The Perkin-Elmer Lambda™ 25/35/45 UV/Visible Spectrophotometers increase productivity by mimicking the QA workflow to generate high-quality results the first time, every time. And that’s exactly what the user needs in a busy laboratory when the pressure’s on and it’s the user's job to keep the results flowing. LAMBDA systems are easy to operate and deliver results the user can trust with the minimum of operator training. With Perkin-Elmer's complete range of LAMBDA systems it’s easy to develop simple, robust methods and ensure they’re followed without mistakes. And, whichever LAMBDA system is choosen, the user's day-to-day UV/Vis analyses will be faster, simpler and more dependable than ever before.

UV WinLab™ software works the way the user works, guiding the user through a step-by-step process that simplifies analysis from sample entry to report generation, eliminating costly mistakes and delivering rapid results. The user can rely on Perkin-Elmer's proven technology to deliver consistently high-quality results over the lifetime of the system, and the user can confirm those results with Perkin-Elmer's extensive suite of Instrument Performance Verification (IPV) tests. For FDA-regulated industries, the Enhanced Security™ (ES) version of UV WinLab integrates seamless 21 CFR Part 11 technical compliance without slowing the user down.

BLE1900401

The NanoDrop® ND-1000 UV-Vis Spectrophotometer enables highly accurate analyses of 1 ul samples with remarkable reproducibility.

The full spectrum (220nm-750nm) spectrophotometer utilizes a patented sample retention technology that employs surface tension alone to hold the sample in place. This eliminates the need for cumbersome cuvettes and other sample containment devices and allows for clean up in seconds.

You’ll find yourself making fewer dilutions and taking more readings than ever before, essentially becoming a more quantitative laboratory.

In addition, the NanoDrop 1000 Spectrophotometer has the capability to measure highly concentrated samples without dilution (50X higher concentration than the samples measured by a standard cuvette spectrophotometer).

NanoDrop® ND-1000 UV-Vis Spectrophotometer Benefits:

Small Samples - Designed for 1 ul samples
Large dynamic range - Measures 2-3700 ng/ul (dsDNA) on a single sample. No need to change out cuvettes or caps.
High absorbance capability - 50 times that of traditional spectrophotometers
No Dilutions for most samples
No extra costs for consumables
Full Spectrum (220-750nm)
10 second measurement time
No cuvettes or capillaries
Sample is recoverable
Small size (size of a tissue box)
Easy set up (plug and play)

NanoDrop® ND-1000 UV-Vis Spectrophotometer Applications:

Nucleic acid concentration and purity of nucleic acid samples up to 3700 ng/ul (dsDNA) without dilution
Fluorescent dye labeling density of nucleic acid microarray samples
Purified protein analysis (A280) up to 100 mg/ml (BSA)
Expanded spectrum measurement and quantitation of fluorescent dye labeled proteins, conjugates, and metalloproteins
Bradford Assay analysis of protein
BCA Assay analysis of protein
Lowry Assay analysis of protein
Pierce Protein 660 nm Protein Assay
Cell density measurements

The DAWN® HELEOS® II is the premier Multi-Angle static Light Scattering (MALS) detector for absolute characterization of the molar mass and size of macromolecules and nanoparticles in solution. The DAWN offers the highest sensitivity, the widest range of molecular weight, size and concentration, and the largest selection of configurations and optional modules for enhanced capabilities.

The DAWN is most often used in conjunction with Gel Permeation Chromatography (GPC-MALS) or Size Exclusion Chromatography (SEC-MALS) or Field-Flow Fractionation (FFF-MALS) to determine distributions of mass, size and composition independent of column calibration by reference standards.

Included with each DAWN is a copy of ASTRA, the most versatile software package available for analysis of online multi-angle and dynamic light scattering.
