Porvair Sciences has launched its new generation Ultravap Levante nitrogen blowdown sample evaporator.
The second generation system offers the many benefits associated with the company’s flagship Ultravap Mistral in an affordable, easy-to-use package. The single microplate evaporator is designed to meet the needs of most chromatography laboratories whilst 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. Advanced head technology enables delivery of evaporation temperatures up to 80°C for faster solvent evaporation rates. It can also be fitted with optional ducted fan fume extraction.
Operated via an intuitive graphical colour LED touchscreen, software features include up to five stored alphanumerically named programmes and multi-step evaporation programmes. Real-time run displays show actual gas temperature, gas flow rate and stage height. A removable acrylic splash guard safeguards the operator whilst ensuring efficient removal of the solvent vapour from the evaporation table.
The instrument is supplied with a user-selected evaporator head, which can be easily interchanged according to 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 two 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°C
The Ultravap Levante can be operated using a gas cylinder or 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.
