The BT302 is the Orbi-Shaker Jr — the smallest-platform Orbi-Shaker in the BT family, sold at $1,279. 9.5×8" platform is meaningfully smaller than the standard BT3001 (13×12") — designed for bench-space-constrained labs, single-investigator dedicated benches, and small-batch shake-flask workflows where the standard 13×12" platform would be excess capacity. Universal 100–240 V chassis (broader voltage tolerance than the standard BT3001's 115/230 V).

Why the Orbi-Shaker Jr — Compact-Platform Workflows
The Jr platform is positioned between the BT1502 microplate-specific shaker (4 plates, $1,221) and the BT3001 standard flask shaker (13×12", $1,949) — fitting bench-space-constrained labs where 13×12" wouldn't, single-investigator dedicated shake-flask benches at the smallest practical footprint, small-batch workflows of 1–4 flasks per cycle, educational student-cohort shakers, and international installs needing the broader 100–240 V universal input (vs the BT3001's 115/230 V).
Pick the Orbi-Shaker Jr (BT302) when:
- Bench-space-constrained — the smaller platform fits the available bench area
- Single-investigator workflow doesn't need the larger BT3001 platform
- Cost-optimized procurement — $670 cheaper than the BT3001 ($1,279 vs $1,949)
- International procurement — broader 100–240 V voltage tolerance
Step to BT3001 standard ($1,949) when multi-flask workflows exceed the Jr platform capacity.
Step to BT1502 microplate ($1,221) when microplate-format orbital workflows are the primary use.

Application Profile
Bench-space-constrained shake-flask culture — labs with limited bench area.
Single-investigator dedicated shaker — investigator-specific workflow at compact footprint.
Small-batch microbial / cell culture — 1–4 small flasks per cycle.
Educational laboratory teaching — student-cohort dedicated shakers.
Method-development workflows at small-batch scale.
International facility procurement — 100–240 V universal voltage simplifies international installation.
Multi-investigator individual-instrument inventory — multiple Jr shakers vs one shared larger shaker for facility flexibility.
Frequently Asked Questions
Q: What platform size is the Orbi-Shaker Jr? A: 9.5 × 8" — the smallest-platform Orbi-Shaker in the BT family, meaningfully smaller than the standard BT3001 (13 × 12").
Q: How does it compare in price to the BT3001? A: The BT302 is $1,279, $670 cheaper than the standard BT3001 ($1,949).
Q: What voltage does it accept? A: A universal 100–240V, 50–60Hz chassis — broader than the BT3001/BT1011's 115/230V; a 230V configuration is also available by special order.
Q: When should I step up from the Jr? A: Step to the BT3001 standard ($1,949) when multi-flask workflows exceed the Jr platform, or the BT1502 microplate shaker ($1,221) when microplate-format orbital work is primary.
