Douglas Vapor Batch Plate
The Douglas Vapor Batch Plate is designed for both microbatch and vapor
diffusion (sitting drop) crystallization. It has 96 wells in the center and
several reservoirs around the outside. The reservoirs can be used to
preserve microbatch crystals by preventing drying out of the wells, or they can
be used for simple vapor diffusion experiments where up to 96 wells are
equilibrated against a single precipitant (preliminary experiments suggest that
this method finds more hits in screening experiments than the conventional
method of using the same solution in the reservoir and the drop).
Two versions of the Vapor Batch plate are available: treated (hydrophilic) and untreated (hydrophobic). We recommend the treated hydrophilic version for most applications including screening.
The untreated hydrophobic plates are useful for some optimization experiments and for some detergents and proteins. Experiments dispensed to the treated hydrophilic plates tend form disc shaped drops whilst experiments dispensed to
the untreated hydrophobic plate tend to form rounder taller drops - Please see example drops in image below

Holders are available from Douglas Instruments to provide a regular Linbro or SBS ( i.e. regular 96-well) footprint.
The Douglas Vapor Batch Plate was designed and is manufactured by Douglas Instruments. It can be obtained from Douglas Instruments and from Hampton Research.
Douglas Instruments is running a competition for the best use of the Douglas Vapor Batch Plate.
