Fits neatly around flasks with side-arm tubing connections
Rings fits neatly around the neck of filtering flasks with side-arm tubing connections. No need to disconnect the tubing and possibly compromise the process. The open ring, made of lead and covered with Vikem® vinyl coating to protect glassware, is flexible enough to be pulled apart to accommodate a wider vessel. Available in four diameter/weight combinations to meet the needs in your lab.
