The NanoDrop® ND-1000 is a full spectrum (220-750nm) spectrophotometer that provides scientists with a simple and robust instrument for quantification and evaluation of purity of samples, such as proteins and nucleic acids. The technology is based on...
A spectrophotometer is an instrument that measures that intensity of color in a linear range. Spectrophotometry is a study that involves measurements of light intensity in the visible, near ultra violet and near infrared ranges. Spectrophotometers are used extensively...
Spectrophotometry is a technology that has long been considered mature, and advances in instrumentation tend to focus on fine-tuning the technical details, such as...
1 µL - 2 µL sample. No dilutions. No cuvettes. Less than 5-second measurement.
The NanoDrop™ 2000c Spectrophotometer uses an innovative sample retention system to hold microvolume (1µL -2 µL) samples between two measurement surfaces using the surface tension properties of liquids - no cuvettes needed.
This system allows for path lengths as small a 50 microns so that even very high concentrations of protein can be measured without dilutions. No dilutions mean preparations for sample quantification are easy and cleanup is fast - simply wipe the measurement surfaces with a laboratory wipe.
This video article demonstrates two methods for quantification of microvolume amounts of protein using A280 absorbance readings and the BCA colorimetric assay..
Purchasing a spectrophotometer for your lab can be an overwhelming task. Will you be performing colorimetric assays? Will you need a Monochromator?
The NanoDrop ND-8000 8-sample Spectrophotometer is a high throughput, full-spectrum (220-750 nm) spectrophotometer that can measure 8 individual 1 µl samples with high accuracy and reproducibility. It utilizes the same patented sample retention technology as...
The NanoDrop ND-1000 is a full-spectrum spectrophotometer (UV and visible spectrum, 220-750 nm) for measuring the absorbance of DNA, RNA, proteins and dyes. The newly developed sample retention system allows for measurement of small samples volumes: the sample droplet is held...
The NanoDrop ND-1000 (NanoDrop Technologies) is a full-spectrum (220-750nm) spectrophotometer that can measure 1 ul samples with high accuracy and reproducibility. The spectrophotometer utilizes a patented sample retention technology that employs surface tension alone to hold the sample in place. This eliminates the need...
The ND-1000 from NanoDrop Technology is a computer-controlled spectrophotometer with a small footprint in the lab, designed to measure small quantities of sample (accurate to > 1uL and/or 2ug/mL). The ND-1000 exceeds absorbance capabilities of most spectrophotometers by approximately 50-fold and this increased capacity to read highly concentrated samples reduces the need for dilution...
The NanoDrop Spectrophotometer from NanoDrop Technologies is designed for measuring nucleic acid concentrations in sample volumes of one microliter. The key to this advanced spectrophotometer is its unique sample retention technology that overcomes the need for cuvettes when taking measurements...
