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.
