Thermometer adapter

Finally, you might put the thermometer in the thermometer adapter and suspend that, clamped gently by the rubber part of the adapter, not by the ground glass end. Clamping ground glass will score the joint. 

Add the 3-way adapter now (Fig. 69). Thermometer and thermometer adapter come later. 

All the clamps set up, all the joints tight—now where is that thermometer adapter ... 

Fill the distilling flask with the liquid you want to distill. You can remove the thermometer and thermometer adapter, fill the flask using a funnel, then put the thermometer and its adapter back in place. 

Read all about it. Ways of having fun with thermometer adapters have been detailed (see text accompanying Fig. 22). 

The polymerization is carried out in a 500 ml four-necked flask, fitted with stirrer, thermometer, adapter, and nitrogen inlet (see Fig.3.3).The individual parts of the apparatus are previously dried for 1 h at 120 °C,and while still hot are assembled as quickly as possible the whole is then evacuated and filled with PjOs-dried nitrogen three times.

A mercury-filled 6-mm o.d. glass tube with a platinum wire sealed through the lower end was used. The tube was bent to fit the contour of the flask. It was connected to the flask through a 24/40 standard-taper-joint Teflon thermometer adapter (Ace Glass, Vineland, NJ). Contact to the mercury was made with a platinum wire as shown (Figure 1). 

A Pasteur pipet clamped in an O-ring thermometer adapter served as a convenient, adjustable gas-inlet tube. The large end of the pipet was fitted with a small rubber septum, through which a syringe needle was passed for introducing the boron trifluoride gas. 

A thermometer adapted with a gas-addition tube may be purchased from Ace Glass Inc., Vineland, New Jersey (Cat. No. 5266). 

Choose a distilling flask carefully. If it s too big, you ll lose a lot of your product. If it s too small, you might have to distill in parts. Don t fill the distilling flask more than half full. Less than Vz full—you ll probably lose product. More than 14 full— you ll probably have undistilled material thrown up into the condenser (and into your previously clean product). Fill the distilling flask with the liquid you want to distill. You can remove the thermometer and thermometer adapter, fill the flask using a funnel, and then put the thermometer and its adapter back in place.
