Product Description
A laboratory shaker earns its place when agitation has to be repeatable. Swirling a flask by hand mixes it, but no two operators swirl the same way and nobody swirls for four hours. The Yamato SA-320-220V runs horizontal 20–210 rpm; vertical 20–210 rpm with a 90 W DC motor and a 0–60 minute timer with continuous switching, so an extraction, a dissolution test or a culture gets the same treatment every time, logged as a speed and a duration rather than as an operator's technique.
The SA-320 adds rotary motion on top of the horizontal and vertical strokes. That compound path keeps the liquid climbing the flask wall instead of sloshing back and forth along one axis, which is what you want for gas exchange in a culture, for suspending a settling solid, or for extractions where the interfacial area does the work. The trade-off is speed: the compound motion tops out at 210 rpm rather than 300. All three SA models share the same platform: a DC motor sized well above the load so speed does not sag as flasks fill, dial-set speed control, and a chassis heavy enough (about 40 kg) that it stays put on the bench instead of walking across it at high frequency.
Key Features
- Rotary + horizontal / rotary + vertical shaking
- Horizontal 20–210 rpm; vertical 20–210 rpm
- Sample capacity: 100 mL × 5, 300 mL × 4, 1000 mL × 3, 200 mL × 4, 500 mL × 4, 2000 mL × 2
- 90 W DC motor — speed holds under load rather than dropping as the platform fills
- Timer 0–60 min in 5-minute graduations, plus a continuous-run switch for overnight work
- Dial setting for speed
- Heavy chassis (~40 kg) — resists walking at high shaking frequency
- Flask holders and clamps selected to match your vessel sizes

What's Included
- SA-320-220V laboratory shaker
- Spare fuse (1)
- Spare carbon brush (1)
- Instruction manual
Flask holders, clamps, springs and platform accessories are ordered separately and chosen to match your flask sizes — tell us what vessels you run and we will specify them.
Installation Requirements
- Electrical: single phase AC 220 V, 1 A, 50/60 Hz.
- Bench: a level, rigid surface rated for approximately 88 lb. A shaker on a flexible bench transmits vibration to everything else on it.
- Clearance: allow room around the platform for the shaking stroke and for loading flasks.
Compliance
Country of origin: Japan. One-year manufacturer warranty.
