Blowdown Evaporators and Accessories

Porvair evaporators are designed to remove the traditional laboratory ‘bottleneck’ of solvent evaporation from microplates prior to analysis or reconstitution in storage buffer.  These evaporators give significant throughput advantages to laboratories looking to optimize microplate sample preparation productivity.  Faster than centrifugal evaporation, significant increases in sample throughput are achieved through advanced evaporator head technology and an innovative manifold design, which directly injects heated nitrogen into each individual well of the microplate simultaneously.  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 solvents such as DMSO and water.

Both MiniVap and UltraVap may be operated with a supply of clean, dry compressed air in place of nitrogen, if the chemistry allows.  An in-line gas filter must be used in this case.

Mat Capper

Cap Mat Sealing Equipment

We have the Mat Capper, for those smaller labs that don't mind capping their cap mats with brut strength, or the AutoCapper that automatically tightly seals any size storage or assay plate with the push of a button.

Heat Sealing Equipment and Accessories

For those labs that require to heat seal a single plate at a time, the MiniSeal II is the way to go.  For the high-throughput lab, you will definitely appreciate the robust automated Ultraseal Pro that will heat seal six plates per minute with a multitude of sealing film types.

Biological samples commonly contain proteins that interfere with downstream applications.  The P3 plate uses the CRASH method, in which the protein is denatured with acetronitrile and the flocculant filtered out, allowing 96 samples to be handled at one time. 

The Protein Precipitation Plate, P3, is based on the industry standard MicroLute™ format, but without the chromatographic sorbent.  Protein ‘crashes’ out of solution and precipitates directly in each well when acetonitrile is added, thus solving all common problems associated with the CRASH technique of protein clean-up.

The novel dual frit, hydrophobically treated matrix means that there is no ‘wetting out’ and leakage of the sample through the plate before the application of vacuum.  P3 is now commonly used as the protein precipitation plate of choice in many major pharmaceutical companies.
