Hello:
I am a chemical engineering university professor and thesis advisor with extensive experience writing, rewriting, reviewing, proofreading and editing academic essays, articles, technical reports, thesis, books related to science and technology, rebuttal letters and other documents in English and Spanish languages. Also, as a chemical engineer, I know very well the liquid diffusion process.
Based on this experience I can proofread your lab report for $30 in 30 days. Also, before to reach a final decision about this task, I would like to see first your lab report. Depending on the number of pages or words we can make a deal about time and costs.
Sincerely
Iraides
