Introducting the brand new ST1R™ overhead stirrer from Waverly®. Like with our other products, we've designed a one-size-fits all model ('super model'). In other words, we only make one model (called ST1R™) that is the best of all worlds: most capacity for its size, most power (torque) in it's class, longest lasting (premuim brushless motor), latest digital tech, and of course best looking! So, because we just make the one model, we can be very cost efficient with manufacturing, and in turn you can get the Ferrari for the price of a Kia!
The new overhead stirrer from Waverly® Scientific products is a universal overhead stirrer ideal for many different applications. Perfect for stirring, mixing, homogenizing liquids/solids including high viscosity substances.
Waverly® has designed this stirrer for the modern laboratory. It is compact, lightweight and has a sleek design. Featuring a sharp LED digital display covered by tempered glass cover (like an iPhone).
We've consolidated our desgns into one model only, ST1R™, which happens to be the top model with the best specifications. By consolidating into one model we are able to leverage economies of scale so that we can offer the best model with a price that is competitive with any other brand/model in it's class.
