Separatory Funnel: Glass: PTFE Stopcock: 1000ml Polyethylene Stopper

 

1000 ml conical separatory funnel is made of hand blown borosilicate (heat resistant) glass with PTFE stopcock (valve) and a polyethylene stopper. It is the largest one to the left in the picture. PTFE stopcocks are less likely to seize up than glass to glass fittings and do not require expensive lubricant therefore reducing the risk of contamination. These are hand calibrated and accurate to better than 1% total volume. You are receiving a 1000mL funnel - the same shape as the 250mL that is pictured.
