Portable Refrigerator/Freezer for EMS Applications

The SPR-FT26 Portable Refrigerator-Freezer Unit

EMS and other first responder personnel working in areas suffering extended power outages can maintain medical supplies requiring refrigeration by using the compact, portable SPR-FT26 portable refrigerator/freezer unit from Tovatech.

Power is supplied from the EMS vehicle’s 12-volt DC lighter socket, a 24-volt battery source or from an AC adapter connected to 110-volt emergency generators. A wheeled travel trolley is provided to facilitate on-ground transport.Weighing less than 30 pounds the lock-equipped SPR-FT26 portable freezer/refrigerator has a capacity of 20 liters or 0.7 cubic feet and an overall size of 17”h x 21.25”w x 14.25”d.  It functions either as a refrigerator or a freezer thanks to an advanced refrigeration unit and computerized digital control system.   The unit will freeze below -18˚C in an ambient temperature of 30˚C or be set to operate as a portable refrigerator or cooler.  Personnel using the unit should confirm that the cooling or freezing temperatures are … Read the rest

Protect your Investment in Lab Refrigerators and Lab Freezers

Scientific lab refrigerators and lab freezers are substantial investments necessary to insure compliance with storage regulations for pharmaceuticals, vaccines, enzymes, blood, plasma, cultures and similar products.  If these units malfunction due to improper operation and maintenance, your organization is not only subject to being cited for non-compliance by the FDA and/or other regulatory authorities but also the financial loss of the contents in the lab refrigerator or lab freezer.

While lab refrigerator and lab freezer manufacturers such as Norlake Scientific provide detailed instructions on the proper setup and use of these units, operating procedures should be detailed in your company’s operations manual to govern their use and maintenance during their service life.  As one example, floor plan reconfigurations in your lab or manufacturing facility may change, resulting in the lab refrigerator or lab freezer being moved.   Wherever they are relocated, care must be taken to insure the move is … Read the rest

How to Choose an Enzyme Storage Lab Freezer

Enzymes are the catalysts of the biochemical reactions that comprise metabolism; they do their job without changing themselves in the process.    Enzymes are responsible for bringing about almost all of the chemical reactions in living organisms. Without enzymes, these reactions take place at a rate far too slow for the pace of metabolism.*

Enzymes being studied by researchers must be stored in a enzyme freezer at temperatures in the region of -10 to -25˚C (+14 to -13˚F).  When stored at higher temperatures enzymes gradually denature and lose catalytic activity.  Proper storage conditions are essential to ensure that the enzymatic activity on the label is indeed the activity inside the bottle.   I have many not so fond memories of failed experiments in graduate school because the rather costly purified enzyme suspensions failed to perform as expected, all due to inadequate storage.… Read the rest

Primer on Laboratory Refrigerator & Equipment Validation

A controlled environment is critical to maintaining the potency and safety of pharmaceutical products across a supply chain stretching between R&D laboratories, manufacturing facilities, transportation and storage at healthcare facilities.  Examples of controlled environments include laboratory refrigerators, laboratory freezers, blood bank refrigerators, chromatography refrigerators, laboratory incubators, stability chambers and temperature test chambers.

Equipment such as this as manufactured by Norlake Scientific and offered by Tovatech is designed and constructed to comply with standards developed and promulgated by the FDA, the AABB, the Red Cross and other agencies.  Once the equipment is purchased, however, the facility operator assumes the responsibility of assuring it is installed and maintained according to FDA and related guidelines.… Read the rest
