Gravity Corer Ø88,9 mm

gravety_corer_1.jpg

Application:
The 13.100 B Gravity Corer Ø88,9 mm is designed for taking samples in sandy sediment featuring a detachable core tube with a maximum length of 6 m, (optional). Up to 12 m in soft or muddy sediment.The corer is fully manufactured from AISI 316 stainless steel. Finish: Electro polish.

The top of the corer has 6 steering fins and below a platform with room for a total of 10 lead weights, each 20 kg. (Standard delivery comes with 2 pcs of lead weights).

13.540 Gravity corer, complete, consisting of:
• 1 pc corer body with steering fins and weight platform
• 1 pc corer tube AISI 316 stainless steel. Length 1500 mm
• 2 pcs lead weights, 20 kg each
• 1 pc orange peel closing system                                         
• 1 pc carver
• 1 pc PVC internal liner, grey, 1500 mm
• Weight: 130 kg (with two lead weights)
• Max. weight with 10 pcs lead weights: 290 kg
• Comes with 1 package of spikes 3,4 x 90 mm (13.185)

Extending the length of the 13.100 B Gravity Corer:
Each core tube have a length of 1,5 m, by using a coupling device (13.183) you are able to extend the overall tube length of the corer by 1,5 m in each interval.

We recommend the standard size for the core does not exceed 3 m, however in very soft sediment samples of 6 m or up to possible. As an alternative, KC Denmark offer a variety of larger Gravity Corers capable of taking longer samples (13.770 Gravity Corer Ø121 mm or 13.750 Gravity Corer Ø140 mm), we recommend 10 lead weights for a 3 m sample or longer on our 13.540 Ø101,6 mm Gravity Corer.

Corer tube dimensions:
O.D Ø88,9 mm/I.D Ø81 mm x 1500 mm.

Plastic liners (grey PVC).
Dimensions: O.D 75/I.D 71 mm x 1500 mm.

Plastic liners (partially transparent, light blue colour).
Dimensions: O.D 75/I.D 71 mm x 1500 mm.

13.160 - Extension for piston corer functionality.
