Freeze Dryers - Christ

(DELTA 2-24)

Highest level of process-control and reproducibility for rapid, safe freeze drying of your high-quality products.

With 50 years of experience, Martin Christ GmbH is the leading producer of, not only routine-process freeze dryers, but also of a series of product-specific, highly specialized freeze dryers with far reaching potential. This line of equipment is distinguished by its innovative Lyo-Screen-Control (LSC) interface, its exceptional design and the most advanced level of refrigeration and vacuum technology. The freeze dryers are available as laboratory freeze dryers with cylindrical drying chambers and pilot systems with rectangular cross-section drying chambers. A practical and diverse collection of accessories permits a wide range of tasks. Outstanding products, superior technology and full customer support. Applying advanced processes to valuable products requires specific system configuration. We offer extensive advice in selecting a system and, on request, will run a freeze-drying test in our applications laboratory. Martin Christ's high-quality freeze dryers are equipped with a modern, intuitive interface known as the Lyo-Screen-Control(LSC). This interface is used throughout our line of laboratory and pilot freeze dryers. It allows for up to 30 different drying programs with even the smallest machine as well as for the connection to a PC for process documentation and process control.

The best in specific systems and process monitoring.

Freeze dryers are increasingly being used for small batches whose production involves detailed information to create validation documents (IQ/OQ documentation) and to prepare monitoring tools that ensure flawless product quality. We not only use standard measurements of product temperature and pressure, but also measurements of electrical resistance (Lyo-control) and weight-change (weighing cell) during the drying process. Optimal product safety can thus be guaranteed. Unacceptable structural changes including the collapse of the matrix, i.e. possible cross-contamination during the drying phase, can be avoided with confidence..

Laboratory Freeze Dryers

The optimal system for advanced applications:
• compact, high-performance laboratory and technical equipmentrequiring minimal space
• modular systems permit capacity expansion with a wide varietyof accessories
• complete processing of entire freeze-drying cycle in ice condenser chamber, program controlled, if desired, from-30°C (prefreezing) with single-stage compressors, to -50°C(prefreezing) with doublestage compressors
• innovative, easy-to-use interface LSC with PC connection for process control and documentation
• freeze-dryer system fulfills FDA and cGMP-Guidelines, interfacefulfills the current requirements according to GAMP, Lyo-software LPC-16 also meets US CFR requirements
• drying chamber is located directly above the ice condenser chamber; maximum cross-sectional area results in high sublimation performance and shortest possible process-time
• ice condenser chamber with inner condenser coil of high- quality steel allows for efficient vapour deposition
• thermal insulation of ice condenser chamber avoids power loss and eliminates build-up of water condensation
• ice condenser can be checked visually

Pilot Freeze Dryers

The highest level of research and development for newproducts.

The Epsilon 1-4 / 2-4 and Epsilon 1-6 D / 2-6 D set the standard for pilot systems of the highest quality and performance. They share a geometrical likeness with large production machines and use similar temperature-controlling systems. The Epsilon 1-4 / 2-4 units have an ice condenser temperature with a minimum of -55°C and -85°C respectively and is available with one shelf with 0.11 m2 usable surface area. The anodized Aluminium shelves can be directly heated or cooled, making the Epsilon 1-4 / 2-4 suitable for both experimental and routine freeze drying. The two larger models, Epsilon 1-6 D and 2-6 D, are characterized by their drying potential on a maximum of four shelves with an area of 0.28 m2, their distance between shelves can reach 75mm(with three shelves). Due to the temperature control of the stainless steel shelves (via a synthetic heat-transfer medium), these pilot systems fulfil the highest standards of the pharmaceutical and biotech industries. New cooling techniques allow for shelf temperatures of -40°C and -55°C/-70°C (pre-freezing) in the very compact chambers of the Epsilon 1-4 and 1-6 D and the Epsilon 2-4 and 2-6 D, respectively. This permits extremely sensitive pharmaceutical and biotech products, e.g. amorphous structures with a low glass transition point, to be freeze dried safely. These pilot dryers are also available with liquid nitrogen cooling. Simple, process-specific documentation is possible on all systems as a result of the new Lyo-Screen-Control and Lyolog interface. The innovative weighing cell provides the ability to monitor freeze drying in vials and trays, in addition to the standard measurements of product temperature and pressure. An added option is the Windows-based LPC-16 software for PC process control and documentation. LPC-16 is widely used in large freeze-drying production systems and follows the GAMP and cGMP guidelines. Other cGMP guidelines are also followed including maintenance and surface guidelines. The systems can be H2O2 sterilized and can be delivered with an Installation/Operation qualification. All systems are very flexible; all are available with manual stoppering devices and additional manifolds for lyophilization in round bottom flasks. These systems will contribute to the success of your small batch production and product development.

• rotor capacity 216 x 1.5/2.2 ml tubes up to 12 x microtiter plates or 4 x deep-well plates
• stainless steel/glass compound cover with window (corrosion proof)
• high-performance drive system, 1.550 min-1 (500xg f. micro tubes) prevents bumping and foaming (e.g. with DCM)
• practically tolerant to imbalance (> 50 g)
• c hemical resistant diaphragm pumps (2m3/h suction, 9 mbar final vacuum), standard, vacuum system with lower vacuum and vacuum controls, optional, chemical hybridpump for solvents with high boiling points (e.g. DMSO)
• recommended use with 4 liter cooling traps due to high volume evaporation (-50°C, -60°C, -90°C or -105°C)
• flexible use as vacuum drying chamber through easy dismantling of rotor shaft

Rotational-Vacuum-Concentrator 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.
