The Yamato AW-47-115V is a semi-automatic benchtop laboratory glassware washer that cleans up to 450 test tubes or 36 volumetric flasks per load using an upward-and-downward two-way pressurized water jet with rotating nozzles. A built-in 1 kW heater brings wash water from room temperature to 60 °C with no boiler or external hot-water plumbing. This is the 115V unit; the 220V sibling is the AW-47-220V.

Application Profile
Consistent glassware cleaning matters because manual washing is variable — residue and detergent carryover confound trace analysis and cell culture. The AW-47 automates the wash with a two-way pressurized jet that drives water both up into inverted tubes and flasks and down over exteriors, while rotating nozzles distribute coverage; the operator simply loads the table, sets a time, and starts.
Because the heater is built in, the washer needs only a cold-water feed at 0.1–0.3 MPa and a drain — no boiler, no hot-water line. The standard flat table suits mixed benchware; the optional jet rack targets narrow-neck or narrow-body glassware whose interiors are hard to reach, and the test-tube rack holds full 450-tube loads. Phosphorus-free detergent is supplied to start, and the SUS interior with chemical-resistant exterior stands up to routine lab reagents.
Frequently Asked Questions
How much glassware does one load hold? Up to 450 test tubes (ø18.5 mm) or 36 100 mL volumetric flasks on the 420 mm spin table.
Does it need a hot-water supply? No. The built-in 1 kW heater raises wash water from room temperature to 60 °C, so only a cold-water feed at 0.1–0.3 MPa and a drain are required.
How does the washing action work? An upward-and-downward two-way pressurized water jet with rotating nozzles cleans both interiors and exteriors; detergent washing is supported.
How do I clean narrow-neck glassware? Add the optional jet rack, which holds up to 36 100 mL flasks and directs jets into hard-to-reach interiors (nozzles are fixed when the jet rack is used).
How long is a wash cycle? Washing time is operator-set from 0 to 60 minutes.
Which voltage is this? This is the 115V unit (AC115V, 13 A); order AW-47-220V for 220V supply.
