Evaporators (Ultravap™)

Ultravap™ evaporators

Digitally controlled programmable blowdown evaporator system to remove traditional laboratory bottleneck of solvent evaporation from microplates prior to analysis or reconstitution in storage buffer. The evaporators have been designed to be simple to install, operate and maintain. Installation requires only connection to a gas supply or cylinder and mains electricity. Safety of operation is ensured as the CE marked compact units fit into all fume cupboards. Not suitable for high boiling point solvents such as DMSO and water.

Ultravap™ Mistral

The Ultravap Mistral has been designed to allow robots with standard gripper arms to place and remove microplates directly onto the shuttle. In comparison with previous models, the Ultravap Mistral has a 10% smaller footprint, allowing better access and saving valuable bench space.

The evaporation table is able to rise under the control of a stepper motor as the drying process proceeds. This can be programmed at a suitable rate for each solvent type being evaporated. In addition, gas temperature, pressure and flow rate can all be programmed individually and stored in up to thirty multistep programmes on the Ultravap Mistral controller. Each programme allows the table to rise in up to five distinct ramped phases, so that a fast initial drying period can be followed by a gentler final drying phase. The new Ultravap Mistral lends itself to full integration with most robotic liquid handlers, where it is usually located on the right-hand side of the deck. Control commands are sent directly from the robot controller to the Ultravap. These standard commands are listed in the manual, but most robot manufacturers have drivers available to control the Ultravap, making integration a seamless process.

Ultravap™ Levante

The Ultravap Levante is the latest in Porvair Sciences’ popular series of nitrogen blow-down sample concentrators and evaporators. Using technology from the Ultravap Mistral series of robot-ready, integration compatible evaporators they have re-designed the classic single plate evaporator to meet the needs of the modern laboratory.

Now you get full-colour touch screen graphic displays, an integrated auto-ranging power supply and built-in fume venting. Combined with real-time run displays showing actual gas temperature, gas flow rate and stage height the Ultravap Levante puts you more in control of the evaporation process. Offering multi-step ramped programming with full alphanumeric program naming, the Levante is the state-of-the-art standalone evaporator.

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 80mm 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 made to match these formats in 24-, 48-, 96- and 384-well configurations. The unique 96-well spiral needle head, which creates a vortex in certain plates to speed up evaporation, can also be used on the Ultravap Levante.
