Completed Projects and Containment Solutions
Ravona Isolator technology is ready for adaptation with robotics and some of the manipulator's arms on the market that is already electronically and mechanically controlled.
The systems require custom fittings and covers to protect the moving parts and the products inside these chambers.
Many of these Isolators/Glove boxes are widely used in advanced electronics and pharmaceutical facilities.
In the Pharmaceutical industry, there are over 200 aseptic filling lines using isolators and industry leaders and manufacturing engineers continue to embrace enclosures.
Ravona’s Drum Sampling System enables pharmaceutical companies to easily and safely sample potent and sensitive substances. The System is implemented in logistical and distribution centers. The System is most suitable for potent substances as well as oxygen/humidity/light-sensitive substances. Ravona’s Drum Sampling System eliminates the use of awkward solutions such as pressure suits or exposure of the user or substances.
Ravona’s Drum Sampling System consists of one working chamber and two airlock systems. The containers are inserted into a smart airlock system, enabling the user to sample the substances in a controlled environment.
Ravona’s Drum Sampling Systems are custom made to fit various types, sizes and shapes of barrels and other containers. The Chamber and airlocks are made of SS316, fully cleanable with round corners and surface polish of Ra<0.4. The system uses a “Guillotine” type door to allow easy operation and space-saving. The system is fully PLC controlled with pre-conditions alarms and warnings. Full cGMP documentation is provided.
Ravona’s Drum Sampling System was first developed for Teva Pharmaceutical. This is another example of our customized innovative solutions.

RABS Restricted Area Barier System
Restricted area barrier system:
RABS is a type of barrier system for aseptic processing of pharmaceutical products that reduces or eliminates interventions into the critical zone.
In practice, its level of contamination control lies somewhere on the spectrum between a conventional cleanroom aseptic processing and an isolator.
The ISPE has decided that in order to be classified as a RABS, a system must include the following elements:
• Properly designed equipment
• Management oversight
• A quality system in place
• Proper surrounding room design to maintain ISO 5 in the critical zone
• Proper gowning practice
• Proper training
• Initial high-level disinfection with a sporicidal agent
• Proper SOP's for rare interventions
• Appropriate line clearance
• Documentation of event.
Special design portable isolators.
With size limitations and the need for few portable isolators, Ravona engineers produces the ultimate solution for the clients specific requirements in this project.
• Properly designed equipment
• Management oversight
• Built in special tray system with an under the chamber portable water tank.
• Proper quick connections for supplies to accommodate full portability.
• Special pneumatic system assisting in water tank lift and seal.
Adding containment to an existing sieving machine.
Existing manufacturing process machine may be needed for the processing of upscale potent pharmaceutical ingridiance.
Changing the machines in the process to different machines that are contained may pose problem of initiating the whole process validation.
Ravona has proven that such conversion of existing machines (sieving, grinding, micronizing ,etc.) can be achieved in a cost effective solution.
Being a custom made product manufacturer ,our engineers examine all possibilities in applying a containment to an existing equipment that withstand the standard tests and still be ergonomic to the user.

Production folders paperwork venting work station
Paper work taken to production suites involving powders are exposed to residues of powders in between the papers.
At the end of the paperwork usage, the folders are placed in plastic bags and taken to the company archives.
Complains from archives personnel of physical reactions lead to the development of this work station .
Hanging the folder in the provided clips , and turning on the powerful sucking blower , creates turbulence air flow that flips the paper and the powder residue is sucked into the bottom of the workstation through a pre filter and a HEPA filter .
Filters can be easily and safely changed when needed.

Instruments/apparatus/machinery integration into a containment enclosure
There are many obstacles on the way to achieve full containment and fully sealed containment enclosure with all the equipment integration .
A very high level of expertise, knowledge and know how is required to successfully install and integrate different type of instrumentation into a containment enclosure.
In many cases , apparatus used for non potent material , needs to change its usage for potent material handling.
There are two options :
1. To purchase new equipment (same equipment )with containment enclosure already in place , this option may be a very expensive option.
2.To have the existing equipment integrated into a containment enclosure by professional company such as Ravona Pharma.
Ravona glove boxes/isolators engineered alone or with integrated process equipment including:
mills , blenders, weighing scales, reactors, rotary-evaporators, vacuum ovens, Nutsche filters and more.
Part of the process may require a mock up building , such mock up study may prevent users ergonomic
Problems and equipment access through glove ports and gloves.
It is essential to have the actual equipment users actively involved and assure the equipment can be easily used and
Another issue that is very important and often overlooked is size allocation for containment enclosures.
Containment enclosures (glove boxes/Isolators) can get large and consume big floor space.
With Ravona Pharma glove box isolators standing testing , our clients have the potential to handle the most potent products available on the market. Ravona’s high containment products have been designed to fulfill a range of applications including: dispensing and sampling, charging, drum filling, off-loading (continuous liner system), milling and micronizing, sieving and tray drying.
