|The sampling orifice is situated in the upper-lid
casting, allowing the particle matter to be drawn
vertically into the orifice depositing the sample onto a
moving adhesive strip or glass slide. This design offers
an isokinetically stable condition and the trap has an
efficiency of approximately 97%. The performance is
closely similar to the standard BURKARD Seven Day
Volumetric Recording Spore Trap as described by Hirst in
1952 (Ann. Appl. Biol. 39, pp 257-265).
Interchangeable heads can be supplied for impaction of the sample directly onto glass slides for 24-hour work. Each instrument is supplied complete with an outflow turbine pump for specified voltages 12 v d.c. to 110 v 60 Hz; 220 v 50 Hz. The instrument can be connected to an external vacuum source making it completely safe in hazardous areas.
Construction and Equipment Details
Robustly constructed to withstand long-term operation in hospital and industrial environments, the instrument is finished in hammer beige enamel with stainless steel and corrosion resistant fittings. Working units are easily detachable for adjustment on site or in the laboratory.
