AdministratorWhat are disposable cuvettes?
Disposable UV Cuvette … Disposable cuvettes are ideal for analysis of DNA, RNA and proteins, replacing expensive fragile quartz cuvettes. They eliminate the tedious chore of cleaning quartz cuvettes and eliminate cross-contamination risk.
Are plastic cuvettes suitable for UV spectroscopy?
All Answers (6) you cannot use plastic cuvettes in UV region. You will experience too much fluctuation of absorbance. Rather used quartz cuvettes, because are stable in that range.
Why reusing of disposable cuvette is not recommended?
In one laboratory, disposable plastic cuvettes were routinely reused by rinsing them with deionized water, followed by an ethanol rinse to help them dry rapidly. The ethanol leached material from the plastic and eventually caused a change in the surface properties of the cuvettes.
What are the different types of cuvette cuvettes?
The four most popular cuvette materials are listed below:
- Optical Glass or Pyrex Glass.
- UV Quartz.
- IR Quartz.
- Sapphire.
How do I choose a cuvette?
It is generally important that cuvettes be as transparent as possible for the wavelengths to be measured so not to limit the available linear range of the photometer. The selection of the equipment necessitates requirements on the cuvette, since it must be compatible with the device.
What are disposable cuvettes made of?
Disposable cuvettes can be used in some laboratories where the beam light is not high enough to affect the absorption tolerance and consistency of the value. Most often Polymethylmethacrylate (PMMA) and Polystyrene (PS) material use to make the plastic cuvettes.
What are the different types of cuvettes?
Why do we use a quartz cuvette instead of the normal plastic or glass cuvette?
Glass cuvettes are used for measurements in the visible range from 320 to 2500 nm. Quartz cuvettes deliver precise results in the whole UV and visible range from 200 to 2500 nm. The smaller the manufacturing tolerance, the better and more repeatable the measurement.
Can you reuse disposable cuvettes?
It is not recommended to wash and reuse plastic disposable cuvettes.
Can you reuse spectrophotometer cuvettes?
Clean cuvettes are the foundation of any photometric measurements. Even plastic cuvettes are disposable and no need to worry about cleaning, the rest of the quartz or glass cuvettes are reusable and require cleaning to avoid cross-contamination.
What is a spectrophotometer cuvettes?
The small cuvettes securely hold substances to study the ability for electromagnetic radiation absorbed or emitted. Spectrophotometer cuvettes are manufactured in a variety of clear materials to support different wavelength range and pathlength requirements.
What is the transmittance range of UV-Cuvette spectrophotometers?
They are produced from either optical polystyrene or UV grade PMMA and include optical windows for optimum transmittance through spectrum range from 340 to 800nm for the optical polystyrene and from… Accessories for BRAND UV-Cuvette Disposable Spectrophotometer/Photometer…

Why choose Disposable cuvettes for DNA analysis?
Disposable cuvettes are ideal for analysis of DNA, RNA and proteins, replacing expensive fragile quartz cuvettes. They eliminate the tedious chore of cleaning quartz cuvettes and eliminate cross-contamination risk.
