Porta-Stir Mag Stirrer

Porta Stir Mag stirrer

Perfect for our titrations.  Made in the USA.

Inexpensive alternative when size and convenience are considerations.  Low profile makes it perfect to use with a buret stand, eliminating the need to swirl the analyte during titrations.  No external power needed, the Porta-Stir will run for three days on a fresh AA battery.  2 7/8 inch x 2 1/2 inch base with a 2 1/4 inch platform works perfectly with our 250ml and 100ml disposable beakers, or our 25ml, 50ml, or 250ml Erlenmeyer Flask.  A 30 ml vial, stir bar, battery and instructions are included.  Stir bar is very small and easily lost.  An extra is included, spares available below.
