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.

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.

Water purification systems remove a wide variety of contaminants from feed water (tap water or pre-treated water) to produce pure water ideal for a host of applications within the lab.

Laboratory shakers rotate in an orbital, or reciprocating, motion to ensure thorough mixing of liquid samples and reagents.

PCR thermal cyclers optimize sample conditions to empower the amplification of target nucleic acid sequences for quantitative and qualitative analysis. Thermal cyclers are designed to perform two types of polymerase chain reaction (PCR) methods: end-point, or standard PCR, and real-time qPCR.

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.

Vortexers, or vortex mixers, 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 controls, vortex timers, and alarms.

Laboratory homogenizers 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.

Microplates, or microtiter plates, are designed to hold microliter aliquots of samples for analytical research and clinical diagnostic testing. 

Laboratory circulators and chillers precisely control the temperature of deionized water, bath fluid, or PH-neutral buffer for delivery to integrated or external water baths, analytical instruments, incubators, and wet processing stations.
