Welcome to CEM.com


Overview

Our unique quartz fiber crucibles significantly reduce the time required to ash samples compared to other non-porous crucibles such as ceramic or platinum. With improved airflow throughout the crucible, samples can be ashed up to 90% faster and are compatible with any type of muffle furnace. CEM’s quartz fiber crucibles cool to the touch in seconds, making them safer to use and allowing users to skip the desiccation process.

Features

  • Use in any muffle furnace
  • 90% time savings compared to ceramic or platinum crucibles
  • Crucibles cool to the touch in seconds for safer handling
  • Instant cooling means there is no need for desiccation between the ashing process and re-weigh
CEM - Faster

Faster

The quartz fiber crucible design allows air to circulate within the sample, cutting test times to as low as 15 minutes.
CEM - Safer

Safer

Crucibles cool to the touch within seconds, reducing the risk of burns significantly compared to ceramic crucibles.
CEM - Easier

Easier

The crucibles cool almost instantly. They can be weighed immediately after ashing without long cooling times or the need for desiccation.

Crucibles, caps and liners offer the ultimate flexibility.

1. Cap

For low density samples, crucible caps will help to contain the sample and prevent ash from being lost during handling.

2. Crucible Liner

For wet or viscous samples, crucible liners ensure sample does not soak through the crucible.

3. Quartz Fiber Crucible

The fastest, safest, easiest to use crucible in the industry. Choose between 20 mL, 50 mL and 100 mL capacities depending on the size of sample you wish to analyze.
