Manufacturers and research organizations spend considerable sums of money to ensure their cleanrooms adhere to critical cleanliness standards – disinfection procedures are optimized, quality controls are implemented and regular particle counts and microbial tests are performed to identify the smallest pockets of contamination. With many safeguards in place to limit contamination, including interlocking doors, pressure gradients, and air showers, the most common source of particles, whether viable or non-viable, stems from the cleanroom staff. The first line of defense in preventing human-borne particles from entering into a cleanroom is the gowning area.

tainless steel is a key material in cleanrooms and other controlled environments due to its resistance to corrosion and ability to be easily cleaned and sterilized. However, stainless steel must be properly cleaned and maintained to ensure its long-term durability and performance. 

In this post, we will discuss stainless steel cleaning methods and techniques, as well as some tips on effectively cleaning and maintaining stainless steel surfaces.

ULPA filtration vacuums are an indispensable tool when staring down challenging or potentially hazardous spills and messes in a laboratory or production environment. The most formidable of these messes typically include hazardous, poisonous, irritating, or nausea-inducing dust and powders that are fine enough to be aerosolized and distributed through the air as. To prevent aerosolized particle generation during cleanup and removal, specialized HEPA or ULPA vacuums are used to remove, capture, and contain these substances before safely disposing of them.

Fungi proliferate in dark, damp, and warm environments which also serve as ideal environments for opportunistic pests, mold, bacteria, and plant-based viruses. Agar-based techniques are highly susceptible to contamination. Fungal contamination is difficult to reverse and quickly spreads throughout the local environments.

For retrofit projects converting an existing lab space into a cleanroom or cGMP area, the conventional solutions each come with unique challenges. New facility builds are cost-prohibitive, carry lengthy timelines, and hinge on the acquisition of a suitable facility. Depending on area requirements, installing a modular cleanroom inside an existing room is a fast, economical alternative, but often creates unusable or inaccessible space. 

As humans are the primary source of contamination in cleanroom and lab environments, cleanroom-compliant hand washers, sinks and hand dryers play a critical role in reducing bioburden and viable particle counts within sterile spaces.

A desiccator, also referred to as a dry box or dry cabinet, is a humidity-controlled chamber that produces a dry, clean environment conducive to the storage of sensitive materials, samples, or components. 

A Lithium-Ion battery consists of a cathode, anode, current collectors, and a porous separator that prevents shorting of the anode and cathode. As the Li-ion cell discharges energy, there is a significant increase in both temperature and the pressure exerted by the reaction. These two factors have the potential to result in a runaway chemical reaction, and ultimately an explosion. Thus, calorimeters must measure both temperature and pressure changes that occur to identify anomalies and prevent dangerous situations.

Terra Universal is a manufacturer and supplier of various cleanroom pass-through chambers and pass-through transfer windows that readily support healthcare, hospitals, and surgical environments.
