Our lab is in need of a new UV-Vis spec and I was wondering if there's a model/brand that folks might recommend (or advise against, for that matter). We need decent quality for not too much money, mostly just basic absorbance readings and obtaining spectra. Very infrequent kinetics work. If we need to plug into an old laptop/PC for some functions, that can probably be arranged too. Our current instrument (an LKB Ultrospec II from the '80s) has a carousel in it, but I don't think anyone ever uses that feature. Similarly, a split beam might be handy, but would rarely find use. Any suggestions would be welcome. -- ______________________________________________________________________________ Lou Hom >K'93 lhom@ocf.berkeley.edu http://www.ocf.berkeley.edu/~lhom/

A relatively low cost very compact spectrometer can be bought from Ocean Optics.

Universities also have access to an interesting "trade in" plan for their low end instruments http://www.oceanoptics.com/products/tradeineducation.asp. You can get a big discount by sending them your Ultrospec II. josh halpern > >"Louis Hom" <lhom@OCF.Berkeley.EDU> wrote in message >news:c9nm9p$2lji$1@agate.berkeley.edu... > > >>Our lab is in need of a new UV-Vis spec and I was wondering if there's a >>model/brand that folks might recommend (or advise against, for that >>matter).

It's used by students in lab and has stood up well.

You should at least look at the Nanodrop machine, which allows you to spec one microliter without the use of cuvette. (no affiliation)
