Built for closed-circulation heating and cooling, this unit holds a 3.4 L bath and regulates fluid temperature across a −10°C to 80°C range.\u003c\/p\u003e\n\u003cp\u003eA closed circulation cooling system pairs with R-134a refrigerant to pull bath temperature below ambient without an external water feed. Front-mounted, the intake filter removes for fast cleaning, while a standard-equipped drain simplifies fluid changes. Peak flow reaches roughly 6.8 \/ 8.0 L\/min and lift reaches about 3.3 \/ 4.7 m at 50 \/ 60 Hz.\u003c\/p\u003e\n\u003cp\u003ePower runs on AC115V at 50\/60 Hz, matching standard North American bench circuits. Measuring 180 mm wide by 360 mm deep, the circulator fits a crowded benchtop beside the instrument it feeds. Typical pairings include viscometers, spectrofluorometers, and other apparatus needing stable cooling or heating circulation.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide temperature control:\u003c\/strong\u003e regulates the circulating fluid from −10°C to 80°C for both cooling and heating duty.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosed circulation cooling:\u003c\/strong\u003e self-contained loop maintains sub-ambient temperatures without a continuous tap-water supply.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eR-134a refrigeration:\u003c\/strong\u003e sealed refrigerant system (GWP 1430) drives the cooling performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemovable intake filter:\u003c\/strong\u003e front-mounted filter pulls out for quick cleaning and uninterrupted flow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard drain:\u003c\/strong\u003e equipped as standard for straightforward bath emptying and fluid changes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact 3.4 L bath:\u003c\/strong\u003e delivers up to ~6.8 \/ 8.0 L\/min flow and ~3.3 \/ 4.7 m head at 50 \/ 60 Hz from a 180 × 360 mm footprint.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow to Choose the Right Circulator \/ Chiller\u003c\/h2\u003e\n\u003cp\u003eMatching a recirculating circulator to a downstream instrument comes down to a few measurable axes.
