storage in the laboratory is used to preserve samples with liquid nitrogen, a method that requires special products that can tolerate low temperatures without compromising the samples. The U.S. National Institute of Standards and Technology defines cryogenics as related to temperatures below −180°C (−292°F).
Cryogenic storage vials, cryogenic storage tubes, and cell culture cryogenic tubes are designed to safely store samples, and may also be used at general cold-storage temperatures.
Cryogenic vials and tubes have some common characteristics. They are made from non-cytotoxic and non-mutagenic plastic resins and are pyrogen-free. They are sold individually or in bulk packaging and in uncapped or non-sterile varieties for less demanding uses. Sterile tubes meet a SAL of 10-6.
Most cryogenic tubes or vials have screw-style closures that ensure the caps stay on in spite of temperature and air pressure changes. Cryo tubes or vials are available with either internal or external threads. Because the caps fit over the outsides of the tubes, external threads help maintain the sterility of samples.
Some cryogenic storage tubes have round bottoms and others are skirted so they can stand alone. Vials may be sized for specific applications, such as those that need to fit inside long tubes or canes during storage.
In addition, many cryogenic storage tubes come with a writing area on the side of the tube for labeling. Color-coding markers and caps also exist to help organize samples by type, researcher, etc.
Special cryogenic storage canisters are used to contain the liquid nitrogen needed for cryogenic storage.

Alkali Scientific CellPro™ 1.8mL Cryogenic Vial, Self-Standing, External Thread, Sterile 50/pk, 500/cs
CellPro™ Cryovials are designed for safe storage of samples at temperatures as low as -196 °C (gas phase of liquid nitrogen only). Cryogenic Vials with externally threaded caps have a special screw cap designed with silicone O-rings to avoid the risk of sample contamination. The silicone O-rings allow for expansion and contraction in liquid nitrogen environments associated with long term, -190°C storage. CellPro™ Cryogenic Vials are manufactured from high visibility polypropylene for stability in extreme temperature conditions. CellPro™ Externally Threaded Cryogenic Vials provide a safe and secure tube for ultra-low temperature storage of valuable cell cultures, clinical hospital samples and biological samples. All CellPro Croyvials are sterilized by E-Beam and are non-pyrogenic, DNase/RNase and human DNA free.
Alkali Scientific 4 x 1.0mL GENEFECT™ Transfection Reagent
GENEFECT™ is a new generation cationic polymer gene transfection reagent. It has several unique features necessary for efficient transfection, such as DNA condensation and endosomal release, which can improve gene transfection efficiency. Compared with cationic lipids, cationic polymers are very stable, easy to handle and more resistant to serum in cell culture. These advantages make gene transfection much easier and reproducible. GeneFect are widely used for both primary cell and established cell lines. Ideal for transient and stable transfection. GENEFECT™ Transfection Reagent prodcues a gentle transfection method for problematic cell types including primary cells. GENEFECT™ produces higher transfection efficiencies across a wide range of cell types and increased gene expression with very low toxicity.
