A French Government-funded study preprint submitted Tuesday and authored by Dr. Didier Raoult has confirmed that Pfizer Inc.’s COVID-19 injection contains 5,160 nanograms (ng) of contamination DNA per dose, exceeding the FDA and EMA’s regulatory safety limit of 10 ng per dose by 516 times.

This alarming figure supports this website’s previous reports, as multiple studies analyzing different batches now suggest the jab’s DNA contamination may be more widespread than previously acknowledged.

In the new study, the contamination was first measured at 216 ng per dose, but after treatment with Triton-X-100—a chemical used to release trapped DNA—the levels surged by 24 times, revealing the staggering amount of residual DNA in the final product.

“Vaccine plasmid DNA quantification using the Qubit fluorometer on a vaccine vial showed it was 216 ng/dose on average and approximately 24 times greater, reaching 5,160 ng/dose on average, after treatment with Triton-X-100,” Dr. Raoult explained.

The study also identifies sequences linked to the vaccine’s manufacturing process, including an SV40 initiation factor.

This component, used to aid replication in laboratory settings, underscores failures in the purification process.

TOPSFLO is the only manufacturer in China that can provide diaphragm pumps, micro gear pumps, and brushless dc centrifugal pumps for IVD systems at the same time:

Micro brushless dc centrifugal pumps are usually used in IVD, circulating constant temperature systems to control the temperature of in vitro diagnostic kits, microplate readers, fluorometers, etc.;

Micro diaphragm pumps are the most widely used pumps in IVD instruments, especially in waste liquid systems, to clean and remove waste liquid from reaction cups and pipes. In this step, a diaphragm liquid pump can be used to directly pump out waste liquid; or a micro vacuum pump can be used to vacuum a closed container to indirectly suck out waste liquid in the instrument.

Micro gear pumps are often used to clean the inner wall of needles with high pipeline resistance. The cleaning effect of the needle is strongly related to the internal roughness of the needle, the design of the inner wall needle tube, and more importantly, the high pressure provided by the gear pump. High-pressure flushing of the inner wall can ensure sufficient cleaning flow under high resistance.

On November 11, let's meet in Düsseldorf, Germany!

The filters is the key to successful fluorescence microscopy

The terminology applied to fluorescence filters has become a jumble as a result of various initials utilized by different manufacturers to identify their filters. In this discussion, we attempt to make some order of this confusing terminology. Basically there are three categories of filters to be sorted out: exciter filters, barrier filters and dichromatic beamsplitters (dichroic mirrors) that are usually combined to produce a filter cube similar to the one illustrated in Figure 1. Proper selection of filters is the key to successful fluorescence microscopy Red Excitation Filter Sets.

Exciter filters permit only selected wavelengths from the illuminator to pass through on the way toward the specimen. Barrier filters are filters which are designed to suppress or block (absorb) the excitation wavelengths and permit only selected emission wavelengths to pass toward the eye or other detector. Dichromatic beamsplitters (dichroic mirrors) are specialized filters which are designed to efficiently reflect excitation wavelengths and pass emission wavelengths. They are used in reflected light fluorescence illuminators and are positioned in the light path after the exciter filter but before the barrier filter. Dichromatic beamsplitters are oriented at a 45 degree angle to the light passing through the excitation filter and at a 45 degree angle to the barrier filter as illustrated in Figure 1. Filter curves (spectra) show the percentage of transmission (or the logarithm of percentage) as the vertical axis and the wavelengths as the horizontal axis.

Fluorescence filters were formerly almost exclusively made of colored glass or colored gelatin sandwiched between glass. As a result of more sophisticated filter technology, interference filters have been developed that consist of dielectric coatings

dichroic beamsplitter

(of varied refractive indices and reflectivity) on glass. These filters are designed to pass or reject wavelengths of light with great selectivity and high transmission. Most of today's exciter filters are the interference type; some barrier filters are also, for special needs, the interference type. Dichromatic beamsplitters are specialized interference filters. Sometimes short pass filters (SP) and long pass (LP) filters are combined to narrow the band of wavelengths passing through such a combination.

Spectrophotometer- A Complete Guide

Spectrophotometer is laboratory equipment which is primary used to study the wave nature of light like wavelength, refractive index and intensity of light. This apparatus is regularly used in field of Physics, molecular biology, chemistry and biochemistry. The light energy depends on lambda, and it can be extend up to specific range.

