13.600 - Piston Corer:
Description:
Position numbers refer to the schematic below.
An AISI 316 stainless steel heavy-duty releaser (pos. 1), based on
the Kullenberg principle, is mounted at the top. Up to 10 lead
weights (pos. 4) of 28 kg each can be mounted. The upper part of
the corer is made of AISI 316 stainless steel.
The corer tube (pos. 9) is either made of AISI 316 stainless steel
(Ø104/99 mm) or transparent PVC plastic (Ø110/99 mm). At the end of
the releaser hook (pos. 1) the 30 kg release weight (pos. 7) is
mounted.
At the bottom of the corer tube a piston (pos. 8) with a leather
seal is positioned. The piston is connected to the releaser (pos.
1) by a Ø8 mm AISI 316 stainless steel wire. During operation, the
corer tube (pos. 9) is released 1,7 m above the sediment as the
releaser weight reaches the sediment surface. The wire (pos. 8),
which has a slack of about 1 m, allows the corer tube to fall free
until the piston (pos. 7) is activated just before the corer tube
enters the sediment. The penetration depth can be regulated by the
total weight load (pos. 4). When the sample is to be retrieved, the
tube is positioned at two trestles and a piston rod (pos. 12),
operated by an AISI 316 stainless steel ratchet, presses out the
sediment sample for slicing.
Piston corer - other dimensions:
For other alternatives, we suggest looking at our
Gravity
Corers. They all support an extension kit, adding
piston corer functionality thus having a versatile 2 in 1 product
where you can switch forth and back within few minutes.
Furthermore, you will be able to use longer sample tubes.
