Real-World Testing: Putting Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020-1110, Case of 12 to the Test
First Use Experience
I initially tested the Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020-1110, Case of 12 in our small-scale analytical chemistry lab, focusing on solution preparation for environmental testing. I needed precise measurements of various reagents in both aqueous and solvent-based solutions.
The pipets performed admirably under varied conditions, maintaining their accuracy even with moderately viscous liquids. The clear markings and controlled flow allowed for extremely precise dispensing, crucial for replicating experiments consistently.
These pipets were straightforward to use, even for technicians with varying levels of experience. The red band color-coding for the 1 mL size was immensely helpful in quickly identifying the correct pipet, streamlining our workflow.
The only initial issue I encountered was the small tip opening, which was deliberate in the design of the Mohr pipets, which lead to slower dispensing of viscous solutions, but this was easily mitigated by adjusting dispensing speed.
Extended Use & Reliability
After several months of continuous use, the Kimble/Kontes KIMAX Brand Reusable Measuring (Mohr) Pipets, Class B, Color-Coded 37020-1110, Case of 12 have proven remarkably resilient. There were no chips or cracks from regular handling, indicating good glass quality.
