In accordance with the ISO 14644 standards, ISO Class 7 cleanrooms represent a highly controlled environment that is engineered to maintain specific cleanliness values. The enclosed system encompasses ceiling-mounted fan filter units (FFUs) that generate a continuous supply of HEPA or ULPA-filtered air. In this article, we'll cover top-level considerations and standards for ISO 7 cleanroom design and construction. Additionally, we'll explore general principles for ISO 7 standards including particulate levels, ACH requirements, and equipment-based considerations among several unique application ..read more

mix, blend or pulverize chemical and biological samples to form a uniform, homogenous suspension for further analysis. More specifically, homogenizers are used to lyse cellular structures, mill environmental samples, emulsify immiscible materials, and disperse chemical compounds by particle size ..read more

, gently agitate liquid samples by creating a vortex motion within the sample tube. Vortexers are composed of a drive shaft, oriented vertically, and connected to an electric motor, encased in a plastic or steel housing. The top end of the drive shaft protrudes from the housing and attaches to a micro-tube cup adapter or rack designed to accommodate microplates or multiple test tubes. Simple vortexers turn on automatically when a micro-tube, containing the sample, is pressed into the rubber cup. Advanced vortexers include analog or digital controllers with on/off switches, mixing speed control ..read more

Terra Universal manufactures a vast selection of stainless steel products for cleanrooms, hospitals, laboratories, and other controlled environments. Among these steel-constructed products, you'll find tables, workstations, glove boxes, pass-throughs, doors, and more ..read more

Cleanroom selection is a critical decision for a company. The wrong design choice may result in procedural inefficiency, cross contamination, or certification failure. Let’s discuss common questions Terra customers have when specifying and purchasing a cleanroom ..read more

 are a class of automated instruments used to dispense, transfer, dilute, or mix samples and reagents. Liquid handlers accurately handle small sample volumes, ranging from microliters to milliliters, and perform a variety of operations, including pipetting, mixing, and serial dilution. Automated liquid handlers offer several benefits when compared with manual experimental prep ..read more
