History
Concepts
1.1 Sample preparation instrument
- Categories used in the SeaDataNet project to classify devices that alter the nature of a sample prior or during property determination.
- Alternate labels: SeaDataNet sample processor categories, sample processors,
- Concept URI: http://vocab.nerc.ac.uk/collection/L21/current/ICAT02
1.1.1 benthic incubation chambers
- Child of:
ICAT02 - A device that isolates a portion of seabed plus overlying water from its surroundings. Either returns the entire system to the surface or incorporates sampling devices and/or in-situ sensors.
- Concept URI: http://vocab.nerc.ac.uk/collection/L05/current/151
1.1.2 shipboard incubators
- Child of:
ICAT02 - A device mounted on a ship that holds water samples under conditions of controlled temperature or controlled temperature and illumination.
- Concept URI: http://vocab.nerc.ac.uk/collection/L05/current/81
1.1.3 in-situ incubators
- Child of:
ICAT02 - A rig that allows water samples to be retained from where they were collected whilst physically separated from their surroundings. Includes small-scale incubation rigs and mesocosms.
- Concept URI: http://vocab.nerc.ac.uk/collection/L05/current/82
1.1.4 centrifuges
- Child of:
ICAT02 - Devices that separate the liquid and solid phases of a sample through forces exerted by rapid rotation.
- Concept URI: http://vocab.nerc.ac.uk/collection/L05/current/83
1.1.5 sieves and filters
- Child of:
ICAT02 - Devices that separate solid particles larger than a particular size from a sample collected by another device that is a suspension of solid particles in a liquid or gas.
- Concept URI: http://vocab.nerc.ac.uk/collection/L05/current/84
1.1.5.1 Stand-alone pump
- Child of:
84 - A submersible battery powered water pump that sucks water through various filters leaving the materials of interest on the filter for analysis. SAPs are deployed clamped to a hydrographic wire and may be used to sample at depths of up to 6000 m. A SAP can pump thousands of litres of water over a few hours.
- Alternate labels: SAP
- Concept URI: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0500
1.1.6 biorectors and chemostats
- Child of:
ICAT02 - Devices in which controlled conditions are maintained for a chemical process to be carried out by organisms or biochemically active substances derived from such organisms.
- Concept URI: http://vocab.nerc.ac.uk/collection/L05/current/85
1.1.7 equilibrators
- Child of:
ICAT02 - Devices in which samples and carriers are brought into chemical equilibrium prior to analysis. For example, a shower head or tower full of marbles used to equilibrate water samples with air that is subsequently analysed for carbon dioxide to give pCO2 in the water sample.
- Concept URI: http://vocab.nerc.ac.uk/collection/L05/current/EQUIL
1.1.8 thermal cyclers
- Child of:
ICAT02 - Instruments that repeatedly heat and cool samples in a series of steps. They are typically used to amplify segments of DNA via the polymerase chain reaction (PCR). They can also be used to facilitate other temperature-sensitive reactions, including restriction enzyme digestion or rapid diagnostics.
- Concept URI: http://vocab.nerc.ac.uk/collection/L05/current/LAB50
1.1.9 homogenisers
- Child of:
ICAT02 - A piece of laboratory or industrial equipment used to disrupt and make uniform samples of various types of material, such as tissue, plant, food, or soil.
- Concept URI: http://vocab.nerc.ac.uk/collection/L05/current/LAB52
