Reduce The Internal Surface Roughness Of A Probe With DP3®

Posted on January 26, 2017

Newly marketed diagnostic instruments and their assays are becoming more and more sensitive. This greater sensitivity is likely to require more stringent control of carryover from one sample being tested to the next. Thus, a probe’s internal diameter (ID) surface finish now plays a greater role in the ability of the instrument to accurately analyze and diagnose the presence of infections and disease.

It’s these small, hard-to-reach rough areas within a probe’s ID that invite carryover and increasingly become problematic for OEM design teams as previous probe manufacturing technologies are just not up to snuff.

So, where does one turn for an alternative?

Coatings are one approach tried by many instrument designers. But how can you tell if a coating starts to flake off inside the probe?

Enter DP3®
DP3 is Diba’s precision technology that polishes and smooths a probe’s internal surface and reduces surface roughness by up to 75%. This proprietary process improves wash characteristics and creates an extremely durable surface that can enhance the performance of an existing probe design, and unlike coatings, will not flake off over time.

When coupled with Diba’s proprietary probe draw down process to reduce tip ID while maintaining a smooth inner surface, DP3 enables precise dispense and aspirate functions for the most demanding new diagnostic assays.

Diba’s application engineers work closely with our customers’ OEM engineering teams to customize probe design according to the application needs of each instrument. Our customers have verified that this attention to detail can become the deciding difference for sensitive assays, where any minute amount of carryover can become a serious problem.
