A 96-well clear-bottom black color micro-titer plate (NUNC cat. nr. 165305).

Clear and Flat bottom.

round bottom would distort the optical path, should be flat. Depending on used wavelength range, you might need UV-transparent plates...

What are you measuring? What wavelength? What volume are you able to use?

Geoff Margison, We are measuring absorbance of normal analyte, for quantification of phenol, flavonoids. Wavelength is in visible range. Volume used is 200 microliter.

Friedrich has correctly answered your question.

If the total volume was smaller (

Dear Sagar

My own experience demonstrated that the kind of bottom could affect absorbance reading. So flat bottom is recommended for chemicals analyis and round botton for microbial process.
