The Wildco® standard KB core sampler is a
messenger-operated gravity type core sampler
allowing unrestricted flow of water through its core
tube during descent.
The force of the water through these samplers
during descent is not required to hold the top valve
open. The result is less frontal wave. This is
particularly important where there is a soft
water/bottom interface or where a more accurate
representation of organisms in the water/bottom
interface is required.
Compared to the Ballchek sampler, KB core
samplers include a messenger-operated valve closure,
allowing the sampler to remain open until the
operator feels that the sampler has a solid sample.
When the seal is closed by the messenger, a partial
vacuum is created inside the core tube as the
sampler is raised, thus allowing collection of all
but the soupiest samples.

The overall weight of the standard KB core
sampler head, without core tube, is approximately 18
pounds. Core tube length is 20".
Tube Weight. A fourteen pound weight is available
which may be attached to either the standard or
heavy KB samplers at the top of the core tube if
additional weight is desired on either sampler.
Note: these can be used on all of the Wildco® 2"
core tubes.
Top Weight. A twelve pound weight is also
available which may be attached to the top of the
sampler around the trip head. This weight may only
be used with KB samplers.
Heavy-KB core sampler. May be chosen where
greater weight is desired. Weight of the heavy KB
head, without core tube, is 41 pounds.

Converting the standard KB. If you have a
standard KB sampler that you wish to convert to the
heavy KB, the base of the standard KB may be removed
and replaced with the heavy base, thus increasing
the overall weight of the sampler. Weight of the
heavy KB base is approximately 31 pounds.
All KB core samplers come complete with a
split-barrel tapered nose messenger which is
required for operation, as well as 100 feet of
aircraft cable and cable fittings. Winches must be
ordered separately.
A stabilizing fin is not included with the KB
samplers, and may be purchased separately to be
attached to the top section around the trip
mechanism for added stability. Note: it is possible
to add either a stabilizing fin or a twelve pound
top weight, but not both, to the KB at the same
time.
Complete core sampler kit includes one 316
stainless steel core tube (liner type) measuring
20"L x 2" ID, two plastic liner tubes with caps,
three eggshell core catchers, two lexan nose pieces,
one messenger, and 100 feet of aircraft cable.
Optional wooden case available.
