  • Digital lab balance (scale) that can weigh in grams (g) with a capacity (weight limit) of at least 200g and a resolution of at least one-hundredth of a gram (0.01g). Your scale should also have a tare feature and calibration mode.
  • At least one perfumery raw material from each of the following categories: liquid (essential oil or liquid aromachemical), solid (vanillin powder, coumarin powder, Ambroxan flakes), and semi-solid (Benzoin resin, Myrrh Resinoid, Labdanum Absolute)
  • Common solvents (diluents) used in perfume making such as Perfumer’s Alcohol/Specially Denatured Alcohol (SDA-40B), DPG (dipropylene glycol), IPM (isopropyl myristate), TEC (triethyl citrate. These items can easily be purchased online from Saveonscents.com
  • Beakers
  • Transfer pipettes
  • Spoon or lab spatula for dry materials
  • Vials or bottles with lids to store dilutions
  • Labels for your bottled dilutions
  • Lab hotplate or small bowl of dry rice with access to a microwave for melting semi-solid materials
  • Paper towels
  • Wax paper

Suggested vendor for purchasing a lab balance (scale):

We recommend purchasing your lab balance from an online vendor called Old Will Knott Scales. https://www.oldwillknottscales.com

They are a well-respected company with exceptional customer service. We have purchased scales from them for over 20 years and have never had an issue and have been very happy with the high quality of their products and customer support. We have no affiliation with Old Will Knott Scales beyond being long-time happy customers. The scales that both Darren & Emily use are from the MyWeigh iBalance series, but there are more affordable options from the same vendor that meet most of the above requirements.


An inexpensive entry-level battery powered scale available on Amazon that reads at 0.01g with Tare function is available here:



If you are planning on or currently selling your perfumes, please check with your state’s Department of Weights and Measures to see if your state requires that your scale be NTEP Certified (Legal for Trade). Some states require this and some do not depending on the industries regulated by the Department of Weights and Measures in your state. Old Will Knott Scales offers scales that are NTEP Certified if it is required by your state.
