Stillheads, ground glass joint, with integral Liebig condenser
Manufactured from borosilicate glass 3.3 which is resistant to heat and almost all chemicals. With liebig condenser and socket NS14/23 for distillation thermometers.
Stirrer bearings with cooling jacket, DURAN® tubing
Made of DURAN® tubing. Stirrer bearings with NS cone and cooling water connections (thread GL14), bearing surface ground and polished.
Stirrer bearings with dynamic double seal
Stirrer bearings for applications under vacuum or under slight overpressure. With extended guidance for reduced vibrations and a longer lifetime. Material: borosilicate glass 3.3 (closure), PTFE (sealings)
Stirrer bearings with GL male thread, DURAN® tubing
Made of DURAN® tubing. Other materials used: PTFE (bearing), silicone (gasket) and stirrer guides, GL male thread. Cone size 29/32. Guide bore 10mm i.d.
Stirrer Bearings, PTFE
The sealing rings on these bearings ensure a perfect sealing. The ground joint no longer sticks, the danger of breaking is reduced and the cone can be removed easily from the socket. A special gasket made of PTFE and an FPM o-ring which is compressed by a GL screw cap provide a good sealing of the stirrer shaft. This gasket can be exchanged after wearing. Suitable for vacuum, perfect bearing for stainless steel, glass and BOLA Stirrer Shafts.
Stirrer bearings, PTFE for Reactor lids
With NPT screw thread. Universal chemical resistance. With special gasket made of PTFE and an FPM o-ring for optimal compression of the GL screw cap made of PPS. The media is only exposed to PTFE. With hexagonal gripping surface in standard wrench size. Temperature resistant from -15 to 200 °C.
Stirrer with stirrer bearings, DURAN® tubing
Made of DURAN® tubing. For round bottom flasks 250 to 2000ml. Stirrer shaft, with PTFE stirrer blade and fixing screw. Seals vacuum stirring apparatus gas-tight to 10-3 mbar up to a permanent load of 800rpm.
