Introduction
Porvair Sciences Limited has introduced the compact, stand-alone blow down sample concentrator, to
allow evaporation of solvents from microplates in minutes, rather than hours.
The instrument eliminates the traditional “bottleneck” of solvent evaporation prior to analysis or
reconstitution in buffer. It has been designed to be used with ANSI/SBS format 96 well plates
(conforming to the standards noted below). The instrument when fitted with compatible straight or
spiral needle heads, which offers improved drying efficiency, can be used with 96well plates. It can
optionally be supplied with a 24 well straight needle head to allow evaporation of samples stored in
standard 3.5ml (Ø13.75mm) glass vials when used in conjunction with a suitable carrier plate. A
polypropylene adaptor block designed to hold 48 standard 1.5ml HPLC vials (Chromacol/Agilent type)
is available with a matching 48 well head with straight needles. All evaporator heads are easily
interchangeable.
The samples concentrator blows heated gas (typically Nitrogen) into the wells and will accommodate
both deep and shallow well plates. The location of the needle array is fixed. The platform containing
the well plate can be manually elevated to suit well plate dimensions and to optimise dry-down of
samples.
The concentrator has been configured to be simple to install, operate and maintain. Installation requires
connection to a gas supply and an electrical supply. Safe operation is ensured as the CE marked unit
fits into fume cupboards, or may be integrated into a dedicated fume extraction unit.
