Frequently Asked Questions
1. What are Hirschmann Ringcaps used for?
Ringcaps are disposable capillary pipettes used for the precise intake and delivery of very small liquid volumes, typically in clinical chemistry, hematology, and medical diagnostics.
2. Why use disposable glass capillaries instead of reusable ones?
Disposable glass capillaries are preferred in clinical settings because they eliminate the need for cleaning and prevent cross-contamination between different patient samples.
3. How do capillary tubes draw up liquid without a pump?
These tubes rely on capillary action, where the surface tension of the liquid and the adhesion between the liquid and the glass walls naturally pull the fluid upward into the tube.
4. Are these tubes compatible with standard pipette controllers?
Many capillary tubes are designed to be used with specialized small-volume pipette holders or controllers that allow the user to dispense the measured volume accurately.
