Q2: What is the price of incubator in Bangladesh (BD)?

Answer: In Bangladesh (BD), the regular market price for the Faithful WP-25A Constant-Temperature Incubator typically ranges between BDT 32,000 and BDT 42,000, depending on import duties, shipping, and supplier warranty terms. For official corporate price quotes, institutional tenders, and direct stock availability in BD, contact authorized laboratory distributors such as Federal Scientific Mart (fsm.com.bd).

Q3: What warranty coverage and local technical support are provided in Bangladesh?

Answer: The Faithful WP-25A comes standard with a 12-month (1-year) factory warranty covering heating element failures, PID controller defects, and electrical faults. Authorized local suppliers like Federal Scientific Mart provide local technical support, replacement shelves, temperature sensor probes, and spare heating components across Bangladesh.

Q4: How does the WP-25A differ from the WHL-25A drying oven model?

Answer: While both models share identical 18-liter desktop cabinet dimensions (260 x 260 x 260 mm) and exterior footprints:

• WP-25A (Incubator): Designed for biological incubation with a temperature range of Room Temperature +5 degrees C to 65 degrees C and a lower power rating of 0.18 kW.

• WHL-25A (Drying Oven): Designed for high-temperature sample drying and sterilization with a range of Room Temperature +10 degrees C to 300 degrees C and a 0.6 kW heating element.

Q5: Which primary applications and laboratory workflows utilize the WP-25A?

Answer: The WP-25A incubator is engineered for routine microbiological and biological applications, including:

• Culturing bacteria, fungi, and microorganisms at stable physiological temperatures.

• Water analysis, BOD testing, and agricultural seed germination tests.

• Enzyme assays, sample incubation, and molecular biology research protocols in medical and university laboratories.

Q6: How do you operate and set up the WP-25A incubator step-by-step?

Answer:

1. Place the incubator on a stable, level, heat-resistant workbench with adequate clearance around the top 35 mm exhaust port.

2. Plug the power cord into a properly grounded AC 220V power socket.

3. Load samples onto the wire mesh shelves, leaving sufficient space between containers for natural air convection.

4. Use the touch-button control panel to program your target incubation temperature and run duration (0 to 9999 minutes).

5. Switch on the power; the PID controller engages the heating elements, and the dual LED screen displays real-time and set temperatures.

6. Once incubation is complete, the unit auto-stops or sounds its alarm, allowing safe sample retrieval.

Q7: What safety and advanced control features are integrated into the unit?

Answer:

• Over-Temperature Alarm: Built-in sound and light alarm triggers immediately if internal temperature exceeds safe operating thresholds.

• Advanced PID Functions: Includes sensor deviation correction, temperature overshoot self-tuning, internal parameter locking, and power-off parameter memory.

• Anti-Scald Handle: Designed with a modern anti-hot handle to protect operators during frequent door openings.

Q8: How do you properly clean and maintain the incubator?

Answer:

• Chamber Sanitation: Always disconnect power and let the incubator cool before cleaning. Wipe down the inner chamber walls with a soft cloth and mild disinfectant or 70% isopropyl alcohol.

• Exterior Care: Clean the cold-rolled steel outer shell with a damp cloth; avoid abrasive scouring pads.

• Door Seal Inspection: Periodically check the door silicone gasket for cleanliness and tight closure to prevent thermal leakage.

Q9: What items are included in the standard factory package when purchased?

Answer: The complete factory package includes:

• Faithful WP-25A Constant-Temperature Incubator main unit

• 2 x Stainless steel wire mesh shelves with brackets

• Power cable with ground connection

• User instruction manual and factory quality inspection certificate
