The Yamato SA-320-115V is a rotary laboratory shaker offering rotary-plus-horizontal and rotary-plus-vertical shaking motions from 20 to 210 rpm at a 40 mm shaking width. The Yamato SA-320-115V is the rotary member of the SA platform — where the SA300 does two-dimensional horizontal/vertical shaking and the SA400 does double-sided vertical shaking, the SA320 adds a rotary component for extraction, culture, and mixing where a swirling motion improves contact. It is a durable 90 W DC-driven benchtop shaker with dial speed and timer control. It is the 115 V unit; the 220 V sibling is the SA320-220V.

Application Profile
Shaking is how a lab keeps a reaction, extraction, or culture homogeneous and gas-exchanged without a stir bar in every vessel. The SA-320-115V's distinctive rotary shaking motion — available combined with either a horizontal or a vertical stroke — sweeps liquid around the vessel rather than merely back and forth, which improves solvent contact in liquid-liquid extractions, suspends settling solids, and aerates shake-flask cultures. Its usable band of 20–210 rpm covers gentle mixing of delicate suspensions through vigorous extraction, and stable performance from low to high speed means results stay reproducible across that range (see mixing-agitation).
The platform is built around interchangeable holders that mount and release easily, so one deck can be reconfigured for centrifugal tubes, test tubes, separating funnels, or Erlenmeyer flasks as the workflow changes (holders are ordered separately). The heavy 40 kg chassis and 90 W DC motor give the SA320 the shaking load to drive full flasks without walking on the bench. A dial timer with a continuous-operation switch handles both fixed-duration and unattended runs. Because the SA300/320 main unit can also be laid on its side for horizontal shaking, one instrument serves multiple agitation geometries (see shaker-selection).
Frequently Asked Questions
What shaking motions does the SA-320-115V provide? Rotary shaking combined with either a horizontal or vertical stroke, at 20–210 rpm with a 40 mm shaking width — a swirling action that suits extraction, culture, and mixing.
How is the SA320 different from the SA300 and SA400? The SA320 adds a rotary motion (20–210 rpm); the SA300 does two-dimensional horizontal/vertical shaking (20–300 rpm); the SA400 does double-sided vertical shaking (20–300 rpm). All share the same holder ecosystem.
Are sample holders included? No — test-tube, separating-funnel, flask, and rack holders are ordered separately so you can match the deck to your vessels.
What is the maximum vessel capacity? Up to five 100 mL, four 200/300/500 mL, three 1000 mL, or two 2000 mL vessels, depending on the holder fitted.
What voltage does it use? The SA-320-115V is the single-phase AC115V (2 A) unit. The 220 V sibling is the SA320-220V.
Ordering & Configuration
quote-based. The SA-320-115V is a benchtop laboratory shaker sold through a quote. At quote we confirm 115 V service and, importantly, the holders you need — test-tube, separating-funnel, Erlenmeyer-flask, or rack holders are ordered separately to fit your vessels. Warranty terms are confirmed with the quote, and lead time is provided at quotation. Request a quote to configure the SA-320-115V with the right holders for your work.
SA laboratory shaker, by motion and voltage: the SA-320-115V (this unit) is the rotary shaker (115 V; 220 V = SA320-220V); the SA-300A adds a rotary-free horizontal/vertical motion, and the SA-400A does double-sided vertical shaking for higher flask counts. Choose the SA320 when a rotary/swirling action improves extraction or culture contact.
