What is NanoDrop used for?
What is NanoDrop used for?
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.
How does a spectrophotometer work?
How does a Spectrophotometer work? Spectrophotometry is a standard and inexpensive technique to measure light absorption or the amount of chemicals in a solution. It uses a light beam which passes through the sample, and each compound in the solution absorbs or transmits light over a certain wavelength.

What does TruNarc test for?
The TruNarc analyzer easily and quickly tests for over 400 substances, including narcotics, stimulants, depressants, hallucinogens and analgesics. Provides automated, tamper-proof records with scan results, including time-and-date stamps to help expedite prosecution.
What is nano spectrophotometer?
Biolab Nano spectrophotometer is a compact, micro volume UV Visible Spectrophotometer with enhanced sensitivity that can detect samples at 3ng/µl. It gives you fast measurement typically less than 5sec\sample and provides rapid and reproducible results without prior dilution.
What are the parts of a spectrophotometer?
A spectrophotometer consists of four basic components: a light source, a sample holder, a monochromator, and a detector. The monochromator comprises a fixed entrance slit, a dispersing element such as a prism or a diffraction grating, and a moving exit slit.
How do ion scanners work?
The unit detects the deflection of particles once they have been exposed to an electric field. “The speed at which the particles move helps determine the substance of origin.”[1] Once an illegal substance has been “detected” according to the ion scanner, law enforcement seeks (and frequently obtains) a search warrant.
How accurate is TruNarc?
The TruNarc® successfully detected the target drug in 77% of the case samples, and generated reproducible results in 84% of the case samples when the results were compared to the rescans on days two and three.
How does Nano drop work?
Fluorescence measurement The NanoDrop 3300 model allows fluorescence analysis of micro-volume samples. With the arm open, a fluorescent sample is pipetted directly onto the pedestal. After the arm is closed, a sample column is formed and held in place by surface tension during the fluorescence measurement.
What is a Spec 200 Spectrophotometer used for?
The Thermo Scientific SPECTRONIC 200 spectrophotometer is the standard for routine measurements in instructional and analytical laboratories. Designed for simplicity and speed, the SPECTRONIC 200 is a rugged, simple-to-use spectrophotometer that provides quick, easy measurements and years of trouble-free performance.
What is a spectrophotometer used to measure?
“Spectro” refers to the fact that light is dispersed into individual or groups of wavelengths in the electromagnetic spectrum of energy. Some of that energy is in the ultraviolet and visible light range, which certain spectrophotometers can read, while others can measure infrared radiation.
How much does a spectrophotometer cost?
Not every spectrophotometer can measure all types of samples. You may need a model that’s configured to your needs. Pricing for spectrophotometers can vary, but you can expect an entry-level product, such as a portable spectrophotometer, to cost less than $9,000, while the high-end options can reach upward of $28,000.
Why choosethermo scientific UV-Vis Spectrophotometers?
