Question 1

What is the YEK-OVEN 250°C oven and what is it used for?

Accepted Answer

YEK-OVEN 250°C is a natural convection laboratory oven with precise temperature control between 40°C and 250°C. It is preferred for glassware drying, sample pre-drying, moisture removal, and low-temperature thermal processes. Widely used in chemistry, food analysis, soil science, and quality control laboratories. The PID-based temperature control system delivers stable and reproducible results.

Question 2

What are the technical specifications of the YEK-OVEN 250°C oven?

Accepted Answer

YEK-OVEN 250°C operates across 40-250°C with ±1°C accuracy. The natural convection heating system provides silent operation without fan noise. Stainless steel interior ensures easy cleaning and long service life. Volume options are 50 L, 100 L, and 200 L; digital PID controller, timer, and over-temperature protection are standard features.

Question 3

What is the difference between 250°C and 300°C ovens, and which should be selected?

Accepted Answer

The 250°C model is sufficient for routine moisture determination (105°C), glassware drying, food and agricultural sample drying, and plastic curing. The 300°C model is preferred for metallic sample processing and some chemical synthesis applications. If the application temperature generally stays below 200°C, the 250°C model is both economical and adequate.

Question 4

What samples can be dried in the YEK-OVEN 250°C and what are the restrictions?

Accepted Answer

Glassware, ceramics, soil and rock samples, food, grains, and construction materials can be dried without issue. Flammable or volatile solvent-containing samples must NEVER be dried in a closed oven; such processes require a fume hood. For volatile samples, a forced-convection ventilated model should be preferred.

Question 5

How is the YEK-OVEN 250°C calibrated and what are the maintenance requirements?

Accepted Answer

Calibration should be performed every six months using an accredited thermometer at 60°C, 105°C, and 200°C setpoints. Daily maintenance involves wiping the interior with a dry cloth; monthly maintenance includes checking the door seal and ventilation channels. YEKLAB provides calibration certificates and spare parts supply.

Question 6

What are the safety precautions for using an oven?

Accepted Answer

The oven must be placed in a well-ventilated area away from flammable materials. Hot samples must be removed with steel or ceramic containers using heat-resistant gloves. Never place flammable, explosive, or volatile chemicals inside the oven; over-temperature protection must always be active.
