LSC plus controller
New controller LSC plus improved version with color touch screen
The application of new forward-looking technologies - the use of a high performance digital signal processor, a high resolution colored TFT-display and the touch functionality – give the space for an easy future upgrade of functions and features. New ideas and experiences of customers, distributors and our own research group can be smoothly embedded. The coloured touchscreen and the improved „intuitive to use“ - menu structures provide an optimum selection of different functions.
Features:
- colored touch screen with mimic diagram
- „one screen“-summary of set values
- graphical summary of programs, similar to LPC-32-software
- program templates for different products
- data storage on USB memory
- detailed message information
- operation structure like LSC
- different scale units °C/°F, mbar/hPa
- access-protection by password
- integration in network structures
- multi language user interface
- PC based simulation available
CHRIST RVC SpeedDry 2-33IR
Fastest possible Sample Concentration and Drying !
This newly developed CHRIST-vacuum concentrator SpeedDry 2-33IR is particularly suitable for gentle concentration of DNA/RNA, proteins, and similar analysis preparations at the workplace. The versatile rotor program provides a high sample capacity, e.g. from 216 x 1.5 ml reaction vials up to 12 x microtiter-plates or 4 x deep-well plates. In addition, large sample volumes, e.g. 100-ml-tubes that are used for the screening of active substances can be quickly concentrated thanks to the efficient energy supply with halogen IR lamps.
The innovative drive system with its powerful external rotor motor, the contact-free, central rotary coupler, and direct power transmission all guarantee safe operation even in the event of high unbalance.
The user-friendly CDplus control unit provides a quick overview of the current operating parameters. Heating temperatures between +30°C and +80°C and, of course, also the entire pressure range of the vacuum pump can be selected either manually or controlled by a program, also freeze drying possible.
Features:
- Particularly solvent-resistant unit with a stainless-steel chamber, safety glass lid and magnetic drive without a shaft exit to the outside. Suitable for DMSO, ACN, TFA.
- CDplus control unit with a ramp programming function for pressure and temperature (16 programs max.).
- Halogen IR lamp provide optimal energy input for fastest possible evaporation.
- Control of the energy supply as a function of the sample vessel temperature, plus an additional measurement of the product temperature in order to avoid thermal damage.
- Robust, non-contact measurement data transfer (Triple TMM) from the rotor to the control unit.
- Precise vacuum control in both directions (air injection) for reproducible processes. High-performance vacuum pumps with final vacuum of < 0.1 mbar allow dual-step process "Evaporation and Freeze Drying".
- Determination of the end of the drying process (pressure increase test) for automatic operation.
- Variable speed for substance mixtures that tend towards a delay in boiling.
- Central control of the entire system consisting of the RVC, cooling trap (LDplus/LSC), and vacuum pump (including a warm-up/cool-down function).
- Multilingual user interface (German/English/French).
All units are "Made in Germany" within ISO 9001 certified series production. In addition to this, S-Biotech Kft. further guarantees its supplyings within ISO 9001 certified activities and provides a qualified technical and application service.
Wireless Product Temperature - Measuring "WTM" in Freeze Drying
Initial situation:
The product temperature is considered as an essential criterion for monitoring an control of the freeze drying process, in fact during freeze drying as well as during main and final drying. As measuring should be carried out in several - often small - vials, conventional wired sensors cause considerable handling problems ("spaghetti").
Every now and then sample vials tip over when placing the sensor and the product contaminates the freeze dryer.
Moreover, for wired sensors it is necessary to place sockets incl. wiring within the drying chamber, which makes cleaning difficult.
For production units with automatic loading systems, placing of conventional sensor is almost impossible. This applies espacially in connection with slot doors and isolator technique. Such drying cycles are mostly run without product temperature measuring, relying upon the results of validation runs.
("Wireless Product Temperature Measurement") WTM
The solution:
Motivated by the PAT ("Process Analytical Technologies") initiated by the FDA we have broken new ground. In cooperation with company IQ-mobil the wireless temperature measurement system WTM ("Wireless Product Temperature Measurement") was developed, designed to eliminate the above disadvantages. The wireless, energy autarkic sensors are placed manually or automatically when filling the product vials or dishes; during the whole lyophilization process they report the product temperature to the system control.
Functional principle:
- Energy supply of the sensors by means of a radio frequency within in the 2,4 GHz band
- Intermediate storage of energy by stimulation of a quartz crystal
- Highprecision temprature-dependent quartz-detuning of oscillation frequency
- Transmission of frequency modulation and temperature
determination via the evaluation electronic.
Additional highlights:
- due to the "passive layout" without battery as well as lowest power level, the product temperature is not falsified
- several sensor frequencys for monitoring at different sensor positions
- Determination of user-defined sensor positions for automatic loading/unloading
- interference proof radio transmission worldwide at 2,4 GHz
- by means of active change of frequency a stable signal at every position is granted even in stainless steel freeze dryers.
- Accuracy +/-0,5 K, max. +/-1 K
- covers the entire process (temperature range -60°C ... +140°C)
- wireless transferred data or process monitoring an -control are available in the Martin Christ process control system LPC
