Multi corer with 4 or 6 tubes, ø110/105 mm.
72.000 - Multi corer	Application: The multi corer is used for sampling in chemical, geochemical, biological applications and oceanographic information. Quick change of tubes assures a high operational speed. General: Multi corer with 4 or 6 tubes, each ø110/105 mm, length 500 mm. A very solid design in AISI 304 stainless steel and a maximum weight of 950 kg ensure very high performance. Operating depth: Full oceanographic depth, >6000 m Advantages: Transparent sample tubes. Penetration depth can be adjusted within a large range, allowing use of shorter tubes. Tubes with less diameter can be used by an adapter. (Optional).
Manual: Manual in pdf format (1045 kb) can be downloaded here.	Maintenance: No need for special maintenance. All parts can be rinsed with salt water and a regularly use of silicone grease. For storing please rinse with fresh water.
	Principle of operation: While the multi corer is lowered into the sea, there is a full flow through the sample tubes in order to obtain an undisturbed sample. The top of each sample tube has a spring-loaded lid, which is in open position during the sampling. When the sample has been taken the lid will close and the resulting vacuum will hold the sample until the shovel covers the end of the tube.
	Closing the tube: Upon raising the multi corer and as soon as the tubes are leaving the sediment, a spring-loaded shovel is pressed in position under the sample tubes. It turns down, having a space of approx. 1 cm to the end of the tube. Finally the shovel is lifted against the tube to avoid exit of the sample.
	Quick change system: The sample tube has a sleeve at top which fit into the bracket and the quick change system allows a very fast change of tubes.
	Closing mechanism: A very solid design for the closing mechanism and adjustments for closing the tube.
	Weight station: 4 identical weight stations have room for a maximum weight of 640 kg. (32 weights, each 20 kg). Standard delivery includes 160 kg.
	Lead weight: Weight 20 kg. The multi corer will handle a maximum of 32 weights. (640 kg).
	Security lock: For your safety the security lock must always be attached while working with the corer as it will prevent an unintended release.
