Specimen holders for simultaneous critical point drying of multiple biological specimens.
Specimen holders were developed for simultaneous critical point drying of multiple specimens of monolayer cell cultures grown on Leighton tube glass cover slips or for specimens of cells collected on silver or cellulose membrane filters. The use of these multiple specimen holders makes it possible to process several specimens in parallel and thus significantly reduce the time required for handl...
متن کاملUltrastructure of Ciliary Microtubules after Critical Point Drying
Many studies have been conducted on the fine structure of the "9 + 2" microtubules from cilia and flagella . The techniques used include both thin sectioning of whole cilia or flagella and negative staining of isolated microtubules . In this study, cilia from four diverse species of ciliate protozoa : Euplotes eurystomus, Spirostomum ambiguum, Tetrahymena pyriformes, and Colpoda ; and sperm fro...
متن کاملAn Alternive to Critical Point Drying for Preparing Meat Emulsions for Scanning Electron Microscopy
A rapid sample drying technique is described which is useful for the simultaneous preparation of large numbers of samples as an alternative to critical point drying. The cryofractured face of meat emulsions was visualized after appl ying this technique . The fine structure of 1 ipids and proteins were found to be well preser ved in comparison to other reports which used critical point dried mea...
متن کاملChamber for critical-point drying of nematodes and other biological specimens.
Processing nematodes for scanning electron microscopy requires transfer of specimens through a series of fixatives and dehydrat ion fluids (1, 2). Preferably, all steps of fixation, dehydration, and drying are performed in the same vessel to avoid repeated handling of specimens. De Grisse (2) described small chambers made of nylon mesh and glass tubing for this purpose, and Marchant (3) constru...
متن کاملCritical Specimen Sizes for Tensile-Shear Testing of Steel Sheets
Tensile-shear testing results are influenced not only by the quality of spot welds, but also by the dimensions of testing specimens. Experimental and numerical studies have been conducted on determining critical sizes for tensileshear testing of resistance spot welded specimens. Statistical methods have been employed, from planning stages to the analysis of results, for the purposes of getting ...
