Centrifugal Tube with stand

Our Centrifuge Tubes are designed for precise determination of solid particle content in inspection mediums used for Magnetic Particle Examination. Maintaining the correct particle concentration in the suspension is a critical factor in the inspection process, ensuring reliable and accurate results. As part of quality control, concentration levels are checked after preparation and monitored regularly—typically every eight hours or at each shift change.

Salient Features:

Easy and accurate measurement
Helps monitor contamination levels in the bath
Individually calibrated tubes for precision
Available in different least counts for visible and fluorescent suspensions
Options available with 0.05 ml & 0.1 ml least count

How to Check the Concentration:

1️ Agitate the particle suspension for at least 30 minutes to ensure uniform distribution.
2️ Take a 100-mL sample of the agitated suspension and place it in a centrifuge tube with a graduated stem:

• 0.05 ml increments for fluorescent baths

• 0.1 ml increments for non-fluorescent baths

3️ Demagnetize the sample and allow it to settle undisturbed:

• 60 minutes for petroleum distillate suspensions

• 30 minutes for conditioned water suspensions

4️ Read the settled particle volume:

• Fluorescent magnetic particles: 0.1 to 0.4 ml per 100 ml

• Non-fluorescent magnetic particles: 1.2 to 2.4 ml per 100 ml

• Dual-coloured particles: Settling volume should align with performance and lighting requirements as per manufacturer recommendations.
