This article lists several commonly used fluorescence spectrophotometer prices in New York, followed by a detailed introduction to the principle, use, and price of the 721 spectrophotometer.
Fluorescence spectrophotometer F93 Mall price: ¥14000product description:
The series of fluorescence spectrophotometers use high-intensity LED cold light source. The emission monochromator adopts 1200-line grating and large-aperture aspheric mirror spectroscopic system. The rich accessories can support the measurement of liquid, solid, powder and film samples. Optional multi-purpose fluorescent sample holder accessories for accurate measurement of high-concentration samples, as well as micro-samples as small as 5μl can be accurately measured, and optional micro-sample accessories and auto-injection accessories for a variety of applications.
F93 fluorescence spectrophotometer is suitable for the determination of visible light region. It can be extended to red-sensitive band detection by using special photomultiplier tube detector. It supports two modes: single machine and online. In the single machine state, the internal microcomputer system provides fluorescence intensity measurement and concentration direct reading. , automatic zero adjustment, automatic deduction of background and other functions. Online status Data collection and analysis can be performed using the universal data software via the serial interface.

·Basic precautions
Do not put expensive oil into low-quality cartridges to avoid wastage. Most pre-filled oil cartridges have the so-called 510 thread. The oil cartridge screws onto a rechargeable battery. Some of these batteries have buttons and some heat up automatically when you pump the oil. Some batteries have multiple temperature settings and some heat up to a preset temperature; these features need to be known in advance.
·Cleaning notes
Use a suitable cleaning tool to clean them, such as activated charcoal or dried tea leaves in a used pipe to absorb the oil. It is important not to use alcohol or other boiling water to clean the pipe, and to wait until it has cooled down completely before cleaning. Otherwise, the hot stem will come into contact with the watery liquid and cause the mouthpiece tenon to loosen, thus shortening the life of the 510 cartridges.
This is what you should be aware of when using 510 cartridges. At the same time, when using 510 cartridges, there are still some vaping tips, for example, when using them, be careful not to suck too hard, will not produce smoke. When you inhale too hard, the smoke is sucked directly into your mouth and not atomized by the atomizer, so gently inhaling is more powerful and gives you a better vaping experience.
