Obrázok 1: The Titrette 4760161 Digital Bottletop Burette/Dispenser. This image shows the complete unit, including the digital display, control buttons, dispensing tube, and the main body attached to a reagent bottle. The display clearly shows a numerical reading, indicating its digital capabilities.
The Titrette Digital Bottletop Burette consists of several key components:
- Digitálny displej: Shows the dispensed volume with high precision.
- Ovládacie tlačidlá: For power, zeroing, and menu navigation.
- Hand Wheels: For precise manual titration.
- Dispensing Tube: The outlet for the dispensed liquid.
- Recirculation Tube: For priming and air bubble removal.
- Adaptér na fľaše: Connects the burette securely to various reagent bottles.
Nastavenie
- Rozbalenie: Opatrne vyberte všetky komponenty z obalu. Skontrolujte, či nie sú poškodené.
- Bottle Attachment: Select an appropriate reagent bottle. Screw the Titrette burette firmly onto the bottle neck. Ensure a tight seal to prevent leaks. Adapters for different bottle thread sizes are typically included.
- Inštalácia rúrok: Attach the dispensing tube and the recirculation tube to their respective ports on the burette. Ensure the dispensing tube is positioned correctly for your application.
- Príprava: Before first use, or after changing reagents, prime the burette to remove air bubbles. Turn the hand wheels to draw liquid into the cylinder, then dispense it back into the bottle via the recirculation tube until no air bubbles are visible in the cylinder or dispensing tube.
Návod na obsluhu
Basic Dispensing
- Zapnutie: Stlačením tlačidla napájania zapnete digitálny displej.
- Nulovanie: Before starting a new titration or dispensing cycle, press the zero button to reset the display to 0.000 mL.
- Plnenie: Turn the hand wheels to draw the desired volume of liquid into the burette cylinder. Ensure the liquid level is above the zero mark if performing a titration.
- Výdaj: Slowly turn the hand wheels to dispense the liquid. The digital display will show the dispensed volume in real-time. For precise titration, dispense drop by drop as you approach the endpoint.
- Čítanie: Read the final dispensed volume directly from the digital display.
Kalibrácia
Regular calibration ensures the accuracy of your Titrette burette. Refer to the detailed calibration procedure in the full manufacturer's manual for specific steps, which typically involve gravimetric testing with distilled water and adjusting the instrument's settings based on the results.
Údržba
- Čistenie: After each use, especially when changing reagents, rinse the burette thoroughly with an appropriate cleaning solution (e.g., distilled water for aqueous solutions). For stubborn residues, consult the manufacturer's guidelines for compatible cleaning agents.
- Ukladací priestor: When not in use, store the burette clean and dry, preferably attached to a clean, empty bottle or with a protective cap on the bottle adapter.
- Kontrola: Periodically inspect the dispensing tube, recirculation tube, and bottle adapters for any signs of wear, cracks, or damage. Replace damaged components immediately.
Riešenie problémov
| Problém | Možná príčina | Riešenie |
|---|---|---|
| Inaccurate Dispensing | Air bubbles in the system; improper priming; need for calibration. | Re-prime the burette; perform calibration according to the manual. |
| Liquid Leaking | Loose bottle attachment; damaged seals or tubes. | Ensure burette is tightly screwed onto the bottle; check and replace seals/tubes if damaged. |
| Digitálny displej nefunguje | Low battery; electronic malfunction. | Replace batteries; if issue persists, contact technical support. |
