FrameStar® 384 Well Plates
Round 96 Deep Well Storage Plates for use with Magnetic Separators
Cryotubes and Cryoracks
Low Binding Products
1.0 ml square wells, pyramid flat bottom, clear polystyrene
Available in the following colours
This plate has a unique shape of the well bottom with a very flat central part. The pyramid shape allows for a lower dead volume when used in automation. Centrifugation leads to a pellet in the central part of the well rather than a corner.

We are offering the plate in clear, black and white polystyrene while clear plates are suitable for optical applications including imaging.
The pyramid bottom shape results in a very flat optical window that shows good transmission for wavelengths above 310 nm.

The plates base is clear from around 340 nm so would not interfere with optical density reading which are usually performed around 600 nm. The high background below 340 nm would preclude their use in DNA or protein work in the UV range.
The centre of the pyramid shape well bottom is very flat, so absorbance measurements would not be compromised.

Most readers measure absorbance by passing light directly through the sample either bottom to top or top to bottom. The clear plates are suitable for both top and bottom reading modes, while black and white plates can only be used for top reading mode.
This plate is available with linear Code 128-format barcodes to aid identification and traceability for your samples. To order your plates with barcodes, simply add /SBC to the end of the ordering code for Standard Single Barcoding, /DBC for Standard Double Barcoding, /TBC for Standard Triple Barcoding, or /QBC for Standard Quadruple Barcoding (see Barcoding for more details).
