Alu-Rings with hooks
For cones and sockets to be used with springs for the safe connection of conical ground joints. No breakage of glass hooks.
Bellows, PTFE
Strainless connection of ground joint equipment; for compensating vibrations from vacuum pumps; for length compensation of heated columns; angular misalignment.Made of PTFE, with sharp folds and sealing rings on the outside; maximum deflection: 120°.
BUDDE - joint grease, silicone-free
For all glass joints. Transparent, vacuum tight, water washable and water soluble. Maintains practically the consistency between -30 °C and 200 °C, non-solidifying. Compatible with most elastomers. Tube of 80 g.
Clips for joints, POM
Flexible jawsExcellent chemical resistanceHigh mechanical strength
Conical joint clips, "Safety Clip" type
POM. Will not scratch glass surfaces. Also suitable for use with sleeves with grip collar, due to adjustable jaw opening. Outstanding chemical resistance. Operating temperature up to approx. 150°C.
Disposable ground joint sleeves, PTFE
Outstanding chemical resistance at operating temperatures from -200 to 260 °C, only 50 µm thickness, the sleeves fit like a second skin without adding bulk, without grip collar, simplifying use of joint clips.

Made of stainless steel 304. For spherical ground joint connections. With set screw.
LLG-Joint clips, POM, for conical ground joints
For an easy and safe fixing of jointed glassware.
PTFE sealing rings for jointed glassware
An effective alternative to common PTFE joint sleeves and PTFE stoppers.Air leakage <10-8 to 10-6 mBar l/s (vacuum and pressure)Solvent leakage from containers < 0.1 to 0.03mg/dayTemperature range: -196 to 300°C
Rotating joint grease, silicone-free, Alsirol
Silicone-free stopcock grease. No silicone derivatives, polymerisation or gumming. Excellent adhesion and viscosity. Stable grease film enables safe, long term use. Low heat-up occurs during rotation even if operation is continuous. When sealing glassware systems with glass and metal stirrers and shafts Alsirol protects rotating, precision-ground sockets and stirring shafts against glass abrasion. Also suitable for lubricating rotating metal and glass components. Acid and alkali resistant. For use under vacuum and high vacuum. Biodegradable. Non-toxic in normal use.
Silicone oil freeing agent M Korasilon®
Ready for use, in 400ml spray can. Solvent-free. Improved lubricant properties. With point and surface nozzle. Maximum operating temperature: 350°C.Warning: The spray propellant is flammable and potentially explosive.
