## Questions & Answers

**Q: What is the cost of optional output port to computer?**
A: There is no RS232 port as far as I could tell.  Even opened up the case and I didn’t see a place on the board where it should be located.

**Q: Is it fully functional?**
A: It will do the job. Big downside is that it must be done manually. It takes at least an hour to scan the band, 1 nm at a time.

**Q: Can this be used to find the absorbance of DNA?**
A: No, DNA does not absorbe in the visible region... but if you have a dye to stain the DNA it will be possible to determine the absorbance

**Q: Can I use a small volume cuvette with this instrument?**
A: If you are talking about the disposable plastic cuvettes, that is what comes with the spectrophotometer and you can use them as a size comparison.

Surprisingly good spectrophotometer. I was worried this thing would be a lemon but its actually pretty decent. You will have to do alot of math to get data out of it but it's definitly better than nothing ; )
