Sapphire Optical Windows Perform in Demanding Applications

0

Sapphire Windows manufactured from single crystal sapphire are ideal for demanding applications such as laser systems, where high pressures, high temperatures, high thermal loads, vacuum conditions, scratch/wear resistance, low friction and corrosive atmospheres are important considerations. As a result, they are often used in research, medical, aerospace and military applications. Here are some reasons why.

• Except for diamonds, sapphire is the hardest crystal known to man. On the Mohs scale of hardness, which ranks materials from softest (1) to hardest (10), it is rated 9.

Medical Device Production

It is amazing that modern science has advanced to an era in which we can make replacement hips, joints, insulin pumps, and other medical devices. These devices require precision and must be made under strict conditions. Before these items are used to help someone in a hospital, they are manufactured in a clean room.

What is a clean room? These rooms vary greatly, depending on what they are being used for, but generally speaking it is a controlled environment. These rooms are ranked according to an international standard called ISO 14644 which limits the amount of particulates that can be in a sample of the air within the room.

Cleanroom Pressurization

0

One of the most important aspects of cleanroom design is HVAC and airflow in the room. In addition to incorporating a robust HVAC control system and HEPA filters, many cleanrooms also include pressurization. Positive pressurization is particularly beneficial to rooms that handle sensitive processes.

Air typically flows down from the ceiling through HEPA filters, sweeps the floor and is exhausted through grilles in the wall. The air is then pumped back up to the ceiling where it is sent back through the HVAC units.

Feather Color in Birds

Anyone who knows me, or has read my articles knows that I am passionate about wild birds; and not just because of their colors. There are many birds that lack bright and powerful hues and tints. It is the way nature has designed and used those colors to enhance birds’ survival that evokes my appreciation.

Pigment and the way a feather is constructed determine the color of birds’ feathers. The pigments come from just 3 different groups.

Melanins which produce black, brown, rust and pale yellow
Carotenoids that absorb blue light and turn it into red, orange and bright yellow
Porphyrins which make pink, brown, green and rusty red

Humans, animals and plants all have melanin present in different amounts and for different reasons:

In people, melanin determines the color of our skin, the iris of our eyes and the color of our hair.

Buying Recertified Centrifuges – What You Need To Know

0

Startup clinics, small labs, and hospitals which need of lab centrifuges but have budget constraints usually look to purchase recertified centrifuges as a cost saving alternative. Buying recertified centrifuges is not an easy job. There are some things you need to know to choose the right one.

Used lab centrifuges that those are returned are mostly because of very small defects or are sold off when labs need to purchase a more advanced model. The used equipment is purchased by leading lab equipment suppliers and refurbished before they are recertified and offered for sale.

So what is a clean room? These rooms are controlled environments that have strict standards for temperature, humidity and air cleanliness. The standards for clean rooms vary based on the type of work that is being conducted within the room.

Controlled environments use a host of different devices to ensure cleanliness.
