12.110 - Van Veen grab - 250 cm²:
Sampler for collecting bottom sediments for biological, hydrological and environmental studies.
The Van Veen grab is based on the Van Veen design. The Van Veen grab is made of AISI 316 stainless steel and the surface is electro polished. The grab itself is manufactured from 3 mm plate (250 cm²), 4 mm for 1000 cm² and 8 mm for a 2000 or 2500 cm².
There are 4 sizes of Van Veen:
12.110 - 250 cm², (0,025 m²) - 3,14 L.
12.210 - 1000 cm², (0,1 m²) - 15 L. *
12.211 - 1000 cm², (0,1 m²) - 15 L (ISO norm)
12.310 - 2000 cm², (0,2 m²) - 50 L.
12.410 - 2500 cm², (0,25 m²) - 82 L (ISO norm)
12.421 - 5000 cm², (0,5 m²) - 165 L.
12.422 - 5000 cm², (0,5 m²) - 165 L (ISO norm)
* 12.210 grabs delivered after August 1, 2014 can be upgraded to ISO norm by adding 4 lids, part no. 12.211 L.
Can be achieved by adding 4 extra lead weights, 4 x 1 kg, item 13.310-4 (optional).
The small models are delivered with 4 lids; the 12.310 model Van Veen grab 2000 cm² has 2 lids available. By opening the lid(s) it is possible to take out one or more undisturbed sample to have a look at the stratification of the sediment without releasing the whole sample. See A/B on schematic:
Norwegian ISO standard:
We also provide Van Veen grabs supporting the Norwegian ISO standard which requires lids with stainless steel mesh (500 µm) and rubber mats to reduce the shock wave.
On request, KC Denmark A/S can also manufacture the 12.210 and 12.400 model matching Norwegian ISO standard (16665 Water quality - Guidelines for quantitative sampling and sample processing for of marine soft-bottom macro fauna). These grabs come with lids having stainless steel mesh and rubber mats to reduce the shock wave).
Other types of bottom samplers are made on request - please contact us for further information.
KC Denmark A/S provides two standard area sieves with various mash size, see below links for more information.
