The R4040 is the RotoBot Mini Programmable Rotator — Benchmark Scientific's programmable tube rotator at $823. NEW PRODUCT FAMILY: RotoBot programmable rotators — extends the tube-rotator ladder beyond fixed-speed (R2020) and variable-speed (R2024) with programmable workflow control for repeatable multi-step protocols. Universal-voltage chassis (100–240 V single SKU). Includes holders for 12 × 1.5 mL + 2 × 15 mL + 2 × 50 mL at chassis purchase.
Author confidence note (MEDIUM): No specific RotoBot brochure in available corpus. Confirm exact programmable features (saved-method recall, multi-step protocols, rotation-direction switching), RPM range, and accessory compatibility with Benchmark Scientific tech support. Universe accessory class is incorrect for a capital chassis instrument; flagging FQ-class.
Voltage options: This unit can be ordered with European voltage requirements (230V/50Hz). Contact us to order.

Pick the R4040 RotoBot when:
- Multi-step protocol workflow — programmable recall of complex rotation programs
- Method-development workflows — saved program library across multiple investigators
- Multi-investigator shared facility — per-user saved programs eliminate setup friction
- Production / clinical lab with standardized multi-step rotation protocols
Stay with R2024 Roto-Mini Plus ($823.00) for variable-speed without programming — saves $282.
Stay with R2020 RotoMini ($450) for fixed-speed simple workflows.
Step to H2020 / H2024 Roto-Therm family for temperature-controlled rotation workflows.
Frequently Asked Questions
Q: What makes the RotoBot different from the R2020 and R2024? A: Programmable workflow control for repeatable multi-step protocols, versus the fixed-speed R2020 and variable-speed R2024 RotoMini rotators.
Q: What holders are included with the R4040? A: Holders for 12 × 1.5 mL + 2 × 15 mL + 2 × 50 mL tubes at chassis purchase.
Q: What additional holders are available? A: R4040-150 (15 mL, $22), R4040-1520 (1.5/2.0 mL, $25), R4040-500 (50 mL, $22), and horizontal rotisseries R4040-HZ15 and R4040-HZ50 ($78 each).
Q: What voltage does it use? A: A universal 100–240 V, 50–60 Hz single SKU. The 230 V variant is available by special order.
Ordering & Configuration
Plan additional holder inventory based on intended sample formats — chassis ships with mixed-format holders; expand with R4040-150 / -1520 / -500 / -HZ15 / -HZ50 as needed.
Confirm at quote: voltage / plug type, intended programmable workflow, holder inventory, and lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms.
RotoBot family detail: New family in cohort — programmable variant atop fixed-speed (R2020) and variable-speed (R2024) RotoMini family.
