Immersion Circulation Bath
|
Superior Thermal Uniformity: |
External Pump Capacity: |
Versatile Applications: |
Instrument Temperature Control: |
|
Unlike conventional static baths, the active internal circulation mechanism maintains a precise thermal uniformity of ±0.1°C. |
Delivers a reliable flow rate of 8 liters/min at 0.3 bar pressure to support external closed-loop systems. |
Perfect for sample preparation (warming reagents/media, thawing, tempering) and biological processes (incubation, cell culture, enzyme assays). |
Easily regulates external laboratory equipment, including chromatography columns, viscometers, and densitometers. |

Features
Controller
· JSC-0D Digital PID Controller: Provides high-precision ±0.1°C control with an easy-to-read LED display.
· Automatic Start/Stop Timer: Offers adjustable scales (99 min 59 sec / 99 hr 59 min / 99 days 23 hr) or continuous operation.
· Advanced Tuning: Features built-in temperature calibration and an auto-tuning function.
· Sensor Type: Premium Pt-100Ω sensor for accurate thermal monitoring.
-----
Construction
· Durable, epoxy powder-coated metallic exterior casing.
· Easy-to-clean, electro-polished seamless Stainless Steel 304 bath.
· Heavy-duty Stainless Steel 304 components including the immersion heater, lid, and perforated protective cover.
-----
Performance
· Temperature Range: Ambient +5°C to 100°C.
· Accuracy & Uniformity: Exceptional control accuracy within ±0.1°C and thermal uniformity within ±0.2°C.
· Rapid Heating: Corrosion-resistant Stainless Steel 304 sheath immersion heater directly heats water in the bath to reach the set temperature quickly.
· Dual-Purpose Circulation Pump: The stainless steel immersion pump circulates thermal fluid internally for high thermal uniformity, or externally to a closed-loop system at an 8 L/min flow rate and 0.3 bar pressure.
-----
Convenience
· Integrated drain port for effortless emptying of the bath fluid.
· Supplied with a flat stainless steel cover to drastically reduce heat loss and fluid evaporation.
· Equipped with Φ9 mm hose barb inlet and outlet fittings for easy external circulation connectivity.
-----
Safety Systems
· Triple-Layer Over-Temperature Protection:
o Digital Cut-Off: Shuts down the heater and triggers an audio-visual alarm if the temperature rises +2°C above the setpoint.
o Analog Backup: Independent safety cut-off engages if the temperature exceeds 10% above the setpoint.
o Max Temperature Limit: Hard cut-off with an audio-visual alarm if the unit exceeds its absolute maximum temperature limit by +1°C.
· Sensor Disconnection Alarm: Alerts the user immediately if sensor continuity is lost.
· Low Water Level Cut-Off: Prevents dry boiling and protects the immersion elements.
· Electrical Safety: Integrated over-current fuse protection.
