Dextran sulphate is a polyanionic derivative of dextran produced by esterification of Dextran with chlorosulphonic acid. Dextran sulphate sodium (DSS) is the sodium salt which is a white to off-white powder freely soluble in water and salt solutions to form a stable, clear solution. The sulphur content is approximately 17% which corresponds to an average of 1.9 sulphate groups per glucosyl residue of the dextran molecule.

This disposable TargetDispo sampler is to take a target point sample at a position in the sample material that has previously been precisely determined. Sampler is closed while it pierces into the powder or granulate, when it reaches the sample removal point it is opened and then closed again, in this way a precise target-point sample is obtained.

For sampling bulk goods, cross-sectional samples can be taken from different sample depths. Suitable for use with a range of sample substrates from fine powder to coarse grain. Multi sampler has three or five separate chambers for taking samples at multiple depths in one action. Uno sampler has one chamber for taking a sample at one specified depth. All layer sampler has no chambers, three or five inlets and this allows one sample to be taken at multiple depths. Jumbo sampler has no chambers and three, five or seven inlets; with a 50 mm tube diameter this is ideal for larger grain sizes and quantities.

In nanoparticle manipulation and dry powder chemical handling, enclosures keep hazardous powders and particulates contained. Room air is pulled into the enclosure from the front, flows to the baffle, and finally passes through a ULPA exhaust filter (99,999% efficient on particles 0,12 μm in size) before returning to the laboratory or cleanroom.

Guanidine Hydrochloride is a protein denaturant and thus having an important role in molecular weight determinations.
Guanidine Hydrochloride is a strong chaotropic agent useful for the denaturation and subsequent refolding of proteins. This strong denaturant can solubilize insoluble or denatured proteins such as inclusion bodies. This can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Guanidine HCl is used in the isolation of RNA to dissociate the nucleoprotein into its nucleic acid and protein moieties. It is an inhibitor of RNase. Highly concentrated (6 - 8 M) Guanidine HCl solutions are used to denature native globular proteins. It apparently disrupts hydrogen bonds which hold the protein in its unique structure. However, there also is evidence suggesting that guanidine hydrocholoride may disrupt hydrophobic interactions by promoting the solubility of hydrophobic residues in aqueous solutions.
