Electron Microscopy Sciences High Resolution Magnification Calibration Specimen 150-2DUTC with Pin
Model 150-2D is a very high resolution reference and traceable standards for magnification calibration of AFM, SEM, Auger, and FIB. It has a precision, holographic pattern that provides accurate calibration in the horizontal plane for very high resolution, nanometer-scale measurements.
The period is 144 nm pitch, two-dimensional array that is accurate to +/- 1 nm (calibration certificate will have actual pitch.) Surface: Aluminum bumps on Silicon, 4x3 mm die. Bump height (about 90 nm) and width (about 75 nm) are not calibrated.
For SEM an independent analytical lab has tested this specimen in a FE-SEM and found that the pattern was very uniform and the specimen was easy to image. No significant charging was observed in the voltage range 1-20 kV. This traceable, Certified Standard is a select grade.
Chemglass Life Sciences Column, Chromatography, 24/40 Outer Rodaviss Joint, 3/4in ID X 8in E.L., 2mm Stpk
Column, Chromatography, 24/40 Outer Rodaviss Joint, 3/4in ID X 8in E.L., 2mm Stopcock. Similar to CG-1192 but with a sealed in COARSE porosity fritted disc to support column packing. Column is constructed using MEDIUM WALL TUBING. Can be used as a gravity eluted column or a flash column (as described by W.C. Still, M. Kahn and A. Mitra of Columbia University in JOURNAL OF ORGANIC CHEMISTRY 43, 2923 [1978], and covered in U.S. Patent Number 4,293,422 dated October 6, 1981) when used with optional CG-1195 flow controller and CG-1194 reservoir. Column is supplied complete with a CG-182 open top cap and o-ring.
Chemglass Life Sciences Column, Chromatography, 24/40 Outer Rodaviss Joint, 1 1/2in ID X 12in E.L., 2mm Stpk
Column, Chromatography, 24/40 Outer Rodaviss Joint, 1 1/2in ID X 12in E.L., 2mm Stopcock. General purpose column having a PTFE stopcock and a top Rodaviss outer joint. Can be used as a gravity eluted column or a flash column (as described by W.C. Still, M. Kahn and A. Mitra of Columbia University in JOURNAL OF ORGANIC CHEMISTRY 43, 2923 [1978], and covered in U.S. Patent Number 4,293,422 dated October 6, 1981) when used with optional CG-1195 flow controller and CG-1194 reservoir. Column is constructed using MEDIUM WALL TUBING. Glass wool (not supplied) is used to support column packing. Lower end of the column has a round bottom. Connections between the column, reservoir and flow control adapter are made using Rodaviss joints. The unique design of the Rodaviss joint affords a grease free seal while holding glassware together without clamps. Column is supplied complete with a CG-182 open top cap and o-ring.
