Porvair Sciences, Wrexham, UK, has launched its new generation Ultravap Levante nitrogen blowdown sample evaporator.
The second-generation system offers the many benefits associated with Porvair’s flagship evaporator, the Ultravap Mistral, in an affordable, easy-to-use package. This state-of-the-art single microplate evaporator is designed to meet the current needs of most chromatography laboratories while providing the future option of fully automating sample dry-down in applications such as LC/MS analysis, dry recovery, or reconstitution.
The compact, standalone Ultravap Levante is fully programmable and easy to control from a robot liquid handler. Its advanced head technology enables delivery of evaporation temperatures up to 80 degrees Celsius for faster solvent evaporation rates. If required, the system has the option to be fitted with ducted fan fume extraction.
Operated via an intuitive graphical color LED touchscreen, software features include up to five stored alphanumerically named programs and multi-step evaporation programs. This functionality combined with real-time run displays showing actual gas temperature, gas flow rate, and stage height means the Ultravap Levante puts the user in full control of the evaporation process. A removable acrylic splash guard safeguards the operator and also ensures efficient removal of the solvent vapor from the evaporation table.
The Ultravap Levante is supplied with an evaporator head of the user’s choice, which may be interchanged quickly and easily with a head of a different pattern as workflow demands. The precision engineered mechanism uses a standard ANSI/SLAS plate nest to accept most microplate formats and tube racks. It can accommodate tubes up to 50mm in height in a variety of configurations to allow the use of 2 Dram vials, 1.5ml HPLC vials, bar-coded tubes in racks, and many other common formats. Evaporator heads are available for efficient dry down of 24-, 48-, 96- and 384-well microplates at temperatures up to 80 degrees Celsius.
The Ultravap Levante can be operated from both a gas cylinder and an in-house supply of nitrogen or clean dry air. The blow-down evaporation technique is well proven for efficiently removing chromatography solvents such as dichloromethane, acetonitrile, methanol, and hexane.
