CrystalClear Strips

CrystalClear Strips are suitable for both automatic and manual crystallization.   They are particularly useful for screening, since they save space and are economical.  They are also useful for the production of crystals for data collection at synchrotron sources since they are convenient for transportation of crystals.

Droplets (up to 7 microlitres) are dispensed on a shelf on one side of each well.  Around 100 microlitres of solution are placed in the main reservoir.  The strip is sealed with tape.  Losses by evaporation though the body of the strip and the tape are around 0.25% of the reservoir per day, which is comparable to Linbro trays.

There are two versions of the product.  The original version, CCLEAR-D/1, has depressions on the shelves.  This prevents liquids that tend to wet the plastic from running down into the reservoir.  This version should be used for solutions and screens that contain low molecular weight alcohols and detergents.  The newer plain or platform version, CCLEAR-P/1, has a small circular platform on the shelf on which samples are placed.   This gives improved viewing but is not suitable for solutions containing alcohols etc.

CrystalClear Strips were designed and are manufactured by Douglas Instruments.   They can be obtained from Douglas Instruments and Hampton Research.

TIP: - put normal office tape on each strip to prevent evaporation temporarily. Replace with CrystalClear tape when the experiment is finished.

Douglas Instruments is running a competition for the best use of the Crystal Clear Strips or the Douglas Vapor Batch Plate.

If you have any comments about the design of the Crystal Clear Strips, please contact patrick at douglas.co.uk   For example, would you prefer a well with a smaller volume (on the depression version of the product)?
