Introduction. PCR Plates are made of specially formulated high quality polypropylene. Nature-color PCR plates are compatible with most thermal cyclers and are ideal for ideal for high throughput screening thermo cycler applications. Smooth, thin, uniform well walls ensure accurate thermal transform.

Nylon syringe filters (25 mm, 0.2 μm membrane) were purchased from VWR or Macherey-Nagel. Microwave synthesis In a typical synthesis, 0.5 mmol of tungsten hexachloride was added to 10 mL of stirring benzyl alcohol in a glass microwave vial with an inner volume of 30 mL in an N 2 -filled glovebox (Vacuum Atmospheres).

2018/9/15 · As over 90% of the determined microplastics were smaller than 5 μm, our results show that it is of great importance to analyse food for the smallest size of microplastics. Regarding potential health effects for humans due to the oral intake of microplastics, in particular the smallest microplastics (<1.5 μm) are considered critically ( EFSA, 2016 ; Yoo et al., 2011 ).

2019/4/10 · One useful interaction of UV and plastics is with fluorescent whitening agents (FWA). In natural light many polymer products can appear to have a yellow appearance. But by adding a FWA the UV light absorbed is then emitted in the blue region of visible light (400-500nm wavelength), instead of the yellow region.
