Reproducibility problems have delayed the advancement of Science. The chemical resistance of synthetic sapphires and quartz (glassware) was measured to quantize the dissolution of solid laboratory instruments. Glassware laboratory instruments have been used for many years in chemical/biomedical experiments. The choice of laboratory instruments is important for successful experiments since they may be dissolved in chemical. The chemical resistance is compared between synthetic polycrystalline sapphires, synthetic monocrystalline sapphire, and quartz (glassware) where tested chemicals include HCL, HNO3, HF, HF/HNO3, H3PO4, H2SO4, and NaOH respectively. For high reproducibility, the result suggests that we should use the high chemical resistant laboratory instruments including synthetic polycrystalline/monocrystalline sapphires, instead of glassware.
