Product Description
Seal a plain-stem thermometer into your distillation head without grease, tape or a separate thermometer adapter. The threaded BEVEL-SEAL top uses a compression cap and O-ring to give a vacuum-tight fit, so readings stay accurate even under reduced pressure. It is a practical upgrade for any lab that runs reduced-pressure work.
This listing is for Kimble catalog number 274960-0000: BEVEL-SEAL 75° Connecting Distillation Adapter, 14/20 mm. The threaded top is a modified GPI 13-425 finish fitted with an open top compression cap and a size 010 FKM O-ring; cap 410119-1307 is rated to 200 C. Inner standard taper joints are angled at 75 degrees. Glass is low extractable 33 expansion borosilicate, and the adapter is offered in 14/20, 19/22 and 24/40 joint sizes. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
