The Wincom HH-4 Thermostatic Water Bath is a portable laboratory instrument designed to maintain stable, constant temperatures for samples using indirect heat transfer. It is widely used in school, hospital, industrial, and scientific research laboratories for distillation, concentration, chemical reagent dipping, and cultivating biological cultures.
Key Product Features
- Stainless Steel Chamber: The inner water tank is manufactured using high-quality stainless steel, offering high thermal resilience and anti-cauterization/anti-corrosion protection.
- Digital Control Panel: Features an operational amplifier temperature controller and an automatic digital display to accurately monitor and adjust the water medium’s heat level.
- Adjustable Openings: The 4 holes are equipped with modular concentric rings to accommodate various sizes of flasks, beakers, and test tubes.
Basic Operating Procedure
- Fill Tank: Pour distilled water into the stainless steel reservoir. Ensure it covers the heating element but does not overflow when vessels are placed inside.
- Power On: Plug the unit into a 220V outlet and flip the power switch.
- Set Temperature: Use the digital controller to enter the target processing temperature.
- Equilibrate & Load: Wait for the digital display to signal that the water medium has reached equilibrium before gently immersing your sample containers.
- Shutdown: Power off the device, remove the samples, and safely drain the chamber after the water cools to prevent mineral scale deposits.
