Perfect for our titrations. Made in 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 50ml 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.
