The model for each tuning fork represents the vibrational frequency measured in cycles per second (cps) or Hertz. For example, the C128 vibrates at 128 Hertz or 128 cycles per second.

As the frequency decreases, the tuning fork's arms must be increased in length. In order to keep the size of the instrument manageable, weights are added to the C128 and C256 frequencies. Without them, these two models would have to be considerably larger.

Tuning forks are used to conduct hearing and neurological vibratory tests. The C128 and C256 forks are generally used for the neurological tests, while hearing tests are often conducted using the higher frequency forks.

The answer to this question depends upon the application. For basic reflex assessment, the Taylor hammer is the most popular. The pointed end of the handle can be used to elicit cutaneous reflexes, and the triangular rubber head is used for testing joint reflexes and bone fractures. The Wartenberg Pinwheel tests nerve reactions as it glides across the skin. It is designed for evaluation of cutaneous sensory and pain perception. The Babinski Hammer is designed for testing reflexes and is equipped with a pointed needle in the handle and a rubber head for reflex reaction.

All laryngoscope blades and laryngoscope sets are supplied with complete instructions for use that outline the sterilization processes available.

No, but they are able to be sterilized.

The answer to this question depends on the application. EMS professionals seem to prefer Macintosh while Anesthesiologists tend to prefer Miller.

The answer to both is a qualified yes! ADC blades and handles conform to ISO 7376 and ASTM F965. ADC blades and handles will be compatible with any manufacturer's brand that conforms to these standards. However, standard illumination components are not compatible with fiber optic components and visa-versa.
