Chromatography Refrigerators

Posted on Jan 5, 2016 in Featured, Refrigerators and Freezers

chromatography refrigerator for protein purifiers pictureNewly updated to accommodate the use of protein purifiers within the chamber, our chromatography refrigerators can compensate for the heat created by such devices running inside the refrigerator. You can put equipment generating up to 400 watts of heat inside the chamber and still keep the research materials at 5.5°C without overworking the refrigeration system.

Our chambers come equipped with two access ports and an interior duplex outlet to function as an extension cord for equipment, such as protein purifiers. Three levels of shelving, adjustable every ½”, are also included. Casters, installed after the refrigerator is moved into your lab, allow the cabinet to roll away from the wall for access to the power cord or compressor cavity.

Our standard chromatography refrigerators have 24” deep shelves, but for applications requiring slightly more space, we also offer an extra-deep size with 28” deep shelving. Please look over our Accessories page to see the full list of options available on our equipment.

Laboratory Refrigerators

Posted on Nov 19, 2012 in Refrigerators and Freezers

powers scientific laboratory refrigerator picturesClassic, simple cabinet design with white, gray or black powder-coat finish and premium fabrication combine with high quality refrigeration engineering to provide a reliable, long-lasting laboratory refrigerator. Chilled air is circulated throughout the chamber by energy efficient fans to maintain the temperature at 4°C, ±1°C, when measured in liquid at the sensor. Adjustable, fully supported shelves (not the cantilevered type) each hold up to 125 lbs (57 kg) of evenly distributed weight.

Powers Scientific laboratory refrigerators are available in 11 sizes ranging from a compact 10 cubic foot model all the way up to a spacious 106 cubic foot model. They are built to order and may be fully accessorized to suit the application and meet the budget. Check out our Accessories page to see the long list of options.

Safety Refrigerators

Posted on Oct 12, 2012 in Refrigerators and Freezers

Safety Refrigerator

Flammable liquids such as methanol, acetone, ether, and others should be stored in a safety refrigerator rather than a lab refrigerator. This reduces the potential risk of fire and explosion between the fluorescent lights and fan motor (in the lab refrigerator) and the volatile gases these fluids generate. Safety refrigerators have explosion-safe incandescent lights and air circulation fans driven by a rotor from an exterior motor. No electrical source on these models is within 48” of the floor, per OSHA requirements. These fridges are designed for the safe, cold storage of volatile fluids in an OSHA Division II location (non-volatile, non-explosive rooms). Three models are available and most options from the Accessories page may be added to Safety Refrigerators.

Pass-Thru Refrigerators

Posted on Oct 12, 2012 in Refrigerators and Freezers

Pass-Thru Pass-Through Refrigerators

Pass-thru pharmacy refrigerators have sets of doors on both the front and back faces of the chamber. Typically the doors are the hinged type (swinging) which tightly seal in the refrigerated air to help maintain critical temperature uniformity. However, gliding doors offer a space advantage in tight passageways and are often preferred on one side of the unit.

Pass-thru pharmacy refrigerators come with an easily readable digital touch-screen display, making temperature monitoring a snap. The temperature data is stored on a mini SD card, which can be downloaded to Excel, allowing you to review the chamber’s historical temperature performance graphically. Also, a high/low temperature alarm alerts personnel to temperature excursions (e.g. if the door is left open too long, or a power outage occurs), and the alarm relay can be easily connected to a lab or pharmacy monitoring system.

Frequently requested options, such as an extra-deep size for 10% more space, stainless steel interior or exterior, trim kit, chart recorder, Swaglok® access port for external alarm sensor or double-direction drawers can be found on our Accessories page.

Pharmacy Refrigerators

pharmacy refrigerator vaccine storage pictures

Pharmacy Refrigerators have all the features needed to store medicine at the correct temperature. They come with an easily readable digital touch-screen display, making temperature monitoring a snap. Temperature data is stored on a mini SD card, which can be downloaded to Excel, allowing you to review the chamber’s historical temperature performance graphically.

A high/low temperature alarm alerts personnel to temperature excursions (e.g. if the door is left open too long, or a power outage occurs), and the alarm relay can be connected to a lab or pharmacy monitoring system. These refrigerators have glass doors, and the larger (2- and 3-door) models come with your choice of hinged (SD) or gliding (GD) doors.

There are many options available including additional shelves, drawers, solid doors, door locks, and full stainless steel construction. Check out our Accessories page for a complete listing of available options.

Several these chambers (the 10, 24, and 27 cubic foot models) meet the USP validation requirements and can be used for vaccine storage. For users looking for a larger vaccine storage option, please take a look at our Constant Temperature Refrigerators, all of which meet the USP requirements.

2-8°C Constant Temperature Refrigerators (Vaccine Storage)

Posted on Oct 9, 2012 in Refrigerators and Freezers

powers scientific constant temp vaccine refrigerator pictureConstant temperature refrigerators are guaranteed to maintain the USP-quality storage conditions specified for 2-8 degree Celsius refrigerators. These models are factory set to 5°C, and the temperature of the air inside the chamber does not get colder than 2°C or warmer than 8°C. They stand alone among scientific refrigerators in this regard, because most others have air temperatures that vary from 0-10°C during the refrigeration cycle. Such temperature swings are not acceptable when storing small volumes of liquid (vaccines, insulin, and similar pharmaceuticals) because the thermal weight of the material is too small to dampen the effect of wide temperature variations.

Constant Temperature Refrigerators were developed to meet the need for 2-8°C storage. They can be mapped with temperature sensors throughout and will meet the USP validation requirements (with ambient room temperatures of 60-80°C). They are available in 7 sizes, designed to fit through standard door frames. Each has a microprocessor control with digital temperature display for temperature reliability.

Some standard features are listed on the chart below, but please request a specification sheet for the model you need. Options such as Swagelok® access port for thermocouple entry, solid doors, additional shelves, door locks or solid doors, temperature alarm, chart recorder, RS-232 port, and stainless steel construction are a few of the accessories we offer. See our Accessories page for a complete list of options.

If you are interested in using one of these chambers for vaccine storage, please also take a look at our Pharmacy Refrigerators. Several of the available Pharmacy Refrigerator models (the 10, 24, and 27 cubic foot models) also meet USP validation requirements for Vaccine Storage, and may be available at a lower price point than the comparable Constant Temperature Refrigerator model.
