Globe Scientific GTR-AS Adjustable Speed Laboratory Tube Rocker with Silicone Insert

The Globe Scientific GTR-AS and GTR-2-AS are precision adjustable-speed tube rockers designed for efficient laboratory tube mixing and gentle sample agitation. Featuring a rocking motion and an adjustable speed range of 0–30 RPM with a fixed 30° tilt angle, these benchtop tube rockers provide consistent mixing performance suitable for molecular diagnostics, bioprocessing, and synthetic biology protocols.

Key technical features include:

• Silicone inserts fitted to securely hold tubes ranging from 0.5 mL to 10 mL, facilitating versatile sample mixing in biotechnology and molecular biology workflows.
• The GTR-AS offers a single tier platform with a working area of 190.5 x 127 mm (7.5 x 5"), supporting a maximum load capacity of 1 kg (2.2 lbs).
• The GTR-2-AS incorporates a dual-tier rack to double sample capacity without increasing bench footprint, maintaining the same dimensions per tier and load capacity.
• Operates on 100–240 VAC, 50–60 Hz power supply with a modest power consumption of 15 W, suitable for standard laboratory environments.
• Compact design with dimensions 295 x 160 x 120 mm (11.6 x 6.3 x 4.7") for GTR-AS and 295 x 160 x 165 mm (11.6 x 6.3 x 6.5") for GTR-2-AS and weight between 1.8–2 kg, optimizing benchtop space in cell imaging, fluorescence analysis, and biomanufacturing facilities.
• Suitable operational conditions include temperatures from 5°C to 50°C and relative humidity up to 80% RH (non-condensing), ensuring reliability in controlled research environments.

The Globe Scientific adjustable speed tube rockers are essential for reproducible sample mixing in molecular cloning workflows and biopharmaceutical production pipelines, widely used in cell culture and synthetic biology research applications. Their precise speed control and ergonomic design make them a popular choice among molecular biology researchers and clinical diagnostics laboratories.