The working principle of Spectrophotometer:

Spectrophotometer breaks the monochromatic source of light (sodium lamp) into two spectral components, digitize the signal as a function of wavelength, and read it out and display it via a computer. In the first step, beam of light is passed through a fiber optic cable into the spectrometer through an entrance slit, which is a narrow aperture. The slit vignettes the light as it enters the spectrometer and then divergent light collimated by a concave mirror and directed onto a grating.

The types of Spectrophotometer:

Lab equipments manufacturers who have expertise in scientific laboratory supplies, they manufacture, sale and distribute several types of Spectrophotometer to school, colleges and research institutes.  If you are looking for the best range of Spectrophotometer then contact to the leading Spectrophotometer Manufacturer, dealer, supplier and distributor. In this article, we will describe 12 types of Spectrophotometer

1-Atomic Absorption Spectrophotometer: Atomic Absorption Spectrophotometer includes a flame burner to atomize the sample like a monochromatic, and a photon detector. This apparatus is equipped with a turret or fixed lamp socket that can hold multiple lamps.

2- Double beam Spectrophotometer: In this apparatus, reference beam and sample beam is passed through the apparatus and it has two detectors that allow the two beams to be measured at one time.

3- Infrared Spectrophotometer- It is an analytical instrument used to identify materials including organic polymers. The device records the relative amount of energy as a function of the wavelength/frequency of the infrared radiation when it passes through a sample.

4- Single Beam Spectrophotometer- A single beam spectrophotometer utilizes one beam of light that passes through the sample and the intensity of the light reflected from a reference is measured without the sample.

5- Spectrofluorometer- The device is designed to detect and quantify fluorophores. When fluorescent molecules are passed through the device, then it absorbs photons at a characteristic wavelength.

6- UV VIS NIR Spectrophotometer- Using specific wave length (between 135 to 3300nm), the device measures material’s reflection or transmission. This device is ideal in fields such as chemistry, materials science, semiconductors, and forensic examination, and in clinical applications.

How to buy the best spectrophotometer:

When it comes to purchasing the best Spectrophotometer, then always contact to trusted scientific laboratory supplies. A leading lab equipment manufacturers, dealers and distributors use their skill efficiently to build the finest spectrophotometer. Following are the simple guide that will help you to choose the correct spectrophotometer for any experiment.

·         Make sure that two parallel windows are polished and if a researcher is using a fluorometer, than all four optical windows need to be polished.

·         Make sure material the cutter is made out of is very good quality. For researchers working in the UV range, they need a special UV quartz that can transmit from 190-340 nm. The most common range that scientists work in is the visible or VIS range which is from 340-2,000 nm.

·         It also matter that which type of light path you are choosing.  Light paths can range from very small, ex. 0.01 mm, up to 200 mm. If the researches have a large sample then a 10 mm light path is the industry standard.

Clearly imaging single fluorescent molecules.

Epifluorescence microscopes are a commonly used tool for studying specimens. Improved specificity and contrast provided by the application of fluorescence to the field of microscopy has stimulated the advancement of various discoveries in the biosciences.

In 1843, George Gabriel Stokes described fluorescence as being characterized by the wavelength of an emitted light that is longer than the wavelength of the exciting light.

This discovery led to the invention of the epifluorescence microscope, now a ubiquitous instrument in biological and medical laboratories.

The high contrast and specificity of the images produced have allowed for the increased understanding of cell structures, the location, and dynamics of gene expression and distinct interactions at a molecular level within the cell.

Epifluorescence illumination or epi-illumination

Epifluorescence illumination or epi-illumination is the specific arrangement of these optical components that allow for the illumination of the specimen from above. The objective lens acts as both the source of light which excites the fluorophore and the element of the microscope that collects the emission filter in fluorescence microscopy .

In comparison to other forms of fluorescence microscopy, epifluorescence illumination has the advantage of only requiring a small amount of emitted light to be blocked.

Though this approach means that the excitation light and emission light overlap, the dichroic mirror efficiently separates the excitation from the emission.

The combination of an excitation filter, dichroic mirror and barrier filter in the filter cubes means that only one photon in 10,000 of the wrong excitation wavelength to the specimen passes, with a similar amount for the emission light. This high ratio is important for clearly imaging single fluorescent molecules.

Terminology:

· Fluorophore: A chemical compound that fluoresces by emitting light upon excitation.

· Photon: A fundamental particle of visible light.

· Ground state: The normal, non-excited state of a molecule.

· Excited state: Electrons can move to a higher energy level by absorbing light, therefore achieving an excited state emission filter fluorescence .
