The Yamato SA-300B is the SA300 2-way laboratory shaker supplied with the adjustable Erlenmeyer flask holder (Part No. 232097) — a ready-to-run flask-shaking package. The SA300 delivers horizontal and vertical reciprocating motion at 20–300 cycles/min, and the bundled holder secures 100–1000 mL Erlenmeyer flasks on the deck for culture, mixing and dissolution work.

Application Profile
The SA300's 2-way reciprocating motion — straight-line horizontal or vertical shaking — is the classic choice for suspension culture, mixing and dissolution in flasks, where a back-and-forth stroke keeps liquid moving and aerated. Bundling the adjustable Erlenmeyer flask holder (232097) makes the SA-300B usable out of the box for the most common lab vessel: the holder adjusts to grip 100 mL through 1000 mL flasks securely at up to 300 cycles/min. The 40 mm stroke and stepless speed let an operator dial the agitation energy a protocol needs, and the 0–60 min timer supports unattended runs. Additional holders (centrifugation tube, test tube, separating funnel) share the same deck if the vessel mix changes.
For orbital/rotary swirl instead of straight reciprocation, the SA320 (e.g. SA-320-220V) provides turn shaking on the same chassis.
Frequently Asked Questions
What's included in the SA-300B? The SA300 2-way shaker plus the adjustable Erlenmeyer flask holder (232097), which grips 100–1000 mL flasks.
What shaking motion and speed does it provide? Horizontal/vertical reciprocating motion at approximately 20–300 cycles/min, with a 40 mm stroke.
Can I run other vessels? Yes — centrifugation-tube, test-tube and separating-funnel holders are available for the same deck.
How is it different from the SA320? The SA300 does 2-way reciprocating shaking (up to 300/min); the SA320 does rotary/turn shaking (up to 210/min).
What voltage is it? The SA300 spec sheet lists 100V AC; confirm your 115V build and supply at quote.
Ordering & Configuration
Confirm at quote: supply voltage, whether the bundled Erlenmeyer holder (232097) covers your flask sizes or you need additional holders, and bench space for the 460 × 460 × 425 mm, ~40 kg unit.
Warranty: Per Yamato standard terms — confirm coverage at quote.
Add the Yamato SA-300B to a quote to lock voltage and holders.
Positioning: the SA-300B is the flask-ready 2-way shaker bundle (SA300 + Erlenmeyer holder) — choose it for reciprocating flask work up to 300 cycles/min; step to the SA-320 for rotary/turn shaking or extraction in separating funnels.
