"Vacuum pump SHB-III"

Dependable Vacuum Solutions: The SHB-III Water Circulating Pump

Running vacuum filtrations and rotary evaporations day after day, you need a pump that won't quit on you. The SHB-III delivers 0.098 MPa vacuum depth with an 80 L/min flow rate, handling everything from Buchner funnel filtrations to solvent recovery without the mess and maintenance headaches of oil-based systems.

Water circulation keeps things clean and simple—just fill the 15-liter reservoir, plug it in, and you're pulling vacuum in seconds. No oil changes, no oil mist filters, no oil contamination in your samples. It's the kind of equipment that just works when you need it to work.

Engineered for High-Frequency Filtration and Evaporation Tasks

Flow rate of 80 L/min handles multiple vacuum lines simultaneously, so you can run a rotovap and a filtration setup at the same time without losing suction. The 180W motor pulls consistent vacuum while staying quiet enough that you can actually hear your lab partner when they're asking questions.

Here's what makes it practical for daily use:

• Dual voltage compatibility (110V/220-240V) means it works anywhere your lab is located
• Anti-corrosion materials stand up to solvent vapors and acidic fumes that would eat through cheaper pumps
• Compact 385 x 280 x 420 mm footprint fits under fume hoods where space is tight
• Just 11 kg, so you can move it between benches without throwing out your back

Quiet Operation for Extended Laboratory Workflows

You'll appreciate how quiet it runs during those long evaporation sessions. When you're working with a TOPT-1L Glass Jacketed Reactor (Double glass reactor) or scaling up to a TOPT-3L jacketed glass reactor (double glass reactor), the last thing you need is a noisy pump drowning out everything else in the lab.

Pair it with a Cooling circulator Chiller LX-0400 for extended runs, and you'll prevent the water from heating up and losing vacuum efficiency. Labs running Glass Jacketed Reactor (Double Glass Reactor) TOPT-5L setups benefit from this combination during reflux and distillation operations where consistent vacuum matters for hours at a time.

Efficient Water-Based Vacuum Technology

Oil-free operation means you're not constantly checking oil levels or dealing with contaminated oil disposal. Just keep an eye on the water level in that 15-liter tank and change it out when it gets cloudy.

Rotary evaporation: Pulls enough vacuum for efficient solvent removal at lower bath temperatures, protecting heat-sensitive compounds. Works seamlessly with standard rotovaps for methanol, ethanol, and acetone recovery.

Vacuum filtration: Speeds up filtrations that would otherwise take forever with gravity alone. Great for filtering precipitates, collecting crystals, or clarifying solutions.

Reactor applications: Connect to glass jacketed reactor systems for small-scale synthesis under reduced pressure. Provides stable vacuum for degassing reactions and low-pressure distillations.

Labs needing higher capacity should consider the Vacuum pump SHB-B95 for larger reactor volumes, but for benchtop work and teaching labs, the SHB-III hits the sweet spot between performance and portability. Keep the water reservoir filled, drain it before storage, and this pump will run for years.
