Frequently asked questions
How accurate is the Dropometer compared to a traditional lab goniometer?
In peer-reviewed testing against a Krüss DSA100E, the Dropometer matched the commercial instrument within about 1 degree on static contact angles and 2 to 3 degrees on advancing and receding angles. Published sessile contact angle accuracy is 0.35 degrees.
How much does the Dropometer cost?
The Dropometer flagship starts at US$4,990. Add-ons range from US$250 to US$2,495, with every price listed in the FAQ on the Dropometer page. The Education Kit is US$999 per unit.
Do you accept purchase orders, and what are the payment terms?
Yes, we accept purchase orders. Quotes are valid for 3 months, standard payment terms are net 30, and paying upfront earns a discount. We ship to every country, normally within 15 business days via UPS.
What warranty comes with the Dropometer?
The Dropometer is designed for a 5 year lifetime, and the manufacturer hardware warranty covers all 5 years, along with free software updates. Consumables such as syringes and needles are excluded, and there is a 30-day return window.
Do I need a special phone to use the Dropometer?
No. The Dropometer works with your own iPhone running iOS 15 or later, or you can add a pre-configured Google Pixel for US$295.
Can Dropometer be used outside a lab?
Yes. It weighs under 2.5 kg, runs fully offline, and is airline carry-on compatible, so it works on the production floor, in the field, and in the classroom.
What can a Dropometer measure?
Contact angle (static, advancing, and receding), surface tension (static and dynamic), surface energy, and sliding angle.
