8. FAQ
Q1: What’s the difference between natural convection and forced-air ovens?
A1: Natural convection ovens circulate air gently for low-disturbance drying, while forced-air ovens use fans to deliver faster and more uniform heat distribution.
Q2: Can a lab drying oven be used for sterilisation?
A2: Yes, hot air sterilising ovens achieve 160–180°C for effective dry-heat sterilisation of glassware and tools.
Q3: What makes a PID drying oven better than a conventional model?
A3: PID control ensures stable, precise temperature regulation with minimal deviation, ideal for sensitive materials and reproducible experiments.
Q4: Which model is best for heat-sensitive materials?
A4: The vacuum drying oven or automatic precision vacuum model is ideal for drying materials that degrade, oxidise, or decompose easily.
Q5: How can I maintain consistent temperature uniformity?
A5: Regular calibration and balanced loading of shelves help maintain ±2.5–3.5% uniformity. Forced-air systems also enhance temperature stability.
