The analog controller features accurate, proportional temperature control and includes a thermometer for temperature readout.

The 6L (1.6gal.) baths provide precise, stable temperature control down to –20°C (–4°F). The 21cm (81/4") wide footprint helps conserve precious bench space. Baths have a cooling capacity of 200W at 20°C (68°F), 140W at 0°C (32°F), and 100W at –10°C (14°F).

Energy-efficient 13L (3.4gal.) baths combine high heat removal with a large reservoir and work with temperatures as low as –40°C (–40°F). Model 1150S has a cooling capacity of 660W at 20°C (68°F), 480W at 0°C (32°F), and 100W at –30°C (–22°F). Model 1190S has a cooling capacity of 680W at 20°C (68°F), 450W at 0°C (32°F), and 160W at –30°C (–22°F).

The 28L (7.4gal.) baths are for immersing large numbers of samples. The large capacity of this reservoir helps compensate for unexpected heat load changes. The large bath opening allows convenient access and has a large workspace on top. Baths have a cooling capacity of 700W at 20°C (68°F), 510W at 0°C (32°F), and 260W at –20°C (–4°F).

The 120V models are CSA certified. The 240V models are CE approved.

The general-purpose clear bath algicide is compatible with stainless steel and helps keep water baths clean, odor-free, and resistant to black algae. One 237mL (8oz.) bottle treats approximately 757L (200gal.). Supplied in a plastic dispenser bottle. Use the concentrated bath cleaner for cleaning and removing rust and minerals deposits from stainless steel and plastic baths. Bath cleaner comes in 473mL (16oz.) bottle; 29.6mL (1oz.) treats approximately 7.6L (2gal.).

The high-temperature tubing is 0.9m (3') of flexible fluoropolymer resin-lined, stainless steel overbraid tubing with 6.4mm (1/4") NPT quick connects on both ends. For use at elevated temperatures. Maximum temperature: 300°C (572°F).

The Dynalene® HC 50 heat transfer fluid provides superior thermal stability for high or low temperatures. Fluid has a temperature range of –53 to 60°C (–63 to 140°F), a –56°C (–68.8°F) freezing point, and a viscosity (in centistokes) of 3.6 at 0°C (32°F) and 15.1 at –40°C (–40°F).

Note: Heat transfer fluid is incompatible with Buna or natural rubber.

Ordering Information: Includes lid; 0.6m (2') bypass tube; male inlet/outlet tubing adapters for 0.95cm (3/8"), 0.64cm (1/4"), and 0.48cm (3/16") tubing; and 1.8m (6') cord with standard U.S. plug on 120V models, European plug on 240V models.
