Product News: Pressure control helps smooth biological sample concentration

20 Feb 2007

Genevac has introduced a new pressure control innovation for their popular miVac™ Duo and Quattro sample concentrators that enable the gentle onset of concentration and helps to prevent sample splashing.

The new miVac pressure controller gives accurate pressure readout at all stages of sample concentration and provides full control of pressure and vacuum ramping capability. Unlike 'open-access' blowdown evaporator systems that often have no means of preventing sample splashing during concentration - miVac sample concentrators with pressure control minimise the dangers of sample cross-contamination and enhance solvent recovery.

The miVac sample concentrator range was designed to meet the requirements for careful and speedy drying in most biological applications. Special methods for drying aqueous and alcohol-based samples are included in all the miVac models. A range of concentrators feature capacity from six to twenty stacked shallow-well microplates or 48 to 200 micro centrifuge tubes of 1.5ml size. The miVac concentrators feature full LCD display with digital controls and programming of time and temperature. A range of suitable vacuum pumps is also available, including 2-head and 4-head diaphragm pumps and an ultra-low vacuum Scroll type pump.
