The Yamato SA-400-115V is a double-sided vertical shaker built for throughput. It shakes holders on two sides at once, letting a lab run up to six 1-liter or four 2-liter liquid samples simultaneously. With vertical shaking at 20–300 rpm, a dial-plus-digital speed display, and a larger frame than the SA300/320, it targets extraction and culture work that outgrows a single-sided shaker.

Application Profile
The SA-400 differs from its SA300/320 siblings in one decisive way: it shakes both sides of the unit vertically at the same time. That doubling roughly doubles batch capacity (six 1000 mL or four 2000 mL sample holders in a single run) which suits high-volume extraction, leaching, and culture protocols where each cycle otherwise bottlenecks on how many funnels or flasks fit. The added digital speed display (alongside the dial) makes it easy to reproduce a set rate run-to-run.
As with the rest of the SA family, glassware and the sample-holder racks are not included. Order separating-funnel holders and flask clamps to match your vessels. The SA-400 shakes vertically only (no horizontal mode), so choose it specifically for funnel-and-flask vertical agitation at scale rather than for horizontal flask culture.
Frequently Asked Questions
What makes the SA-400-115V different from the SA-300? It is a double-sided vertical shaker. It agitates holders on two sides simultaneously, so batch capacity is far higher (up to six 1000 mL or four 2000 mL samples). The SA-300 is single-sided and adds a horizontal mode.
How fast does it shake? 20 to 300 rpm vertically, set by dial with a digital readout for repeatable settings.
Does it do horizontal shaking? No. The SA-400 is vertical-only. If you need horizontal flask culture, look at the SA-300 or SA-320.
Are holders and glassware included? No, only a fuse and spare carbon brush ship with the unit. Separating-funnel and Erlenmeyer holders are ordered separately.
What voltage does it use? This is the 115V SKU (single-phase AC115V, 2A). A 220V version (AC220V, 1A) is also cataloged. Confirm at order.
Ordering & Configuration
Add to a quote to confirm voltage (115V vs 220V), choose sample holders sized to your funnels or flasks, and lock lead time.

Choosing within the SA family:
- SA-400 (this product): double-sided vertical, highest capacity, 20–300 rpm
- SA-300: horizontal + vertical, single-sided, 20–300 rpm
- SA-320: rotary (turn) shaking, 20–210 rpm
Choose the SA-400 when parallel throughput matters most and all your work is vertical shaking.
