Laboratory Freezers
Laboratory freezers are used to store a variety of samples between −10°C and −30°C, including pharmaceutical, biological, and other commonly used laboratory materials. Products may be upright, freestanding, or under-bench models providing a range of sizes and capacities. An automatic defrost option is available on some products.
Laboratory freezers are essential items of equipment in many laboratories, especially those that require the safe and secure short-term or long-term frozen storage of temperature-sensitive biological or chemical materials.
A general-purpose laboratory freezer typically stores samples down to −25°C. An ultra-low temperature (ULT) freezer is intended for deep cryogenic storage of samples typically down to −80°C. Most freezers are built from robust and durable materials such as stainless steel, aluminum, or powder-coated sheet steel.
Laboratory freezers have a selection of internal storage layouts or compartments, some of which may be reconfigurable by the user. For example, they may have combinations of adjustable and exchangeable doors, shelves, baskets, trays, or special racking systems designed for the storage of cryogenic boxes, microplates, or cryotubes.
Laboratory Freezers Come Equipped With a Range of Standard or Additional Features:
• Energy-efficient, microprocessor-controlled refrigeration systems
• Digital, user-friendly touchscreen displays
• Lockable, card-entry or self-closing doors for extra safety and sample security
• Spark-free versions for storage of flammable materials
• Audio or visual over-temperature alarms
• Remote temperature monitoring with USB data download capability
• Inner doors and high-efficiency foam insulation to minimize temperature losses
• Highly efficient pump systems for fast cool-down times
• Fan-assisted forced-air circulating systems to remove moisture and minimize icing.
• Automatic gas-powered defrost systems
• CO2 or LN2 safety back-up systems in the event of a power or mechanical failure
Sigma Aldrich Fine Chemicals Biosciences TygonR formula E-3603 labo
TYGON(R) E-3603 non-DEHP laboratory and vacuum tubing delivers the same superior performance youve come to expect from TYGON products - but now in a formulation that contains a widely accepted substitute for DEHP plasticizer.TYGON(R) E-3603 laboratory tubing is specially formulated for resistance to flex fatigue and abrasion handles virtually all inorganic chemicals found in the lab and is less permeable than rubber tubing. The glassy-smooth inner bore helps prevent build-up to facilitate cleaning.TYGON(R) E-3603 vacuum tubing shares all these performance features and has extra heavy walls that will withstand a full vacuum at room temperature.features/BenefitsAlternative to DEHP tubingNew formulation delivers the same excellent performanceContains no BPAOutstanding chemical resistanceLot-to-lot consistency for reproducible resultsIncreases productivity in peristaltic pumps - outlasts other clear tubing 2 to 1Smooth polished inner boreNon-oxidi

GA International Translucent Color Freezer Tape 0.94" x 180' / 24mm x 55m Yellow From -80°C to +121°C (-112°F to +250°F)
Translucent freezer-grade tape, provided in various colors for the identification and sealing of tubes, vials, bottles, boxes, and other containers. Ideal for long-term storage in ultra-low temperature freezers (-80°C/-112°F) and for transportation on dry ice. Ultra-thin, this thermoplastic tape/laminate is see-through for easy identification of the contents of sealed containers. With its eye-catching colors, it is also ideal for color-coding of containers inside laboratory refrigerators and freezers. It can be written on with permanent markers or used as a laminate. Resistant to chemicals and reagents, multiple freeze-thaw cycles, and other harsh laboratory environments. The versatile tape can also withstand autoclaving on stainless steel containers (121°C/250°F, 20 minutes). Supplied in continuous roll format on a 3” core to fit most tape dispensers.
