Laboratory and Research Melting and Heated Holding Tanks for R&D, Pilot and Universities
Short answer: Labs, universities and pilot plants need compact stainless tanks with digital material-temperature control that melt or hold small batches repeatably and scale to production without changing the process. WaxMelters' PRIMO 25 (25 lb / 3.5 gal, 300 W, $1,395) is positioned for lab, R&D, samples and very small batches; the PRIMO 3 Thermal Conditioning (3.5 gal, $1,645) gives gentler extended holding at the same size; the PRIMO SP-3 (3.5 gal, $1,395) suits soap and oil formulation work; and the PRIMO 14 heated holding tank ($1,995) keeps already-liquid material warm for dispensing. The same PRIMO families scale to 60,000 lb, so pilot results carry over to production.
How to choose a lab or pilot tank
- Melt or hold? Standard PRIMO melts solids; PRIMO Thermal Conditioning holds temperature-sensitive materials with gentler, extended control; heated holding tanks keep already-liquid material warm.
- Plan the scale-up path. Choose the family you would use in production; WaxMelters lists TC 3–35 for lab, R&D and pilot work and Rapid-Cycle 25–100 for lab, R&D and small repeated-load production.
- Match the temperature. Standard PRIMO and Thermal Conditioning tanks run 0–212 °F; an X-Treme high-temperature configuration runs up to 400 °F (204 °C), for example +$250 on the PRIMO 25 and +$1,250 on the PRIMO 1000. Heated fillers run 0–212 °F as standard, with an optional X-Treme range of 0–300 °F.
- Check purchasing needs. WaxMelters works with universities, laboratories, government agencies and institutions that need vendor forms, formal quotations or confidentiality documentation.

What is the best small melting tank for a research lab?
The PRIMO 25 (25 lb / 3.5 gal, 300 W, $1,395) is positioned for lab, R&D, samples and very small batches, with digital material-temperature control. For gentler extended holding, choose the PRIMO 3 Thermal Conditioning (3.5 gal, $1,645).
Do lab results carry over to production?
The same PRIMO families run from 3.5 gal and 25 lb up to 60,000 lb, so a process proven on a small PRIMO can move to a production PRIMO of the same family.
Can WaxMelters handle university and government purchasing?
Yes. WaxMelters works with universities, laboratories, government agencies and institutions that need vendor forms, formal quotations, financing documentation or confidentiality agreements.
Which tank holds an already-liquid sample warm?
The PRIMO 14 heated holding and dispensing tank (14 gal, 800 W, $1,995) is for material that is already liquid and only needs to stay warm for dispensing.
Can lab tanks run hotter materials?
Yes. An X-Treme configuration runs up to 400 °F (204 °C); it is +$250 on the PRIMO 25.
