Q1: What are the main differences between ZHPZ and ZQPZ models?
A: The key difference is the refrigeration method. ZHPZ series uses a fluorine‑free compressor and operates from RT+5 to 65°C; ZQPZ series employs a compressor‑based refrigeration system starting from 4°C. The latter is better for low‑temperature cultivation.
Q2: How many layers can be stacked? Are they independently controlled?
A: Supports up to three‑layer stacking, with each layer fully independent (temperature and speed set separately). Power per layer is only 0.7‑1 kW. Total height when stacked is under 1.8 m, saving lab space.
Q3: What is the shaking orbit? Can it be changed?
A: The standard orbit is Φ26 mm circular (suitable for most microbial and cell‑suspension cultures). Other orbit sizes (e.g., Φ50 mm) require special order.
Q4: What is the maximum flask capacity per layer?
A: ZHPZ‑115: up to 53×100 ml or 12×1000 ml flasks. ZQPZ‑190: up to 56×100 ml or 8×3000 ml flasks. Units ship with fixtures for standard capacity.
Q5: What are the temperature uniformity and accuracy?
A: Centrifugal air duct and stepless air‑speed adjustment provide ±0.5 ℃ uniformity at 37 ℃, with 0.1 ℃ resolution. Data measured under no‑load, 20 ℃ ambient, 50% RH conditions.
Q6: What special safety and cleaning features are included?
A: Key features: mirror stainless‑steel seamless chamber (washable), built‑in UV sterilization, auto‑stop shaking when door opens, independent over‑temperature alarm, and removable dust filter on the cooling system.
Q7: What control functions are available?
A: Includes forward/reverse operation, timer (0‑9999 min), fixed‑value/program operation, power‑failure memory. Optional upgrades: LCD touch‑screen programming, micro printer, and 485‑interface remote monitoring.
Q8: What are the operating environment requirements?
A: Ambient temperature must be 5‑25 ℃ for optimal compressor performance. Power supply: AC220 V±10%. Ensure adequate clearance around the unit for ventilation.
Q9: What optional accessories are offered?
A: Options include: micro printer (timed data print), RS485 remote‑control system, and mobile‑APP remote‑monitoring upgrade service.
Q10: Which research fields is this equipment best suited for?
A: Widely used for microbial, viral, bacterial culture, fermentation, hybridization, biochemical reactions, and cell‑tissue research. Plays important roles in medicine, biology, molecular science, pharmaceuticals, food, and environmental protection.
