Krystal™ Transparent Microplates

Krystal™ Glass Bottom (Schott) Microplates

The latest Krystal™ Glass Bottom plates combine the advantageous optical properties of the industry-leading cover glass technology with the versatility of a microplate. These glass bottom plates offer high optical quality, thermal stability, chemical resistance, and low autofluorescence to suit a wide range of samples for accurate and reliable light and fluorescence readings.

The Krystal™ glass bottom plate range demonstrate higher performance than standard polystyrene plates for fluorescence assays, luminescence detection, scintillation counting and high-resolution microscopy using confocal imaging.

• Low background, low birefringence & low autofluorescence 
• Available in 50 µm, 175 µm thicknesses
• Available in 24-, 96- and 384-well formats 
• Manufactured to SBS/ANSI standards

Special thickness of 170 µm tolerance of +/- 5 µm is also available for high sensitivity applications. 

384-well Krystal™ black and white

The Krystal™ 384-well microplate range incorporates novel square wells with a large liquid capacity of 120 µl 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
