- Polycarbonate tube: for core collection: ~7 cm (2.75 inch) outer diameter, 1.6 mm (1/16 inch) wall thickness, lengths up to 3 m (10 feet).
- ABS/black plastic pipe: secondary liner for cores extruded from Livingstone corers. 5-, 7.6-, or 10.1 cm (2-, 3-, or 4 inch) inner diameter, schedule 40 pipe (~5 mm / 0.2 inch wall thickness), split in half lengthwise, paired.
- Endcaps: slip caps for polycarbonate tube, ABS pipe, and several other tube diameters.
- Zorbitrol: sodium polyacrylate absorbent powder to stabilize water above unconsolidated surface sediment cores.
Based on the publication by Tomkins et al. (2008), LacCore has recently begun using Zorbitrol (sodium polyacrylate) polymer gel to fix the watery surface interfaces of lake sediment cores. We've found that Zorbitrol is an excellent replacement for the material we used previously, floral foam, and a nice alternative to extruding the top of the core in the field (though field extrusion is still required for certain types of cores and analyses).
Zorbitrol is a powder used in the health care industry as a bodily fluid spill absorber. Please read the MSDS (available online) and particularly the Tomkins et al. paper cited above for caveats about its use. The powder is available from a number of suppliers that can be found online, and LacCore also has a supply from which we can send you a small amount to test (you typically have to buy a case of six bottles from online healthcare suppliers, and you only use a few grams per core) for a nominal shipping and handling charge. Please contact Amy Myrbo () for more information.
Zorbitrol will make you swear off floral foam for good.
LacCore purchases Zorbitrol from Shilog Medical Supply.
- Specimen Cups: screw-top sampling containers for sub-sampling.
