Hi all,

 

 

Some of the students in our biochemistry use a sonicator (Fisher Scientific Model 100 Ultrasonic Dismembrator).  This sonicator emits a high-pitched sound.  I know that in some labs, people wear ear muffs when using the sonicator.  I think it would be the safest thing if our students also had ear muffs to wear when using this instrument.  Any recommendation for an appropriate lab-safety type of earmuff?

 

Thanks,

 

Wayne
