Frequently Asked Questions
1. Can HWS Labortechnik build a reactor based on my specific sketch?
Yes. HWS specializes in custom glass blowing and technical glass construction. They can take individual researcher sketches and turn them into fully functional, pressure-tested laboratory equipment.
2. What temperature range can HWS jacketed reactors handle?
HWS jacketed vessels are typically designed to operate from -60°C up to +200°C, depending on the thermal fluid used and the specific seal materials selected for the system.
3. Are HWS reactors compatible with standard overhead stirrers?
Yes, HWS reactors utilize standard NS ground joints or flat flanges, making them compatible with common overhead stirrers from brands like IKA or Heidolph when used with the appropriate HWS stirrer bearings.
4. How do I safely clean complex HWS glass assemblies?
Due to their high-grade borosilicate construction, HWS glass can be cleaned with most laboratory solvents or in a laboratory dishwasher. For complex reactors, it is recommended to disassemble the seals and valves to ensure no residue remains in the dead spaces.
