The external dimensions for thomas no.
Zetasizer nano series and zetasizer µv zen0040 disposable, solvent resistant micro cuvette, for size Determines only the minimum fill volume; It is essential to make sure that you order the cuvette with the correct z dimension. 170 to 2700 nm ‘z’ dimension:
Spectrophotometers are instruments used for measuring radiant or light energy, traditionally with a quartz cuvette.
It is very easy to calculate the volume of any cuvette. Transmission difference between different cuvettes: 2mag small volume & cuvette stirring drives email: The sve175 is a small volume electrode for use with small sample volumes to determine zeta potential.
We have dimension charts on each product page that show you exactly what figures you need.
The cuvettes will be especially useful in conjunction with the new zetasizer 1000hs and zetasizer 3000hs. The sample volume minimum is approximately 200 microliter. Thomas short, micro, spectrophotometer cells. Ideally suited for measurement at 260 nm, 280 nm and in the visible range.
If not properly chosen the z dimension (light height), the micro cuvettes might well not be compatible and cannot be used.
For size and molecular weight measurements for use with the zetasizer nano and advance series (minimum sample volume s/zs is 12 microlitres, s90/zs90 minimum is 20 microlitres, maximum volume 45 microlitres). Specially designed for photometric determination of proteins, ssdna, rna and oligonucleotides in the uv range. 4 x 10 x 11 mm. Outside dimensions 12.5 x 12.5 x….
Here is the formula that we use:
Small volume & cuvette filter by sort by. Less than 1% (typical transmission curves of synthetic quartz cuvettes were measured empty, thickness 1.25 mm x 2, including surface reflections, measured with a. Can be used with aqueous dispersants. The clear windows for light beams could be very small (i.e.
Standard 10 mm light path.
How we calculate cuvette volume. Spectrosil® far uv quartz window usable range: Sample volumes as small as 70 μl are sufficient. Round top, use round lid.
Common z dimensions are 8.5 mm, 15 mm and 20 mm.
Zen0118 disposable low volume cuvette for size measurement, pack of 100 with 100 caps, minimum volume 50µl, suitable for all systems that measure size at 90 degree scattering angles only. All systems with s/n less than mal500119 need an upgrade to the optics. Small volume 0.9ml and 4 clear windows for fluorescence applications. The ability to measure a sample in a submicro cuvette with the same sensitivity as a 3.5 ml standard cuvette
Inner length x inner width x inner height x 80% = cuvette volume.
2 mm x 5 mm). The cuvette must be filled enough to reach the spectrophotometer beam height. The reduced sample size is especially important in the thermal characterization of dna restriction fragments. The new cuvette allows particle size measurements to be made using sample volumes as low as 0.3ml, and for the zetasizer 1000 and 3000 systems, an insert provided to raise the cuvettes further reduces the required sample volume to 0.1ml.
Why is z dimension important?
Over 30 years experience with inductive and magnetic drive concepts. With and without masking minimum working volume 0.4 ml spectral range as indicated in listings supplied with teflon® cover the nominal working volume of this range represents only 20% of that of the standard cell with the same path length. Sample chamber (w x l x h): The z dimension of a spectroscopy cuvette/cell is the distance from the bottom of the cuvette to the center of the sample window or aperture (the area through which the light passes).
Usable starting from 220 nm.
