The low. setting is 4 power magnification and the scope is adjustable up to 12 power magnification. The 50 on the. end means the objective lens is 50mm in diameter. This info is well and good but there is more to it. All. 4-12x 50 scopes are not created equally. The diameter of the scope tube is one factor in how much elevation adjustment the scope has.
Hepatitis A virus can live outside the body for months, depending on the environmental conditions. Hepatitis B virus can survive outside the body at least seven days and still be capable of transmitting infection. Recent studies have shown that hepatitis C virus can survive outside the body and still transmit infection for 16 hours, but not longer than four days.

Re: Norovirus on surfaces. Most viruses do. Colds and flus can really only survive for 48 hours on nonporous surfaces but less for porous surfaces. Some viruses can survive for a long time, like months, but you're unlikely to encounter any of these in your life. Norovirus is the hardiest of the common viruses you might catch, and it can survive from 12 hours to about 14 days.
