An autoclave uses high-pressured steam that reaches extremely high temperatures. Here's how it works: First, the air is let out of the chamber, creating a super low-pressure environment within. The reason steam is used is that the device must reach such high temperatures. Dry air is very ineffective at transferring heat, but saturated air ...

Drying, dissolving, and pipeting RNA. RNA can be dried briefly at +37°C or in a vacuum oven. When working with RNA, place all samples on ice. For the reasons mentioned above, RNA is very susceptible to degradation when left at room temperature. Dissolve RNA by adding RNase-free buffer or water, then standing the tube on ice for 15 minutes.

OOA prepregs ensure even resin distribution, avoiding the dry spots and resin-rich pockets common with infusion processes. Also, OOA prepregs can be cured at lower pressures and temperatures (vacuum pressure vs. a typical autoclave pressure of 85 psi and cure at 200°F/93°C or 250°F/121°C vs. a traditional 350°F/ 177°C autoclave cure).

An autoclave is an important part of any laboratory. First invented in 1879 by Charles Chamberland, the machine uses steam to cleanse and sterilize the contents. Microorganisms, or microbes, require food, moisture, and the right temperature to multiply and survive. If you cannot starve them or dry them out, heat is the only way to kill them.

1. First we remove the air. How? By use of a vacuum pump, the Class B autoclave uses vacuum pulses to extract the air in the autoclave chamber. This process is able to remove more than 99% of the air inside the chamber. Let's say we are going to use three pulses to extract the air. The first pulse will extract about 80% of the air, leaving 20%.
