1 1/2 inch Oval-shaped PTFE Coated Magnetic Stir-bars for Lab Type Mixers

Description

Six(6) new PTFE covered stir bars for use in beaker or jar with magnetic stir machine. Size is approximately 1 1/2" x 1/2" (40 x13mm) each. Weigh approximately 0.4oz (10g) each. I am not a scientist so size/weights are to my best I can do with my postage scale. Never used. I ordered these about 1 year ago but they are too big for what I need. Please pay with new eBay payment.          DO NOT PAY WITH PAYPAL
