K24 Vacuum Mixing Stopper

Description

Stir Under Vacuum Without Losing It

Reduced-pressure chemistry needs agitation, and agitation needs a shaft through the flask joint. This patented stopper seals both: the taper joint against the flask, and the rotating shaft against the atmosphere.

How the Seal Works

• The joint: Twelve thin Teflon fins compress against the TS24 glass taper, sealing without grease
• The shaft: A Teflon cup seal in a gland packing arrangement, riding an O-ring, seals the rotating shaft
• The result: Reduced-pressure stirring for distillation, degassing, and air-sensitive work

Keep It Sealing for Years

Gland seals are replaceable in a four-pack, and internal parts are available separately, so the stopper stays in service through years of joint cycles. Backed by our One-Year Total Care Warranty covering parts, labor, and specification compliance.

Working in TS29 glassware? The K29 Vacuum Mixing Stopper is the same patented seal sized for 29/42 joints.
