Whether you’re suspending blood samples, culturing cells, or simply mixing reagents, precise and consistent agitation is key. Two new rotary mixers—RSM7DC Rotary Tube Mixer with Disc and RM4 Medium Rotary Mixer—are raising the bar for lab mixing efficiency, flexibility, and quiet operation.
RSM7DC: Compact, Customizable, and Quiet Operation
The RSM7DC Rotary Tube Mixer with Disc is a lab tech’s dream for small to medium-scale sample handling. Designed for precision and adaptability, the RSM7DC features:
-
Variable speed control from 10 to 60 RPM
-
Fully adjustable disc angle – from horizontal to vertical
-
Quiet operation, ideal for shared lab environments
-
Customisable discs, allowing tailored solutions for your specific tube sizes
-
Accommodates small to medium tubes and bottles
The RSM7DC shines in biological and clinical settings, with its end-over-end motion perfect for suspending blood samples, aerating cultures, or general-purpose mixing. Unique to its design, users can load and unload samples mid-operation thanks to its easy-to-stop disc and removable locking screw. For heavier, off-balance loads, a central locking screw adds extra stability.
Key Specs:
- Power: 12VDC
-
Dimensions: H415 x D255 x W300 mm
-
Weight: 5 kg (with disc)
-
Supplied with 20 threaded inserts and custom-fit clips
If you need a quiet, versatile mixer with customizable capacity, the RSM7DC fits the bill—and your benchtop.
RM4: Heavy-Duty Precision with Intelligent Control
Stepping up in size and control capability, the RM4 Medium Rotary Mixer is engineered for larger capacity and programmable precision. Ideal for research environments that demand repeatability and automation, the RM4 includes:
-
End-over-end mixing with a smooth microprocessor-controlled drive
-
Three user-defined preset programs for automated routines
-
Ultra-quiet brushless AC motor for silent, long-term operation
-
Interchangeable clamp system for bottles, flasks, and test tubes up to 250mm long
-
Digital display with optical speed feedback and timer control (0–99 minutes or hours)
The RM4 is a versatile solution for clinical testing, molecular biology, and biochemistry labs. It supports up to 4 kg of evenly loaded materials and boasts a range of safety features, including a motion-interrupt cut-off for added lab protection.
Key Specs:
-
Power: 240VAC / 130 watts
-
Speed range: 6–57 RPM
-
Mixer control: Solid-state with optical feedback
-
Dimensions: W455 x D400 x H335 mm
With its programmable memory and broad clamp options—including 3-prong and spring clip adapters—the RM4 is the go-to choice for labs managing multiple mixing protocols or handling a diverse array of container types.
Which Mixer is Right for You?
-
Choose the RSM7DC if your lab needs a compact, versatile, and quiet mixer for light to moderate workloads, especially involving tubes and small bottles.
-
Opt for the RM4 if you’re dealing with heavier samples, need programmability, or require the flexibility to accommodate a wide range of container sizes with precise, automated control.
Both mixers are designed with user convenience in mind and can be customized to suit unique lab applications. Whether you’re running standard blood tests or complex molecular assays, these two new rotary mixers offer reliable performance to keep your lab moving—literally.
