CIGARETTE SMOKE EXPOSURE SYSTEMS Two types of systems are available as stock offerings. Custom systems are offered as well. Reduced Cost Manual System At $8750 (base price, FOB Westwood, NJ), CH Technologies announces the availability of an affordable cigarette smoke exposure system for medical and toxicology research. Patterned after published designs for smoke inhalation exposure, this system of directed flow inhalation exposure (mice are standard, other species are options) offers flexibility that is cost and space effective. Two cigarettes being smoked is standard. Manual loading and lighting are standard. Automation, multiple pumps and larger numbers of cigarettes are extra cost options. The patented Jaeger-NYU (directed flow) inhalation exposure technology is used. Exposure tubes provided are open tubes (standard). Closed animal exposure restraint tubes are also available (option). Respiratory measurements using plethysmography or the Pennock-Bergers-Jaeger system can be made during smoking (option). Almost any published protocol can be reproduced. Mainstream (standard) smoke exposures or mixed exposures (collection and mixing of main stream plus continuous side stream smoke, option) can be performed. Six animals is the standard configuration for the base unit. This manually loaded (and lighted) cigarette smoking system is driven by an automatically regulated piston pump. The type of pump used is standard in US smoke exposure studies. It offers a two second puff of 35 ml volume. The volume can be adjusted. A bell shaped profile as specified in ISO 3308 is used. Cigarettes are smoked with or without covering the aeration holes (manually set by the operator, based on insertion depth). Side stream smoke is collected for exposure use or for analysis (option). Loaded with one or two cigarettes at a time, the piston pump can cycle once per minute (a single two second puff per FTC and ISO regulations), twice per minute, 2.3 times per minute (as required in Canadian and some US state protocols),3,4,5 or 6 times per minute. Ignition as well as butt removal are manual (standard). Wood or paper matches, commercial butane lighter or similar ignition device, "Zippo-type" lighter can be used. Semi-automatic or full automatic ignition with an electrical or gas igniter are available (option). When a manually chosen point on the burning cigarette rod is reached (butt length), the pump is shut down and reloaded as desired. Animals may be kept in their restraint tubes until another exposure is started. The exposure unit, smoke generator and smoke pump are available in a variety configurations. Quotations will be given based on your specific needs and space considerations. In addition to an Intel based computer Pentium class computer with a free ISA slot, the smoking system requires 110/200 (60-50 cycle) electricity, a compressed source suitable for breathing and an approved smoke exposure space (i.e. a hood or similar ventilated cabinet). All units are sold with a one year limited warranty. Larger Inhalation Exposure SystemsLarger systems (12, 24,36, 48, 60 or 72) can be assembled for specific needs. The standard Baumgartner-Jaeger CSM 2070 is used in these applications. Pumps of the continuous or human puff profile type can be provided. Please call Dr. Jaeger for a quotation. |
