![]() The 3D coordinates of individual GNP, SNP, and GNR nanoparticles ( x, y, z) were resolved by fitting the data with 3D point spread functions using a least-cubic algorithm and collation. Single-particle images were then compared with simulation data. Various plasmonic nanoparticles on a glass slide (i.e., gold nanoparticles, GNPs silver nanoparticles, SNPs and gold nanorods, GNRs) were imaged and sliced in the z-direction to a thickness of 10 nm. We will try to match or beat any price from our competitors, so feel free to inquire! Complementary shipping and handling can be applied upon immediate purchase.Augmented three-dimensional (3D) subdiffraction-limited resolution of fluorescence-free single-nanoparticles was achieved with wavelength-dependent enhanced dark-field (EDF) illumination and a least-cubic algorithm. Purchasing our refurbished instruments can save you anywhere from 30% to 90% compared to purchasing brand new. We include customs fees, brokerage, and duties for shipping to the US. Complementary shipping and handling can be applied upon immediate purchase. We have sufficient export experience, including professional packing and proper documentation. You can find all the equipment you need for you lab in our store, as well as mix and match components for your systems. We have a large inventory of equipment, components and parts in stock. If you’ve purchased less-complex equipment from us that you would like to install yourself, we can provide Team Viewer, email, or telephone support for no additional cost. If the instrument is particularly complicated, we highly recommend this service. If you purchase equipment from Spectralab Scientific, we offer installation and familiarization by our service technicians for an additional fee. We will match our warranty duration with our competitors. Do not attempt to repair the equipment or involve a 3rd party without our express permission – this will result in voiding our warranty. Any issues that occur during warranty should be reported immediately, describing the issues in as much detail as possible. Warranty begins from the date your equipment is successfully delivered. If there is ever anything wrong with the equipment, we will replace it. ![]() While your instrument is on warranty, we will provide Email and phone support and troubleshooting if you require assistance. Warranty starts at 3 months, with the option to extend the period. We offer warranty on all refurbished instruments. We are an affordable alternative to many normally expensive business projects. We endeavor to develop strategic partnerships with our clients so that they consider our team as an extension of their employees. We provide value added support and qualification/validation with all our instruments. We are constantly updating our knowledge with the latest technology and information to enable us to deliver the best support in the industry. We have been working with Agilent, Waters, Perkin Elmer, Sciex, Shimadzu, and Thermo instruments for many years. Our team of skilled technicians are experts at fixing analytical instruments. We follow Installation Qualification, Operational Qualification, and Performance Qualification protocols (IQ, PQ and OQ). Our refurbished instruments are tested and repaired to meet factory specifications. The MultiSpec offers the compact design needed for today’s laboratories.The simplified optical design results in consistent and stable measurements. The drive mechanics have been minimized.Including processing time, the full wavelength range spectrum is displayed in approximately 1 second. High-speed 0.1 second measurement in the time course or monitoring mode, making it ideal for on-line processes or stop-flow kinetic assays.An optional pass/fail indicator makes it ideal for any quality control environment. Time course data can be displayed in 2-dimensional or 3-dimensional plots, allowing the user to quickly determine any change in absorbance over the entire wavelength region. ![]() It can perform an array of different quantitative analyses including multiple linear regression, PLS, calibration curves, custom equations, color, kinetics and more. And of course, the software also runs under Windows® 3.1. The MultiSpec-1501 uses powerful PC-based software (Hyper-UV) running under Windows® 95 for control of the instrument. This spectrophotometer brings wavelength scanning into a new era. Just place the sample in the roomy, open sample chamber and click the start button. The MultiSpec-1501, with the newest optical and computer software technology, satisfies the demands of accurate and reproducible results, high-speed productivity and compact size. The energy from the dispersed light is measured almost simultaneously by a highly-sensitive 512 element diode array. The MultiSpec-1501 can acquire spectra over the entire wavelength range in just 100 milliseconds.
