Stopcock grease, silicone-free
For lubricating burette stopcocksGood acid- and base-resistanceOperating temperature range -40 to 320 ºC
Sleeves with ribs, PTFE
For use with ground glass joints. Suitable for vacuums up to 0.1mbar. Reusable and long lasting. The sealing ribs grip on the inside wall of the glass socket, sealing without the need for grease and enabling the cone to be freed easily when required.
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.
Joint clips KECK, POM, for conical ground joints
Melting point 175 °C. Excellent chemical resistance. Rigid. Heat resistant up to 150 °C, sizes colour coded.
Joint clips KECK, POM, for spherical ground joints
Melting point 175 °C. Excellent chemical resistance. Rigid. Heat resistant up to 150 °C, sizes colour coded.
Fork clamps for spherical joints
Material: stainless steel. For spherical ground joint connections. With set screw.
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.
Ground joint clamps, POM
For securing the link between socket and cone.Very good chemical resistanceMax. operating temperatur 150 °CColour coded sizes
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
Sleeves, PTFE, disposable
Seals without grease - no grease residues are left in the analysis. Excellent chemical resistance. Can be used in temperatures from -200 to 260 °C. Wall thickness only 0.05 mm. Wide range of applications, also suitable for vacuums down to 0.1 mbar, e.g. for rotary evaporators.
Sleeves, cone joint, PTFE
With knurled gripping ring at the top of the cone for easy removal. For gas, liquid and vacuum-tight cone joint connections with sizes as outlined below. Reusable. With reinforced external ribs for a high-vacuum tight seal (leakage rate: < 1x10-4mbar x I x s-1). No joint sealant or grease required.

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.
KECK™ Clips for conical joints, spring steel
For applications with very high temperatures. Easy to fit, dimensionally stable.
LLG-Fork clamps for spherical joints
Made of stainless steel 304. For spherical ground joint connections. With set screw.
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°.
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.
Joint grease, K.W.S
Without silicone. Designed as vacuum and high vacuum grease. No silicone derivatives, polymerisation or gumming. Excellent adhesion and viscosity. Acid/alkaline resistant. Locked joints can be loosened by brief, gentle heating. Can be used to make temporary glassware repairs. Biodegradable. Non-toxic in normal use.Working temperature range:-40 ... 200 °C, to 10-5 mbarVapour pressure:0.00001 mbar
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.Working temperature range:-40 ... 200°CVapour pressure:0.00001 mbar
BUDDE - joint grease
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 80g.
