The Anoxomat system is highly efficient and cost effective at cultivating pathogens and attaining growth performance that easily equals or exceeds that of chambers or gas bags.
We estimate that a lab employing gas bags can generate up to several hundred pounds of hazardous waste per year as it grows bacterial cultures," said Pappas.
Worse scenarios are that the craft burned up in the atmosphere,or the chutes or gas bags failed.
Twelve hours after the voyage began, he was discovered, having become overcome by leaking hydrogen from the gas bags.
Benefits of the Anoxomat Mark II system include: -- Rapid achievement of anaerobic conditions, reaching anaerobiosis as quickly as one to three minutes as opposed to one to four hours for gas bags, -- Repeatable environmental conditions, with gas mixtures remaining consistent within 0.
While traditional approaches have centered on the use of anaerobic chambers or gas bags, a new technology utilizing automatic evacuation/replacement methodology offers attractive advantages for laboratory managers.
Mars Express went into orbit around Mars early on Christmas Day - about the same time that the British-built Beagle was supposed to land north of the Martian equator, its impact softened by gas bags and parachutes.
Protected by three inflatable gas bags, the lander is expected to bounce down like a beach ball, coming to rest at precisely 2.
The free, whitepaper, "Effectively Isolating Anaerobic Bacteria," discusses anaerobic chambers and gas bags as the traditional applications used in the isolation and testing of anaerobic bacteria and related organisms as well as explores a third, newer technology -- the Anoxomat anaerobic system.
7 minutes its speed had to be reduced to 36mph before three large gas bags inflated to surround the tiny craft in a protective cocoon.
This new free, whitepaper, "Effectively Isolating Anaerobic Bacteria," discusses anaerobic chambers and gas bags as the traditional applications used in the isolation and testing of anaerobic bacteria and related organisms as well as explores a third, newer technology - the Anoxomat anaerobic system.
Even so,Beagle 2 will hit the ground at 36 mph and bounce 12 times before cutting free from the gas bags.
