Applications
The VWR 315 is a standard benchtop magnetic stirrer used throughout chemistry, biology, and general laboratory settings for mixing solutions, dissolving solids, and maintaining homogeneous samples. Magnetic stirrers like this one use a rotating magnetic field beneath the top plate to spin a magnetic stir bar placed inside a beaker or flask — no direct mechanical contact with the sample vessel. The 4×4 stainless plate accommodates standard lab glassware up to about a 2-liter flask. These units are common workhorses in research labs, quality control, pharmaceutical, and educational settings for tasks ranging from simple buffer preparation to continuous reagent mixing. This style of compact single-speed-knob stirrer was widely used in labs from the 1980s through the 2000s and remains practical wherever a straightforward, reliable stirrer is needed.
This VWR Scientific 315 Magnetic Stirrer (Cat No 33918-246) has been inspected and is in good used condition. It was pulled from a working lab environment where it was in active use. The housing shows some scuffing and wear consistent with lab use, most visible on the rear panel. The stainless top plate and front controls appear intact.
