Improve Accuracy and Precision with Bonded Polymer Technology

A calibrated pipettor may be 99% accurate and precise, but tips can compromise such accuracy and precision by binding sample. Low binding tips improve accuracy and precision by utilizing Bonded Polymer Technology to bond a proprietary polymer to the tip resin. This advanced process creates a hydrophobic surface that reduces the surface tension of the interior wall of the pipette tip, resulting ...

Wavelet Analysis Based Ultrasonic Nondestructive Testing of Polymer Bonded Explosive

Polymer Bonded Explosives (PBX) are well-known explosives for the weapons, especially for the parts of some important weapon. Generally, they first are modelled in cylinder. One of the most important issues in PBX cylinder properties is the detection of its flaw. Each PBX cylinder may have flaws that influence the security, machine-performance and other important physical or chemical performanc...

An Ehrlich chromogen in collagen cross-links.

A well-characterized three-chain peptide [(Col1)2 X T9] from human type III collagen was a rich source of Ehrlich chromogen. The corresponding two-chain peptide [(Col1)2] was not, implying that the Ehrlich chromogen is a trifunctional cross-link. (Col1)2 X T9 also contained pyridinoline, which is not an Ehrlich chromogen. The 7S domain of type IV collagen also contained an Ehrlich chromogen.

Plasma chromogen and the endogenous creatinine clearance.

One of the troubles of using the endogenous creatinine clearance to measure the filtration rate is that plasma and serum contain chromogens, other than creatinine, which give a colour with the Jaffe reaction. The creatinine can, however, be isolated by adsorption on Fuller's earth (Gaebler and Keltch, 1928) and subsequently eluted with the alkaline picrate used for colour production (Borsook, 1...
