Company Profile

ManufacturerZIRBUS Technology GmbHHe is the founder of freeze-drying technology in Germany, founded in 1984 and headquartered in Bad Grund. The company has been focusing on the research and development of freeze-drying systems for more than 40 years. It is a company that applies nitrogen cooling technology (-80 ℃ level) to laboratory freeze-drying equipment. Its factory achieves 100% independent production of core components (compressors, cold traps, etc.). Our products have passed ISO 9001 certification and FMP-FDA compliance verification, serving the global pharmaceutical, biotechnology, and food science fields. Our clients include top companies such as Pfizer and Nestle.

Product Type

VaCo2 belongs toLaboratory desktop freeze dryer series， ZIRBUS core products are divided into four categories:

1. Laboratory Basic Type(VaCo 2/5/10, suitable for small batch research and development)

The VaCo2 series includes two sub models:

1. VaCo 2-50Standard low-temperature type (low-temperature -55 ℃, cold trap -50 ℃)

2. VaCo 2-80Deep freezing type (low temperature -85 ℃, cold trap -80 ℃)

3. add-on suite：

1. 6-position stainless steel manifold (compatible with ampoules)

2. Transparent freeze-drying chamber (Ø 200 × 360mm, 8 external bottle positions)

Product Introduction

VaCo2 achieves efficient sublimation drying through nitrogen cooling technology and modular cold traps:

core structure：

oCold trap systemVertical stainless steel coil (volume 5.7L, Ra ≤ 0.8 μ m electrolytic polishing)

oRefrigeration unitAir cooled compressor (fluorine free environmentally friendly working fluid, GWP<1)

ocontrol moduleMicrocomputer touch screen (real-time display of temperature/vacuum curve)

oMaterial standardsFull 316L stainless steel contact surface (resistant to acid and alkali corrosion)

·

working principle：
After pre freezing the sample, place it in a cold trap and use a vacuum system (maximum vacuum ≤ 0.01 mbar) to directly sublime the ice crystals; The nitrogen cooling technology improves the refrigeration efficiency by 30% compared to traditional Freon refrigeration, and the ice capture rate reaches 140g/h. The drying process supports programmed temperature control (PID algorithm) to avoid sample collapse.

Advantages and Features

1. Breakthrough in drying efficiency：

oNitrogen cooling technology has a cooling rate 40% faster than traditional compressors (only 25 minutes at -80 ℃), and a freezing rate greater than 140g/h

oThe design of the cold trap coil increases the effective surface area by 50% compared to plate heat exchangers, and the ice capture capacity is increased to 3kg (the industry average for cold traps of the same volume is 2kg)

2. Wide compatibility of samples：

o-80 ℃ deep freezing supports organic solvents (such as tert butanol) freeze-drying to avoid eutectic point collapse

oTransparent freeze-drying chamber (optional) for real-time observation, with a partition spacing of 55mm that can be adjusted to fit different containers

3. Innovation in Intelligent Control：

oMicrocomputer stores 50 sets of program formulas and supports RS232 data export (compliant with 21 CFR Part 11 audit trail)

oVacuum sensor automatically triggers defrosting, saving 90% time compared to manual defrosting

4. guarantee：

oAll stainless steel flow channels have passed ECOLAB certification, with endotoxin release<0.001 EU/mL

oSilicone free sealing design (made of fluororubber material) to avoid contamination of biological samples

Main applications

1. Biopharmaceutical R&D：

oDevelopment of monoclonal antibody freeze-dried powder (-80 ℃ cryogenic retention of protein activity, residual moisture ≤ 1%)

oPre freezing of vaccine adjuvants (with a temperature control accuracy of ± 1 ℃ for the partition to avoid phase separation)

2. Food Science Innovation：

oProbiotic freeze-drying protection (nitrogen cooling to prevent ice crystal damage to cell membrane)

oTruffle flavor preservation and drying (real-time monitoring of color changes in transparent warehouse)

3. Preparation of nanomaterials：

oFreeze drying of liposome nanoparticles (0.01 mbar vacuum suppression of aggregation)

oSolvent removal of metal organic frameworks (MOFs) (compatibility with tert butanol)

4. Cultural heritage protection：

oAncient book water immersion rescue (partition+40 ℃ gradient heating drying to prevent paper brittleness)

oPreservation of archaeological biological specimens (capturing volatile degradation products in cold traps)
