Heating elements on support tubes radiating freely into the furnace chamber provide for particularly short heating times for these muffle furnaces. Thanks to their robust lightweight refractory brick insulation, they can reach a maximum working temperature of 1300 °C. These muffle furnaces thus represent an interesting alternative to the familiar L(T) ../12 models, when you need a higher application temperature.

• Port for thermocouple in the rear wall or in the furnace door

This table accepts up to five tube holders, each with a capacity of 24 x 50ml tubes. Each tube holder has its own clamp handle allowing it to be easily taken out of the incubator shaker and put on a clean bench while the other tubes keep on shaking. It’s also possible to shake microtiter plates on the EPFL-table, using Duetz 4-place coverclamps. If you have a Kuhner F-size tray (800 x 420mm), you can also clamp that on the table instead of individual holders.

For H2O pure types ASTM I + II.
OmniaTap is the ideal system when both pure water and ultrapure water are required, but in relatively small amounts. The ability to provide both types from a single system results from the combination of ultramodern purification technologies. These also make it possible to connect the system directly to a drinking water tap. A press on the dispenser button activates dispensing of ultrapure water type ASTM I via the digital dispenser control. The recirculation of the pure water held in the installed 10 litre tank keeps it permanently at type ASTM II quality. The pure water tank has a second outlet for feeding downstream end users.
Features
• OptiFill dispenser is standard
• TapWater set for direct connection to a drinking water tap
• 10-litre pure water tank has a pressure outlet
• Tank volume display in percent
• Simple and economical filter replacement
• Leakage sensor is standard
• Ready-to-use, including filter cartridges

This high speed centrifuge combines innovative technology with many decades of experience in the field of high speed laboratory centrifuges.
Positioned between laboratory centrifuges and ultracentrifuges, this refrigerated benchtop centrifuge features outstanding performance characteristics and excellent value for money.
High RCF values of more than 70,000 x g enable fast separation, even with microscopic particles and cell fragments. This makes the Sigma 3 30 especially suitable for high speed applications in fields such as cellular biology, molecular biology, diagnostics and clinical biology, nanotechnology, research and genetics.

What makes the Sigma 3 30KS high speed centrifuge so attractive?

The special drive system of the Sigma 3 30KS is specifically designed for use at very high speeds. This concept allows the high speed centrifuge to achieve RCF values above 70,000 x g with microlitre tubes.
This high speed centrifuge also has a high-performance refrigeration system. Centrifuging at temperatures below 0°C is possible, depending on the rotor and the speed.

A total of 20 rotors are available, along with a broad range of accessories. The tube capacities extend from 0.2 ml to 94 ml in fixed-angle rotors or 0.2 ml to 100 ml in swing-out rotors. Microtiter and deepwell plates can also be centrifuged.

Product options: Inert gas port, Biosafe fixed-angle rotors, RS 232 interface
