Hanging Drop Round Seals

The revolutionary SWISSCI Hanging Drop Crystallisation Plate Seal (UVOP / Non-UVP) comes ready to use with a dust-free protective coating and specialty polymer base. The Seals accommodate up to 3 separate drops of protein and fit the standard 2-drop or 3-drop MRC plates.  The product has a 100 or 40-micron thin layer of UVP specialty polymer developed for compact drop creation and ability to shoot X-ray without any noticeable diffraction. The non-UVP seal comes in 100-micron layer.

The SWISSCI hanging drop seals can be run with individual drops in the 96 positions or 192 drop - or 288 drops.
The volume of the drop is typically between 50 and 100 nanolitres.
The seal covers sit directly over the microwell plate crystallization reagent wells and are closed with a long term resistant closing adhesive which is validated not to ingress into the sample - nor lead to seal corruption. The seal have no adhesive in the well so crystal viewing is optimum.

To remove an individual crystal the seal may be peeled back or simply cut out with a scalpel. The material is very thin although still remaining as a perfect evaporation barrier and can be sliced with a knife very easily.

The seals are produced in a class 100,000 cleanroom environment and guaranteed to be dust and scratch-free.
Optical quality is of the highest level available.
The seals are able to be used in the UV / Non-UVP range thus enabling the user to recognize salt - from protein crystals under the Ultra Violet light source microscope.
