WHEN constructing a rotary film evaporator 1 without a rotating vessel for solvent recovery, we required a spinning joint which would remain airtight at a reduced pressure of 15–20 mm. mercury.

This synthesis involved individually adding nucleotides to a chain, and back then, we did it manually, so it took more time. However, one group developed dimers of some of these bases that could save ...

Utilizing a rotary evaporator, the filtrate was concentrated to a relative density of 1.1-1.3 and set aside. A random sample of successful model mice was divided into five groups as follows: model (MC ...

Hopefully you can reuse the under-dash components (evaporator core and fan) and replace only the expansion valve ... compressor with a Sanden compressor or one of its many Chinese-made clones, I’ve ...

Remember rotary engines? The Felix Wankel-developed (stop tittering at the back) rotating engine design as flirted most famously with by the phenomenally fast JPS Norton racers, not to mention the ...

which was removed by filtration of both layers to facilitatetheir separation. The organic solution was dried over anhydrous sodium sulfateand concentrated with a rotary evaporator. The concentrate was ...

The compressor is a small compact rotary-style Behr unit commonly called ... flushed them and the evaporator and condenser with mineral spirits until they ran clear, found a good used compressor ...

We demonstrate highly efficient energy harvesting devices for dim-light application under 200 lux irradiation using dye-sensitized solar cells (DSCs) and perovskite solar cells (PSCs). The ...
