Product Details
Burkard Scientific produce a variety of useful sampling devices
for agricultural research. The Univac Sampler has been upgraded
in performance, and improvements in construction have increased
the static vacuum by 50%. Using a 4-stage high performance turbine
150 inches of water can be achieved at the sampling point.
Now a kilo lighter in weight and powered by the Kawasaki H43
2-stroke, the sampler enjoys the advantages of electronic ignition
with a maximum speed of 7000 rpm. A protected exhaust directs
unpleasant fumes to the rear and for additional operator safety
the 1.25 litre fuel tank is mounted beneath the engine unit.
A 2m clear plastic wire-reinforced sampling hose is retained
in position by vacuum created at low engine revolutions. The
suction cup is automatically released when the throttle is closed.
The collected material can be stored in the electrolytically
formed perforated container located within the plenum chamber,
or in a variety of paper bag inserts. Commercial paper towels,
sealed at the sides, provide inexpensive, easily obtainable disposable
collecting bags. They can be held in place by a rubber band around
the collecting tube within the suction cup. Various types of
collecting funnel can be attached to the sampling tube.
The standard Kawasaki engine (internationally available) can
be replaced without modification to the recoil start or the ignition
system. Reliable electronic ignition, protected silencer and
ease of servicing are features of this apparatus.
