It features a durable Pyroceram top plate, digital displays for both stirring speed (RPM) and temperature (degrees Celsius), and intuitive control knobs for precise adjustments. This unit is suitable for a wide range of applications in chemistry, biology, and other scientific fields.
Otu ngafe view of the Corning PC-420D Stirring Hot Plate. The unit features a white Pyroceram top plate, a grey base with two black control knobs (Stir and Heat), and two red LED digital displays for RPM and temperature. A power cord with a three-prong plug is visible on the right side.
Ozi nchekwa
Please read and understand all safety precautions before operating the Corning PC-420D Stirring Hot Plate. Failure to follow these instructions may result in injury or damage to the equipment.
- Nchekwa Eletriki: Ensure the unit is connected to a properly grounded 120V/60Hz power source. Do not operate with a damaged power cord or plug. Avoid spills near electrical components.
- Ọkụ Hazard: The Pyroceram top plate can reach temperatures up to 550°C. Always use appropriate personal protective equipment (PPE), such as heat-resistant gloves. Allow the unit to cool completely before handling or cleaning. The "HOT TOP" indicator will illuminate when the surface is hot.
- Nchekwa kemịkalụ: Use caution when heating or stirring flammable or corrosive materials. Ensure adequate ventilation in the work area.
- Nkwanye kwụsiri ike: Always place the hot plate on a stable, level, and heat-resistant surface away from combustible materials.
- Nlekọta: Do not leave the hot plate unattended while in operation, especially when heating liquids.
- Igwe ikuku: Ensure proper ventilation to dissipate heat and any fumes generated during operation.
Melite
- Iwepu: Carefully remove the hot plate from its packaging. Inspect the unit for any signs of damage during transit. Retain packaging for future storage or transport.
- Nkwanye: Position the hot plate on a clean, stable, and level laboratory bench or work surface. Ensure there is sufficient clearance around the unit for ventilation and safe operation.
- Njikọ ike: Connect the three-prong power cord to a grounded 120V/60Hz electrical outlet. The unit is designed for U.S. power standards.
- Rod Mount Support: If using a support rod (sold separately), attach it to the built-in rod mount support on the rear of the unit.
Ntuziaka ọrụ
The Corning PC-420D features intuitive controls for both heating and stirring functions.
Njikwa agafelaview:
- Ihe ngosi ike: An illuminated indicator light confirms the unit is powered on.
- Stir Knob: Located on the left, this knob controls the stirring speed. Turn clockwise to increase RPM. The digital display will show the set RPM.
- Heat Knob: Located on the right, this knob controls the heating temperature. Turn clockwise to increase temperature. The digital display will show the set temperature in degrees Celsius.
- Ngosipụta Dijitalụ: Two red LED displays show the current stirring speed (RPM) and the set temperature (°C). The temperature display will blink until the set temperature is reached.
- HOT TOP Indicator: A warning light indicates when the top plate is hot, even if the heat function is turned off.
Usoro:
- Ike Na: Ensure the unit is plugged in. The power indicator light will illuminate.
- Setting Stirring Speed: Place a stir bar into your vessel and position the vessel on the center of the Pyroceram top plate. Turn the "Stir" knob clockwise to the desired RPM. The digital display will show the set speed. Adjust as needed for proper mixing.
- Ntọala okpomọkụ: Turn the "Heat" knob clockwise to the desired temperature in degrees Celsius. The digital display will show the set temperature and will blink until the set temperature is achieved. The temperature can be set in 5-degree C increments, ranging from 5°C to 550°C.
- Nleba anya: Continuously monitor the process. The microprocessor-based control maintains consistent and repeatable temperature settings within ±2°C.
- Gbanyụọ: When finished, turn both the "Stir" and "Heat" knobs counter-clockwise to the "Off" position. Unplug the unit from the power source when not in use. Allow the hot plate to cool down completely before cleaning or moving. The "HOT TOP" indicator will remain lit until the surface temperature is below 60°C.
- Njikwa Okpomọkụ Mpụga: The unit can be used with an external temperature controller and support rod (sold separately) for enhanced temperature precision. Refer to the external controller's manual for specific instructions.
Nlekọta
Proper maintenance ensures the longevity and optimal performance of your Corning PC-420D Stirring Hot Plate.
- Nhicha:
- Always ensure the unit is unplugged and completely cool before cleaning.
- The Pyroceram top plate is scratch, corrosion, and chemical resistant. Clean spills immediately with a damp ákwà na ncha dị nro. Zere ihe nhicha na-ehicha ihe ma ọ bụ ihe nhicha na-ehicha ihe nke nwere ike imebi elu ahụ.
- The two-piece casting design helps deflect spills away from electrical areas, simplifying cleaning.
- Jiri mgbasa ozi hichapụ mpụta unit ahụamp cloth. Do not immerse the unit in water or spray liquids directly onto it.
- Nyocha: Periodically inspect the power cord for any signs of damage (fraying, cuts). Check the control knobs for smooth operation.
- Nchekwa: Store the hot plate in a clean, dry environment when not in use.
