A lyophilizer (freeze dryer) vacuum pump is a critical component in the operation of a freeze dryer or lyophilizer. It is responsible for creating the vacuum necessary to carry out the lyophilization process.

The oil sealed rotary vane vacuum pump working principle is relying on the centrifugal force and the tension of the spring to keep the top of the rotary vane in contact with the inner wall of the pump chamber, the rotation of the rotor drives the rotary vane to slide along the inner wall of the pump chamber.

What is an electron microscope? An Electron microscope is an advanced scientific instrument that uses electrons to produce highly magnified images of objects at a very high resolution. Unlike light microscopes, which use photons of light to produce an image, electron microscopes use a beam of electrons to illuminate the object being studied. The two main types of electron microscopes are transmission electron microscopes (TEM) and scanning electron microscopes (SEM). TEMs use a beam of electrons to pass through a thin sample, producing an image of the internal structure of the sample. SEMs, on the other hand, use a beam of electrons to scan the surface of a sample, producing a highly detailed, three-dimensional image. Electron microscopes have revolutionized many fields of science, including biology, materials science, and nanotechnology, allowing scientists to study the structure and properties of materials and biological samples at the atomic and molecular levels. They are w

The turbomolecular pump was first invented in 1957, and companies in various countries have put their products on the market and have been developed and popularized.

A clean vacuum environment has always been the ideal vacuum environment pursued by scientists and enterprises. Since the creation of a vacuum environment, people have tried to use different means to achieve the effect of a clean vacuum. Up to now, clean vacuum obtaining equipment has developed to condensate vacuum pumps, plunger vacuum pumps, claw vacuum pumps, scroll vacuum pumps, and diaphragm vacuum pumps.

CF vacuum flanges are all-metal sealing methods and are widely used in ultra-high vacuum systems. KF vacuum flanges are a quick-release method used in vacuum systems. ISO flanges, as the diameter of ISO general pipe is more than 50mm (2 inches), which can be used in various applications from atmospheric pressure to high vacuum, are often assembled and disassembled. more information and images at https://www.bowahvacuum.com
