NITROGEN blowdown evaporation has been adopted by many labs for the removal of chromatography solvents such as acetonitrile, dichloromethane, hexane, and methanol.
The latest blowdown evaporator from Porvair Sciences, the Ultravap Levante, is equipped with an RS232 connection and a remote command set, enabling it to interface with most current robotic liquid handling systems.
This automation-ready microplate evaporator should appeal to budget-conscious laboratory managers, the company says.
It provides real-time graphics on a full-colour touchscreen display, monitoring actual gas temperature, gas flow rate, and stage height.
Porvair Sciences says Levante handles even complex evaporation protocols effortlessly and automatically, with multi-step ramped programming and full alphanumeric program naming.
The machine is designed around a standard ANSI/SLAS microplate nest to accept most tube formats and racks.
Tubes up to 80mm in height are accommodated to allow the use of 2 Dram vials, 1.5ml HPLC vials, bar-coded tubes in racks and other common formats.
Evaporator heads match 24-, 48-, 96- and 384-well configurations.
The Porvair 96-well spiral needle head, which creates a vortex in appropriate plates to speed up evaporation, can be used on the Ultravap Levante.
The device can be operated with nitrogen or clean dry air from an in-house supply or gas cylinder.
