Transparent Microplates

384-well Krystal™ black and white

The Krystal 384-well microplate range incorporates novel square wells with a large liquid capacity of 120µl per well, increasing the achievable sensitivity of most HTS assays.

Using a proprietary manufacturing technique, the Krystal 384 offers market leading plate flatness (+/- 0.1mm tolerance) that translates into a significant increase in measurement precision and elimination of read errors when performing cell based assays using fluorescent or luminescent imaging. All tissue-culture treated plates are supplied lidded and sterile, in individual bags.

• Opaque walls to prevent well-towell crosstalk
• Clear plate bottom permits direct microscopic viewing
• Thickness of bottom 0.40mm
• For use with top or bottom reading instruments
• Maintaining the standard ANSI/SBS format
• Well volume of 120µl
• Constructed from ultra pure grade polystyrene

Krystal™ 384-well glass bottom plates

Manufactured for whole-plate CCD imaging and laser detection applications, Krystal glass bottom plates consist of a polystyrene upper part and a clear borosilicate glass sheet fixed to the base with a proprietary adhesive. This process results in consistent flatness of the base and gives improved light transmission whilst maintaining a flat optical plane for growing cells. The nominal cut-off wavelength of 335nm allows most fluorescence assays to be excited or read through the glass bottom. All plates are supplied lidded.

• 175µm glass thickness
• +/- 15µm flatness across base
• 335nm UV optical cut-off
• Industry-standard well layout
• Very low autofluorescence
• High degree of planar flatness
• Biocompatible adhesive
• Resistant to alcohol, DMSO and PBS
• Robot friendly
• Manufactured to ANSI/SBS specification

Krystal UV clear bottomed microplates

Recently, scientists have begun using assay chemistries which require excitation or detection wavelengths in the far UV region, below 350nm. To enable our customers to develop assays in this area, Porvair Sciences has introduced a very high specification range of COP-bottomed, UV-transparent microplates. Precision engineered and assembled, these plates are available in 96- and 384-well black matrix only for the most sensitive UV range fluorescence assays using whole-plate imaging or confocal microscopy.

• 220nm far UV cut-off
• 384-well black versions
• Industry-standard well layout
• Very low autofluorescence
• High degree of planar flatness
• High chemical resistance to most solvents
• Robot friendly
• Cyclo Olefin Polymer construction with clear base
• Precision engineered to meet ANSI/SBS specification
