SAR-GEL ® Water Indicating Paste .............................................<br />
Water indicating paste provides a fast, reliable way to detect water bottoms in<br />
storage tanks containing gasoline and gasoline/alcohol blends, diesel, jet fuel,<br />
fuel oil, solvents and other materials.<br />
Advantages:<br />
• Easy to apply - no messy jars, no need to mix, easy cleanup<br />
• No guessing - complete color change from white to brilliant pink<br />
• Faster reaction - immediate detection means less time wasted<br />
• Easy to see water line - does not run<br />
• Useful in detecting water content in laboratory recycled reagents,<br />
as well as other stain line reagents and solvents such as xylene and absolute alcohol<br />
Sodium Polyanethole Sulfonate [52993-95-0] AH4g .............................<br />
[CH(C 6 H 3 [SO 3 Na]OCH 3 )CH(CH 3 )-] x<br />
For inhibition of blood coagulation in vitro and to stabilize collodial solutions like milk and gelatin.<br />
Sodium Thiosulfate Pentahydrate, ACS Grade [10102-17-7] H2g ..................<br />
MW 248.18<br />
Used to remove silver bromide crystals that remain in the photographic emulsion after latent image<br />
development. Techniques of Autoradiography, Rodgers, 25 (1973)<br />
Stains-all [7423-31-6] H5g ...................................................<br />
MW 559.6<br />
Stains proteins red, DNA blue, and RNA bluish-purple. Also useful for staining acid polysaccharides.<br />
Biochim. Biophys. Acta, 264, 73 (1972); Anal. Biochem., 29, 421 (1969); 56, 43 (1973); J. Histochem. Cytochem., 22, 1169 (1974)<br />
TDMAC-heparin (Tridodecylmethylammonium heparinate), 2% (w/w) solution CH5g<br />
TDMAC-heparin (Tridodecylmethylammonium heparinate), 7% (w/w) solution CH5g<br />
TDMAC-heparin has proven to be an effective antithrombogenic coating when<br />
applied to a variety of materials used to make catheters and tubing. For most<br />
materials a simple immersion of the device to be coated, air drying and sterilization<br />
are sufficient to provide an antithrombogenic surface that will resist clot<br />
formation. Technical Data Sheet #172<br />
