Benchmark Scientific Incu-Shaker CO2 Mini H3501, 46 L

Combine CO2 incubation and orbital shaking in one benchtop instrument for suspension cell culture. The Incu-Shaker CO2 Mini provides a 46 L chamber with temperature, CO2 and mixing control for culturing non-adherent cells.

Six-side heating and a low-speed internal fan distribute heat throughout the 316 stainless steel chamber without exchanging air with the external environment. The fan can be disabled for procedures requiring gravity convection. A beltless motor produces horizontal circular shaking with a 19 mm orbit.

Key Features

  • Temperature range of ambient +5°C to 60°C, adjustable in 0.1°C increments.
  • CO2 range of 0–20% with a dual-beam infrared sensor.
  • Shaking speed of 30–300 rpm in 1 rpm increments.
  • 19 mm orbital motion.
  • Timer from 1 minute to 48 hours, plus continuous operation.
  • 46 L chamber made from 316 stainless steel.
  • Includes a 9.5 × 11.5-inch platform with a non-slip rubber mat for low-speed shaking. High-speed mixing requires appropriate retaining accessories, sold separately.
