SKC 1L Vac-U-Chamber GPS Systems FROG-4000TM includes a micro-SD cardThe SKC Vac U Chamber is a rigid air sample box that allows sample bags to be filled directly by using negative pressure provided by most personal air sample pumps. Since the air sample does not pass directly through the pump, both pump and sample contamination are eliminated. The Vac U chamber's rigid walls will not collapse under vacuum conditions. All surfaces in contact with the sample are constructed of stainless steel or PTFE for inertness.
