Our shipping costs are “Live Rates” – that is, when you put in your zip code, our website requests the current rates from USPS and UPS to ship from our fulfilment center in Denver, Colorado to you.

The cost you see is the cost we pay to ship your items, we do not charge any overhead. We apologize for not being able to offer lower-cost shipping than what USPS and UPS charge us. Small businesses like ours do not have the ability to create our own shipping fleet like some of the larger booksellers.

Quick Tips for Reading a Mercury Thermometer

  • Hold thermometer between your finger and thumb near the glass top (called the expansion chamber), opposite the spherical base where the silver tip is located.
  • Shake it down. With a flick of your wrist, shake thermometer in a downward motion, toward the spherical base, so the mercury can settle before measurement begins. This is especially important prior to first use.
  • Place thermometer in the designated area. Keep in mind that it may take 2-4 minutes to read the proper temperature when using a mercury thermometer. *Note: Although thermometer arrives sterilized, be sure to clean before each use.
  • Remove thermometer and look for the temperature (°C or °F) in the scale lines etched along the capillary tube.
  • Mercury Thermometer InstructionsHow to locate the mercury: Look for the bubble above the silver tip. As you rotate the thermometer, the thin line that travels from the spherical base through the capillary tube gradually becomes visible. Rotate until you can see the mercury line.

They are manufactured and imported from India. This is due to FDA regulations and restrictions on the production of mercury thermometers in the US.

My Heart Sound Recorder Lecture Series download is missing slides or looks jumbled. Can you help?

The Heart Sound Recorder Lecture Series features text animations to make the show more enticing to watch. The slides have timed animations that play as the presentation plays.

PowerPoint files have two modes: Edit and Play. In Edit mode, the animations won’t play and sometimes cause overlapping text and this is why your slides may appear blank and/or jumbled.

To play the presentation as it was intended, first, unzip the download (using the instructions on the right side of this page), open either file in PowerPoint, select “Slide Show” on the PowerPoint menu bar, and click “Play From Start”. Use the left/right arrow keys or your mouse button to advance the slides. You can also edit the slideshow to play through automatically by changing the animation settings to suit your needs.
