A Simple Apparatus for Freezing-Drying Histological Specimens
MANY of the conventional types of freezing-drying apparatus employ an oil or mercury diffusion-pump, backed by a rotary pump, to obtain the high vacua necessary to ensure that the water molecules which escape from the specimens have sufficient mean free path to enable them to reach the vapour trap. Clearly, the efficiency of the freezing-drying process might be greatly increased if the specimen...
متن کاملFreezing Point Depression of Plasma ‡
In an earlier paper2 we have reported results demonstrating that changing the concentrations of the carbon dioxide and oxygen with which the bloods of sheep and goats are equilibrated has a measurable effect on the total osmotic pressure of the true plasma. At constant oxygenation the osmotic pressure of the true plasma is increased 0.9 milliosmoles/Kg H20 for each millimole of C02/Kg H20 added...
متن کاملAn apparatus for determining the sec0 ndary electron emission properties of nonconductors
The apparatus described allows the measurement of the secondary emission coefficient and the secondary electron energy distribution from nonconducting surfaces.
متن کاملMonitoring the Freezing Point of Buffalo Milk
The aim of this study was to evaluate the basic freezing point of buffalo milk. Bulk milk samples were collected from buffalo and cattle farms in Caserta area from 2008 to 2014. The analysis involved a total of 1886 buffalo milk samples and 1711 bovine milk samples. These were also tested for fat, protein and lactose contents by means of infrared spectrometry. The freezing point was determined ...
متن کاملA new method of freezing-point determination for small quantities.
To a very large extent progress in the field of invertebrate physiology is a measure of progress in the technique of manipulating small structures and analysing small samples. Within this field the study of osmotic regulation is no exception. Krogh (1938) has summarized the known methods of measuring osmotic pressure, applicable to quantities of fluid of the order of O-I-I-O cu.mm. The freezing...
