How to reduce contamination from the surface of sample vessels

Over the past two decades, materials identified as being non-contaminating (PTFE, quartz) have become the top choices for reaction vessels... for ultra trace analysis

Microsampling Inserts

TFM or Quartz inserts are useful for microsampling applications. They allows to increase the throughput of a 12 position rotor up to 36 positions.
300°C and 100 bar can be reached within sealed vessel.
Microsampling inserts fit within 100 ml vessels and use standard temeprature monitoring.

High Purity Quartz Inserts

They are the ideal solution for ultra-trace analysis because their convex surface prevents loss of analytes from condensation.

• 50 ml high purity quartz inserts
• Convex surface prevents loss of analytes from condensation
• Minimize electrostatic effects
• Fits within standard 100 ml vessels, uses standart temperature monitoring

Extra High Purity TFM Inserts

They minimize the acid volume and optimize the dilution factor.

• 30 ml, extra high purity TFM
• Ideal for smaller samples
• Minimize acid volume
• Optimize dilution factor
• fits within standard 100 ml vessels, uses standard temeprature monitoring
