Liquid nitrogen storage freezer.

A tank of liquid nitrogen used to supply a cryogenic freezer for storing laboratory samples at a temperature of about 150 c controlled rate and slow freezing also known as slow programmable freezing spf 15 is a set of well established techniques developed during the early 1970s which enabled the first human embryo frozen birth zoe leyland during 1984. Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature. Modern vapor phase liquid nitrogen freezers are so well insulated that the sample space temperature is maintained at or below 190 c even if the lid is kept off. It need to be connected to liquid nitrogen storage tank or liquid nitrogen supply pipe through pipeline for using.

We offer liquid or dry storage depending on preference and each range is available in a range of sizes contact for more information. In an incident on january 12 2006 at texas a m university the pressure relief devices of a tank of liquid nitrogen were malfunctioning and later sealed as a result of the subsequent pressure buildup the tank. In applications where storage temperatures above 150 c are acceptable laboratory personnel have had to accept these tradeoffs between usability and reliability in selecting among conventional mechanical and cryogenic refrigeration. Ease of operation plus flexibility to operate vapor storage immersion storage or a combination of both to store any type or size of sample.

It is a colourless clear liquid with a density of 0 807 g ml at its boiling point 195 79 c 77 k. Wide lid opening for easy access to all racks. Stainless steel vacuum insulated vessel. Round space saving design.
