It is useful to determine storage conditions and to set inspection before use for single-use component, because breakage or contamination with insoluble visible matter and component interconnections may sometimes be difficult to detect at the time of receipt or may occur later during unpacking or storage.
In the signed-satchel realm, new is not necessarily better; indeed, some people wash before use for the crinkly, Rag and Bone anti-polished look.
Michel Roux demands that the milk should be brought to the boil, then allowed to cool before use for reasons I'm not entirely clear about – this is suggested in breadmaking, apparently because it stops the whey proteins in the milk hampering the bread's rise, but here, with an unleavened pancake, it doesn't seem to make any sense (or difference).
Therefore, viscosity of nanofluids should be thoroughly investigated before use for practical heat transfer applications.
The inner and outermost layers of the silk cocoon should be removed before use for the GBR technique.
The catalytic activity of solid base catalysts were scarcely affected by exposure of the catalyst to air before use for the reaction.
These gels were prepared from acrylamide (AAm) with various N,N′-methylenebisacrylamide (Bis) contents by free-radical crosslinking copolymerization (FCC) in water and dried before use for swelling experiments.
The data summarised in Table 1 were entered into the PNS software, segmented into raw materials (fossil and renewable resources), intermediates (e.g. raw material before use for energy production), products (e.g. electricity) and operating units (conversion technologies and piping).
The slides were placed in lysis solution (2.5 M NaCl, 100 mM EDTA, 10 mM Tris and 1%v/v Triton® X-100 (added immediately before use)) for 1 hour at 4°C.
Next, coverslips were carefully removed, and slides were submerged in fresh lysis solution (2.5 M NaCl, 100 mM Na2EDTA, 10 mM Tris HCl, and 1% Triton X-100, pH 10 (was added immediately before use)) for 1 h at 4 °C.
Agrobacterium tumefaciens AGL-1, which was obtained from the Zhejiang Provincial Key Laboratory of Biometrology and Inspection and Quarantine, was grown in YEB medium with 100 µg/mL rifampicin at 28 °C before use for A. tumefaciens-mediated transformation (ATMT) (Lacorte et al. 1991).
