Frequently Asked Questions
What is the difference between GHS-550S and GHS-550S-UK-EU?
Both stirrers are functionally identical with a 7 x 7 inch glass ceramic top plate. The GHS-550S operates at 100-120V for North American outlets, while the GHS-550S-UK-EU is configured for 200-240V UK/EU power, both at 50-60Hz.
Does this stirrer include a heating function?
No. This model is a dedicated analog magnetic stirrer without integrated heating. Choose it when you need mixing alone; a separate hotplate-stirrer is required for combined heat-and-stir applications.
Why is the top plate made of glass ceramic?
Glass ceramic provides a smooth, non-porous surface that resists aggressive reagents and cleans easily. It withstands aqueous buffers, dilute acids and bases, and many solvents without staining or degradation.
What size vessels does the 7 x 7 inch plate accommodate?
The flat 178 x 178 mm surface supports beakers, flasks, and bottles of varied footprints, making it suitable for routine bench-top volumes from small samples up to liter-scale vessels with an appropriate stir bar.
