Naudojimo instrukcijos
This Erlenmeyer flask is designed for general laboratory use, including mixing, heating, cooling, incubation, filtration, and titration.
Naudojimo gairės:
- Užpildymas: Carefully pour liquids into the flask. The wide mouth facilitates easy pouring and minimizes spills.
- Matavimas: Use the white enamel graduations for approximate volume measurements. For precise measurements, use calibrated volumetric glassware. The graduations range from 50 mL to 200 mL.
- Maišymas: Swirl the flask gently to mix contents. The conical shape aids in efficient mixing without splashing.
- Šildymas: The flask is designed with uniform wall thickness for thermal shock resistance. It can be heated on a hot plate, with a Bunsen burner (using a wire gauze), or in a water bath. Ensure even heating to prevent localized stress.
- Aušinimas: The flask can be cooled in an ice bath or refrigerator.
- Sandarinimas: If sealing is required, use a No. 8 rubber stopper (not included) to ensure a secure fit.

Trikčių šalinimas
While the Corning Pyrex flask is a robust piece of equipment, issues can arise from improper handling or use.
| Problema | Galima priežastis | Sprendimas |
|---|---|---|
| Flask breaks during heating/cooling | Sudden or extreme temperature changes; pre-existing micro-cracks. | Ensure gradual heating/cooling. Inspect flask for damage before use. Discard damaged glassware. |
| Chipping around the rim | Impact with hard surfaces; improper handling. | Handle with care. The heavy-duty rim is designed to reduce chipping, but not eliminate it entirely. Discard if chipped. |
| Residue difficult to remove | Dried-on chemicals; inappropriate cleaning method. | Clean immediately after use. Use appropriate detergents or specialized cleaning solutions for specific residues. Consider soaking. |
