  • Flow Sciences, Inc., a leading provider of containment systems for laboratory, pilot plant, and manufacturing has launched the Containment Process Builder (CPB), an online visualization and documentation tool that allows the user to build their very own containment process and visualize the combination of products in real-time. The purpose behind the Containment Process Builder is to provide a collaborative, interactive online builder that accelerates design, process, and equipment input during the concept stage of development.

  • Engineering controls designed to mitigate exposure and create separation between the operator and toxic material are available in many forms, all with their own unique advantages and risks.

  • This paper characterizes the new production directions in pharmacy and describes flexible equipment to improve pharma efficiency, purity, and production safety in the coming decade.

  • There are two basic models of pharma manufacturing: batch and continuous. And, generally speaking, many manufacturing procedures are transitioning from the batch to the continuous approach.

  • Here we will analyze and explain the different methods, their reasons, and which would be most beneficial for your first (or next) containment device to ensure personnel protection.

  • In analytical environments, precise weighing takes place inside containment where powders do not escape. The purpose of this paper is to measure the effectiveness of three vibration isolation strategies.

  • Flow Sciences is known for their flexibility and their unique reception of customer needs. When approached by a client with a specific design request, Flow Sciences was able to work with the client, including supplying a fiberboard mockup so they could make additional considerations before finalizing the design, to come up with a solution.

  • A two-part enclosure consisting of a single pass air flow glove box enclosure and a nitrogen purge enclosure was designed to provide protection to the operator and product.

  • Finding a solution to provide personnel protection when working with Highly Potent Active Pharmaceutical Ingredients (HPAPI) is very tricky. This case study describes a situation where a containment solution was designed for a benchtop vacuum oven process. Learn more about Flow Sciences’ Discovery process and how it resulted in a containment solution.

  • The Oncology Workstation with EziDock CSV6 HPAPI Transfer was designed to provide personnel and product protection while working with powder substances. 

  • Flow Sciences, Inc. was tasked with designing a modular containment unit that would house a Genevac EZ2 Elite Evaporator and allow for transfer of materials post-manipulation into a separate, connected balance enclosure for weighing. Read how they were able to deliver the product within the client's very specific size and performance specification.

  • The API Process Development System was designed to provide personnel and product protection when working with powder and liquid substances. 

  • A manufacturer required a glovebox that would enclose milling processes done by either a Fitzmill L1A or a Quadro Comil. Read how the design features allowed the operator the access and flexibility that they needed while achieving the containment requirements that were required.

  • A client required the design and build an enclosure that could house the Buchi B-290 Mini-Spray Dryer during process. The solution offered containment down to less than one microgram per cubic meter.

  • The potency and effectiveness of the ADCs are dependent upon engineered nanoparticles (ENPs), but little is known about the environmental and human health hazards posed by ENPs.

  • Originally designed around 350 years ago to contain accidents and prevent bad odors in the laboratory, the fume hood has become a device that can routinely produce control levels of vapors down to the part-per-billion level. In this study, Flow Sciences chose to meld existing techniques centered around ASHRAE 110 with widely-accepted particulate containment measurement techniques. The Flow Sciences fume hood, when used in conjunction with good lab practices, is capable of providing workers with the protection they need for applications using solids, liquids and gases.

  • Many existing research labs, pharmaceutical and biopharmaceutical manufacturers, and contract manufacturing organizations (CMO’s) are not designed nor are they equipped with the engineering controls to safely handle the manufacture of ADC’s. The safe manufacture of ADC’s requires more modern facilities, equipment, and engineering controls as well as programs, practices, and procedures to adequately protect the operators and the work environment. Read the steps that must be taken to consider a glovebox workstation fully validated to manufacture ADCs safely.

  • This paper discusses the primary benefits of the vented balance enclosure, which is critical to the safe and effective weighing of potent powder compounds, APIs, and nanomaterials. 

  • Containment enclosure solution for an analytical weighing and solution-preparation operation involving HPAPI in powder form allows manufacturer to successfully transfer product from an enclosure to another enclosure.

  • Though delivering, unloading, staging, and assembling are required steps in all lab construction, there are design aspects of lab equipment that can contribute to its successful field installation.

  • Understand what information you should be communicating to the manufacturer to ensure you get the best lab containment equipment, built correctly the first time.

  • Frequently, companies have used fume hood exhaust to ventilate hood base cabinets. There is both the need for this practice and the designs for them are frequently not well thought-out. 

  • Engineering is a process to develop a design to solve a problem. In the world of containment engineering, careful premeditation is important to the completion of a successful engineering project.

  • This paper reviews why very bad things happen when either quantity or purity of Highly Potent Active Pharmaceuticals is not properly maintained during the compounding process. 

  • Stability of your weighing balance is paramount when it comes to collecting reliable data. Depending on the problem, taking obvious action for a seemingly obvious solution may not result in success.

  • While there are “bad” fume hoods, anything wrong with the entire system (exhaust fan, ductwork, building configuration, regulative dampers) may cause a lack of containment in a hood.
