Labconco 7910010 RapidVap N2 Evaporation System with RS-232 Link, 115V, 50/60Hz-cover
Labconco 7910010 RapidVap N2 Evaporation System with RS-232 Link, 115V, 50/60Hz

Labconco RapidVap N2 Evaporation System with RS-232 LinkThe RapidVapN2 Evaporation Systems offer a m (more)ore efficient, automatic alternative toKuderna-Danish and rotary evaporators and may be used with a broad range ofaggressive chemicals. In RapidVap N2 Systems, a stream of nitrogen or dry gasis directed downward onto the surface of the sample. Nitrogen blow down reducesthe partial pressure directly over the liquid to speed evaporation and helpremove the solvent as it evaporates. Nitrogen may be programmed for 2, 4, 6 orall 8 tube locations. Vortex motion and dry heat may also be applied to furtheraccelerate processing. The block holds eight large samples, up to 450 milliliters each, making itefficient for environmental and residue testing. An accessory block that holdseight 170 milliliter tubes suitable for solid phase extraction is alsoavailable. In many of these applications, the samples should not go to dryness.The unique Cool-Zone block and tube design significantly reduces theevaporation rate after end point is achieved. The Cool-Zone insulates thesamples and allows the researcher adequate time before the samples reachdryness to remove them or to perform solvent exchange procedures. Alarms thatsignal when timed end point has occurred and when the RapidVap senses that theprocess is nearing completion allow for unattended operation.INCLUDED: The Labconco 7910010 RapidVap N2 Evaporation System with RS-232 Link, 115V, 50/60Hz includes: - Exhaust Hose - Clamp - Sample Tube Caps x 8 - Heat Transfer Grease - RS232 Cable Assembly - Power Cord - Operator's Guide - Manufacturer's Documentation - 1 Year Manufacturer's Warranty
