RESULTS:No significant differences were found in the determination results of the majority indexes in the determination of5%GS injection and0.9%NaCl injection in PVC and non-PVC containers vs.the glass bottle(P>0.05),however,the contents of the2solutions in PVC containers decreased(P<0.05);
In the PVC infusion package,the contents of insulin,isosorbide dinitrate and nitroglycerin vary from34.44%to80.80%,and the contents decrease percentage of which has a statistical difference vs.that of the glass bottle(P<0.05);
METHODS Acyclovir was dissolved with 5% dextrose injection and 0.9% sodium chloride injection respectively in PVC bags,three-layer plastic bags and glass containers. The storage conditions for the solutions were 4℃,25℃ and 37℃. Samples were removed at 0,0.5,1,3,6,8,12,24 hours,and their appearance,pH,related substances and concentrations were determined.
Phosphine in amounts as small as 30 ng per 1 can be stored for several days in glass bottles covered with rubber septa, filled with nitrogen, in the presence or absence of water or of an anaerobic bacterial culture.
We have established an assay system for determining cellular transformation in terms of anchorage-independent growth, using screw-capped glass bottles and a spontaneously transformed cell line that was derived from golden hamster embryo cells.
In glass bottles, the solution should be acidified to pH 1.
This study presents experiments with butyltin compounds showing that the storage of filtered natural seawater in the dark at pH 2 in pyrex glass bottles is suitable to preserve the stability of tributyltin (TBT) over 4 months both at 20-25°C and 4°C.
The cow milk analyzed from glass bottles showed a mean of 29 pg TEQ/l (range >amp;lt; 10 - 67 pg TEQ/l).
Photo-electric apparatus for detecting deviations of bottle height, diameter and vertically has been described. The apparatus checking bottles in-line can reject the defective bottles automatically.In order to overcome the interference of light transmittance of some bottle glasses, a control console with ou-off counter has been developed.
