A few things determine the endurance of a pre-owned unit: how well it has been preserved, and how properly it’s designed. Regarding the latter, make sure you select a model that gets solid reviews. Performance areas to keep yourself updated of as you investigate evaluations are: systematic power, physical stability, production, ease of maintenance, and ease of use.
A poorly maintained autosampler may breakdown prematurely and fail to provide accurate readings. The simplest way in order to avoid buying laxly maintained purge and lure gear would be to demand a preservation history for each and agilent autosampler you take into account getting, even types which have received slight use. If the record shows gaps in maintenance, the best selection is to locate a various autosampler.
Used autosamplers can be found from various places, but you need to only get from an expert retailer of applied laboratory equipment. Though inexperienced dealers may possibly present appealing prices, buying equipment that’ll or might not be precisely examined is not worth the purchase price difference. Professional vendors precisely determine the situation of used autosamplers, and, if required, refurbish them before reselling them.
Some sellers don’t mind offering bad gear, and their business history usually reveals it. If you discover that the references of a retailer appear disappointed with its products, or its record at the Greater Business Office (BBB) shows a history of unresolved customer complaints, discover an alternative retailer who illustrates a devotion to customer service.
The best way to examine an autosampler’s state of use would be to inspect it firsthand. As obvious as electronic photos can be, they rarely reveal as much as the bare attention can easily see, and they seldom reveal the equipment from every angle. If you fail to happen to be the precise location of the supplier to check the equipment, employ someone to accomplish the inspection for you.
