Hi everyone,
I found this device in a lubricants laboratory and I'm trying to identify what it is and what it's used for. Here are the details:
📷 Visual description:
- Cylindrical structure with wood and metal layers.
- Metal handle on top.
- Inside there's a steel capsule containing a dark powder.
- The base features a logo with an “M” and a crown inside a circle.
- There's also the number “85” engraved on the bottom.
🔍 Possible uses (based on preliminary analysis):
- Small-scale metal melting.
- Sample incineration for residue or ash content analysis.
- Thermal testing of lubricants, such as flash point or thermal stability.
❓ Questions for the community:
- Has anyone seen this logo or number before?
- What could the powder inside be?
- Any experience with similar equipment in lubricant or metallurgy labs?
Thanks in advance for any insights!
Hello, after consultation with coleague, I can share with you following info. You can measure the susceptibility of oils to carbon residue formation on this instrument, the so-called CCT (ConradsonCarbon Test). An oil sample is heated with limited air and then the residue is weighed. The CCT was an important test in the development of engine oils, in particular the effect of the quality of the base oil was assessed. Today it's more about additives. Some info you can find also on following link Products - Koehler Instrument Company, Inc. In case of any question, feel free to contact me. Take care Jirka
Wow, thanks for your comments, I guess this is a real piece for the Museum.
Laura Reyes This device appears to be a Conradson Carbon Residue (CCT) apparatus, similar to the K39800 model by Koehler Instrument Company, used to measure the carbon residue of oils according to ASTM D189.
