The Yamato SA-300-115V is a two-dimensional laboratory shaker that mounts vertically for vertical shaking and lays on its side for horizontal shaking, one compact unit covering both motions at 20–300 rpm. Its 40 mm shaking width and powerful DC drive make it a workhorse for extraction, culture, and mixture stirring across separating funnels, flasks, and tubes.

Application Profile
The SA-300 platform earns its place where a lab needs one shaker to do two jobs. Set the shaking table upright for vertical shaking of separating funnels, or lay the main unit on its side for horizontal shaking of Erlenmeyer flasks, test tubes, and centrifuge tubes. The 20–300 rpm range spans gentle culture agitation up to vigorous liquid–liquid extraction, and the thyristor-based Leonard drive delivers stable turns from low to high speed without stepped increments.
Note that glassware and the sample-holder racks are optional accessories: the main unit ships with a fuse, spare carbon brush, and manual. Match the holder to the format you run: separating-funnel holders for extraction, box-type Erlenmeyer clamps for flask culture, or centrifuge/test-tube holders for tube work. In early minutes after power-up the shaking rate may read 10–15% low; a ~15 min warm-up stabilizes it.
Frequently Asked Questions
Can the SA-300-115V shake both horizontally and vertically? Yes. It mounts vertically for vertical shaking and lays on its side for horizontal shaking, the SA300's defining two-way capability, both at 20–300 rpm.
What speed range does it cover? 20 to 300 rpm on both axes, set on a continuous dial with no fixed steps. Maximum rate can run slightly high on 60 Hz mains, so back off the dial if the unit vibrates widely.
Are holders and glassware included? No. The unit includes a fuse, carbon brush, and manual only. Separating-funnel, Erlenmeyer, test-tube, and centrifuge-tube holders are ordered separately.
How many flasks or funnels can it hold? Depending on vessel size: for example five 100 mL, four 500 mL, or three 1000 mL separating funnels. See the holder table for exact counts by capacity.
What voltage does it use? This SKU is the 115V version (single-phase AC115V, 2A). A 220V version is also cataloged. Confirm at order.
Ordering & Configuration
Add to a quote to lock voltage (115V vs 220V), select the sample holders you need, and confirm lead time. Holders and glassware are quoted as separate line items.
Warranty: Per Yamato standard terms. Confirm coverage at quote.
Choosing within the SA family:
- SA-300 (this product): horizontal + vertical shaking, 20–300 rpm
- SA-320: adds rotary (turn) motion, 20–210 rpm
- SA-400: double-sided vertical shaking, higher holder capacity
Pick the SA-300 when you want both linear motions in one compact bench unit and don't need rotary shaking.
