Carrier for Core Tubes

The carrier is used for convenient and safe transport of core tubes from the multicorer on deck to the laboratory. Equipped with two rubberized carrying handles and anti-slip parking feet, it is made of high quality polypropylene thermoplastic. Due to the low shear point and the concentrically aligned carrying handles should allow the samples to be carried safely even in rough seas.   We will gladly integrate your customer-specific logo into the structure upon request.   Technical specifications   Material: Polypropylene Core tube dimensions (Ø d x l): Ø 100 mm x 610 mm (others on request) Total weight (empty): 8 kg   Subject to technical changes.

Gravity Corer

Gravity corers are used to remove sediment cores from the seabed. The penetration depth depends on the type of corer, its weight, and the nature of the sediment. Depending on the corer type various deployment requirements in terms of the ship, the winch, and the slider or A-frame must to be fulfilled. We can offer corers in different weight classes and materials for core diameters between 60 mm and 125 mm and variable tube lengths.   We supply extensive accessories and wearing parts for your equipment. We also hold handling equipment and sample processing tools (e.g. extruders, core slicers, tube cutters, core catchers). We will also be happy to supply you with a non-standard gravity corer to suit your application.   Version GC 60 GC 90 GC 125         Tube       Inner diameter (mm): 50 - 100 90 125 Length per section (m): 0.5 ... 1 2.5 2 ... 5 Material: PC 1.4571 St-52         Liner       Dimensions (mm): - Ø 90 x 1.8 Ø 125 x 2.5 Length (m): - 2.5 5 Material: - PVC PVC         Weights       Qty. of weights: 12 5 17 (more is possible) Weight per piece (kg): 3 40 60         Total weight with one tube (kg): 90 300 1,300         Spare parts shipping frame, liner adapter, cutter, liner sleeves, liner end caps         Subject to technical changes.
