Plastik küvetler

The LABSOLUTE® disposable cuvettes for the VIS and UV range feature optimised photometric properties and high transparence thanks to modern manufacturing methods. Furthermore, you benefit from the fact that all cuvettes within one packing unit are sorted according to their numbered cavities of origin. Consequently, you receive technically identical cuvettes which prevent deviations in extinction coefficient values. Supplied in practical, reclosable styrofoam racks.

• Increased heat transfer thanks to optimized form and small wall thickness
• Recessed measuring fields: reduce risk of scratching by the cuvette holder
• Arrow marker points to transmission direction
• Path length: 10 mm
• Outer dimensions (W x H x D): 12.5 x 45 x 12.5 mm

Aksesuarlar Accessories for standard and semi-micro cuvettes

Disposable cuvettes for spectroscopy, in optical-quality PS and UV grade PMMA with optical windows for optimum transmittance when using wavelengths from 340nm to 800nm (PS) and from 280nm to 800nm (PMMA). Moulding and quality control determine the reproducibility of cuvettes. Kartell cuvettes are strictly controlled and varations should be within the range ±1% absorption. This is the vital when batch analysis is being undertaken.

For photometric determination of proteins, ssDNA, dsDNA, RNA and oligonucleotides in the UV range. Sample volumes as small as 70 µl are sufficient.

• Usable for wavelengths from 230 nm
• For measurements at 260 nm, 280 nm and in the visible range
• Individually wrapped cuvettes are free of DNase, DNA and RNase
• Grouped by mold cavity number

Scope of supply: 100 netidentical cuvettes in styrofoam box with a resealable cover

The Eppendorf^® Vis Cuvettes are disposable cuvettes made of clear plastic with a light transmission of 300 nm to 900 nm. They are the perfect tool for applications outside of the UV range, for example, colorimetric protein assays (Bradford, Lowry, etc.), determining of the optical density of bacterial cultures (OD600 methods), kinetic and fluorescence measurements. Based on the volume you would like to measure, you can select semi-micro or macro cuvette.
