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.

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.
