The Waters fraction collector I was made by Advantec of Japan and was also sold as the Advantec 2120 super fraction collector. The racks have flexible test tube support holders so that more then one size of tube will fit into a given rack and there are more then one size of rack. This arrangement is less compact then that used by Gilson and ISCO but unless you are under pressure to save every last bit of bench space this will likely not be a problem.

Unlike the ISCO JR, we have not had any problems with the durability of the dispensing arm but we would rate it as being somewhere between the fragility of the ISCO JR and the sturdiness of the Gilson 203.

We have however encountered frequent discolouration in the plastic covers and the user interface is extremely annoying and counter-intuitive.

Here at 2H2, we support the metric system and feel the world would be much more productive if the imperial system was completely retired. With lumber, a "2 by 4" is not 2 inches by 4 and a 1/2 inch plumbing fitting has no dimension that is half and inch. These sorts of things can cause inefficiency but things get really painful when the two systems are mixed. Sadly this will likely be the case with the Waters fraction collectors. The valve requires metric fittings that also require flanged tubing. While we use metric fittings on the fraction collector half we normally send these collectors out with 1/16 Teflon tubing and 10/32 PEEK fittings on the detector side. If you would like metric fittings on both sides, please let us know in advance and we will accommodate this.

At one point all of our prices were posted online. Since the subprime fiasco of 2007 we have had an increasingly difficult time keeping our online prices up to date with the number of currencies that we normally quote in. Worse yet (for us) the prices of many instruments are in a state of flux. At this time(June 2010) we are in a buyer's market, this is an excellent time to buy used instrumentation, with prices approximately 10-15% lower then in 2007. Unfortunately we have had to switch from an online pricing setup to a quote-on-request one.

If you would like a quote on one of our fraction collectors please let us know:
-If you require the event cables for contact closure control and peak measurement
-What the maximum flow range you anticipate is(so we can send the correct bore of tubing)
-If you would like our standard two year warranty or our optional 90 day warranty.

If you have any questions at all please don't hesitate to contact us. Our sales people will never "follow up" with you afterwards and if you contact us by email we will never add you to our spam list. We do not and will not, ever have one.
