Manufactured from polystyrene (PS) or polymethyl methacrylate (PMMA), they provide accurate, reliable results. Choose PS for determinations above 340nm, and where cost is a concern. When performing assays above 300nm, choose PMMA. (For wavelengths below 300nm, see our UV-cuvettes). These disposable cuvettes are available in macro and semi-micro sizes to accommodate most sample volumes and are compatible with most spectrophotometers and photometers. All BRAND cuvettes are manufactured from scratch-resistant materials, and are grouped by manufacturing mold cavity number to ensure the lowest variation in extinction coefficient....

Plates have 96 wells and are available with 330µL or 400µL well volumes. They are fully compatible with most standard plate readers and BRAND polystyrene and polypropylene microtitration plates are excellent for cell and tissue culture, sample storage, immunological assays, and other applications. Plates have 96 wells and are available with 330µL or 400µL well volumes. They are fully compatible with most standard plate readers and washers.
Both sterile and non-sterile plates are available with rounded, V-shaped, or flat well bottoms to meet the needs of most applications. Sterile, treated plates with hydrophilic surfaces are also available.
Design features help reduce evaporation and contamination. Raised rings around wells simplify sealing with adhesive films and mats. Recessed hollows between wells reduce oversplash. Optional lids are equipped with condensation rings.
Wells are labeled in a standard alpha-numeric pattern to simplify sample identification and are stackable for easy storage. Notched corners facilitate orientation in automated liquid-handling systems.
Non-sterile polypropylene microtitration plates are autoclavable and resistant to a wide variety of chemicals including phenols, chloroform, and DMSO....

Sterile Applications
For sterile applications, such as bacteriological assays, pureGrade™ S plates are sterilized by ß-radiation to ISO 11137 and AAMI pureGrade™ BRANDplates feature untreated surfaces for use in a variety of laboratory tasks, such as homogeneous assays, screening and storage.
Sterile Applications
For sterile applications, such as bacteriological assays, pureGrade™ S plates are sterilized by ß-radiation to ISO 11137 and AAMI guidelines for a SAL of 10-6, meeting the requirements of Ph. Eur. and the USP 29. Plates are DNA, DNase, RNase free, as well as meeting cytotoxic substance levels per DIN EN ISO 10993. Endotoxins are <0.01 eu/ml.
Comprehensive Line
96-well format plates are available in U-bottom, V-bottom, F-bottom and C-bottom well shapes, in transparent, white, black, and transparent bottom versions. 384-well plates are available in both standard and low-volume varieties in transparent, white, black and transparent bottom (standard volume only for transparent bottom), as well as a proprietary UV-transparent version offering enhanced chemical resistance. 1536-well plates are available in transparent, white or black.
Easy Identification
White and black pureGrade™ and pureGrade™ S plates feature grey embossed alphanumeric codes for easy well identification, in addition to the identification of the pureGrade™ surface.
Easy Selection
Find the right BRANDplates multiwell plate either by physical characteristics or application with the interactive BRANDplates selection guide.
Bar Codes
Bar coded plates are available upon request in quantities as small as 5000 plates for pureGrade™ untreated plates, or as few as 1000 for plates with surface treatments. They are printed with a two-color process - white base with black barcode for enhanced legibility....

BRAND's UV-transparent, disposable cuvettes replace expensive, fragile quartz cuvettes and are excellent for DNA, RNA, and protein analysis between 230-900nm. Made from a proprietary polycyclical olefin, they can be used with most polar solvents, acids and alkaline solutions. In addition to the macro and semi-micro sizes, UV-cuvettes are available in ultra-micro sizes that require only 70µL of sample volume. The ultra-micro cuvettes are also available individually-wrapped and independently-certified DNA-, DNase-, RNase-free for an extra degree of sample protection.
