Overview

The Ultracentrifuge T-1100 is a milestone in the state-of-the-art of centrifugation, thanks to a flexible architecture approach it can be implemented as a stand-alone machine and upgraded to a sophisticated PC-remote-controlled T-2100 according to your laboratory needs.

Specifications

Drive

• Maintenance-free, direct drive

Parameter Display

Digital actual- and preset-value displays for:

Safety System

• Error indicators with audible alarm
• Message panel featuring operating modes, parameters, status, errors and file indicators
• Automatic restart after power or water failure when speed is ≥ 1,000 rpm, if the speed is lower the machine brakes to zero after power restart
• Recall button for lowest rotor speed, rotor temperature and interruption time after an “auto restart” following a power or water failure
• Photoelectronic overspeed safety system with early max. rotor speed check
• Dynamic, imbalance control effective up to top speed
• Locking of keiyboard and zonal centrifugation by a key switch
• Soft-touch keyboard with control indicators
• Connection for external central alarm “units”
• Bio-hazard protection kit (option)
• Automatic rotor overspeed detection

Mode choice

• 3 chamber preconditioning modes:

- drying

- precooling

- drying and precooling

• 3 centrifugation modes:

- normal

- zonal

- step

• 3 operation submodes :

- slow on/off

- brake on/off

- option (Reduced vacuum level)

• Setting of run-time, rotor speed and rotor temperature for up to 5 steps
• Direct acceleration program for low mass rotors with rotor discrimination
• Preselection of run-time up to 99 hrs, 59 min or hold
• ω²t integrator up to 99999 x 10 ⁸ or to 10 ³⁰
• Quartz clock for delayed self-start up to 99 hrs, 59 min

Programmable files
