The BIS-2 Benchtop Shaking Incubator delivers precise, simultaneous temperature-controlled incubation and orbital shaking in a compact, laboratory-bench-friendly footprint. Designed for microbiology, cell culture, fermentation studies, and biochemical research applications, the BIS-2 combines a touch screen LCD control interface, 40–250 rpm orbital shaking range, and a temperature range from RT+5°C to 65°C — providing the stable, uniform mixing environment required for reproducible biological and biochemical laboratory results. With a 350 × 350 mm platform supporting up to 26.5 kg and flask configurations from 50 mL to 1000 mL, the BIS-2 is the compact shaking incubator of choice for laboratories requiring reliable orbital mixing without sacrificing bench space.

AvailableThe BIS-2 Benchtop Shaking Incubator integrates touch screen control, precise orbital shaking from 40–250 rpm, a 20mm amplitude platform, and RT+5°C to 65°C temperature control — delivering the uniform mixing and stable incubation conditions required for microbial culture, cell culture, and biochemical research in a compact benchtop format.
The BIS-2 is operated via an intuitive touch screen control system with a large LCD interface, providing clear, real-time display of actual and target temperature, actual and target shaking speed, and timer status — all from a single operator panel. The touch screen interface eliminates the need for rotary knobs and push buttons that accumulate contamination in laboratory environments, provides precise digital setpoint entry with 0.1°C temperature resolution and ±1 rpm speed accuracy, and reduces operator error associated with analogue control systems during setpoint adjustment.
The BIS-2 maintains temperature from RT+5°C to 65°C with a control accuracy of 0.1°C — providing the stability required for mammalian cell culture at 37°C, microbial culture at 37°C and 42°C, and biochemical reaction incubation at a range of physiological and non-physiological temperatures. Orbital shaking speed is independently controlled from 40 to 250 rpm with ±1 rpm accuracy — covering the low-speed gentle mixing required for sensitive mammalian cell culture applications through the high-speed agitation required for aerobic microbial culture and fermentation studies.
The BIS-2's exterior dimensions of 490 × 690 × 450 mm make it one of the most space-efficient orbital shaking incubators available for its platform size and load capacity. The compact footprint allows the BIS-2 to be positioned on a standard laboratory bench alongside other equipment — an important practical consideration in laboratories where bench space is at a premium and floor-standing equipment is not feasible. Despite its compact design, the BIS-2 accommodates up to 36 × 50 mL flasks, 13 × 250 mL flasks, or 4 × 1000 mL flasks on its 350 × 350 mm platform.
The BIS-2 is fitted with a transparent lid that provides continuous visual access to samples during shaking and incubation — without requiring the lid to be opened, which would disrupt the temperature environment and contaminate cultures. The transparent lid allows operators to observe culture turbidity, colour changes, foam formation, and sample status at a glance during incubation — a practical feature for monitoring fermentation progress, identifying culture contamination events early, and verifying that all flasks are shaking correctly without interrupting the running protocol.
The BIS-2's orbital shaking mechanism delivers a consistent 20 mm amplitude orbital motion across the 350 × 350 mm platform at all speeds within the 40–250 rpm range. The stable shaking mechanism minimises vibration transfer to the bench surface and ensures that all flasks on the platform — regardless of their position relative to the centre — experience the same orbital motion amplitude and frequency. Uniform mixing is essential for reproducible culture results, as spatial variation in shaking intensity creates inconsistent oxygen transfer rates between flasks, leading to variability in cell density, product yield, and metabolite accumulation.
The BIS-2 provides full independent adjustability of shaking speed (40–250 rpm), temperature (RT+5°C to 65°C), and a programmable timer from 1 minute to 99 hours 59 minutes. The extended timer range allows the BIS-2 to be programmed for short biochemical reaction incubations through multi-day fermentation studies and overnight microbial culture protocols — without requiring operator presence for cycle termination. The combination of precise setpoint control across all three parameters makes the BIS-2 suitable for a broad range of temperature and agitation-sensitive laboratory applications.
The BIS-2 accommodates flasks from 50 mL to 1000 mL using appropriate spring clamp or universal flask holder accessories — supporting the full range of standard microbiology, cell culture, and biochemical research flask formats. The 350 × 350 mm platform and 265 mm interior height provide sufficient space for tall-neck Erlenmeyer flasks at all supported sizes. Compatible flask configurations: 50 mL × 36, 100 mL × 23, 250 mL × 13, 500 mL × 8, 1000 mL × 4.
The BIS-2 Benchtop Shaking Incubator incorporates a multi-layer safety system covering over-temperature protection, vibration stability, deviation alarm monitoring, and reliable long-duration operation — ensuring safe, unattended incubation across extended microbial culture and biochemical research protocols.
The BIS-2 incorporates an independent over-temperature protection system that monitors chamber temperature continuously and cuts heating power automatically if the temperature exceeds the safe upper limit — operating independently of the primary temperature control circuit. This protection is critical for a shaking incubator used in extended or overnight incubation protocols where heating element faults or sensor failures could otherwise cause undetected thermal damage to irreplaceable cultures, pharmaceutical samples, or biological research materials without operator awareness.
The BIS-2's shaking mechanism is engineered for stable, low-vibration operation that minimises mechanical noise and bench surface vibration at all speeds within the 40–250 rpm range. Low-vibration performance is a safety and practical consideration — excessive vibration can cause flask clamps to loosen during long-duration shaking, potentially resulting in flask displacement, spillage of biological materials, or loss of cultures. The stable mechanism also protects adjacent sensitive analytical equipment on shared bench surfaces from vibration interference during simultaneous operation.
The BIS-2 features an alarm system that activates when operating parameters deviate from the set conditions — including temperature deviations beyond the control accuracy threshold and shaking mechanism irregularities. In a shaking incubator used for extended, unattended microbial culture or fermentation protocols, early detection of temperature or shaking deviations via the alarm system allows operators to intervene before a deviation event compromises an entire culture run — protecting the value of cultures that may have been growing for hours or days prior to the deviation event.
The BIS-2 is designed for continuous, reliable operation across extended incubation periods — including multi-day fermentation studies, 48–72 hour microbial growth curve experiments, and overnight biochemical reaction protocols. The drive mechanism, temperature control system, and electronic components are specified for sustained duty cycle performance, ensuring that the BIS-2 maintains its setpoint accuracy and shaking stability throughout long-duration protocols without the performance degradation or mechanical wear that can cause mid-protocol failures in lower-specification orbital shaking incubators.
