Selecting the Proper Laboratory Freezer
Lab directors often make the costly mistake of using household freezers to meet specialized cold storage needs. While the pricetag of home models might make them appealing, consider the potential cost of entrusting your precious laboratory specimens and reagents to a general-purpose freezer. A failure – or even minor temperaturee fluctuation – can ruin samples and reagents in just minutes.
Lab freezers have evolved to accommodate a range of specialized lab storage requirements, and a quick review of these variations, and the benefits they convey, can save time and money – two resources in short supply!
