Across International’s wide range of bacterial culture tools, including petri dishes and inoculating loops, are well suited for all life science and mycology applications, giving researchers the tools for success. Microbiological, or microbial, cultures are an essential process for the multiplication and growth of microbial organisms. This method of bacterial culture is crucial in the fields of mycology, diagnostic testing, medical research, microbiology, and more.

BioFactory systems are compact, multi-layer, single-use cell culture systems designed for easy scale-up of cell culture applications such as production of vaccines, monoclonal antibodies, or pharmaceuticals. The BioFactory is a versatile and easy-to-use system for medium to large scale research, or commercial production with reduced contamination risk. The NEST BioFactory™ allows for the closed transfer of liquid, meaning it can directly transfer the culture medium, or cells, to a cell factory or a bioreactor through a connecting tube, in a sterile environment, thus greatly reducing the risk of exogenous pollution in the drug development and production process.

Across International carries a wide selection of Nest cell culture plates and dishes, flasks, Biofactories, cell scrapers, cell slides, and more.

Cell culture is the process of growing plant and animal cells under controlled conditions, outside of their natural environment. Micropropagation, tissue culture, and cell culture all refer to the same technique; a technique that is crucial in the fields of cellular and molecular biology, as it provides a platform for research into the biology, biochemistry, physiology, and metabolism of wild-type cells and diseased cells.

Browse our comprehensive selection of centrifuge and microcentrifuge tubes in a wide range of sizes. We offer centrifuge tubes in 15 and 50 ml as well as 250 and 500 ml sizes, and microcentrifuge tubes in sizes ranging from .6 ml to 5 ml. Centrifuge tubes are used to store and handle liquids during the centrifugation process. Samples are placed in a machine, and spun at high speeds around a fixed axis, this high rotational speed creates a centrifugal force causing the liquid sample to separate into its various components. This process is a crucial step in many industrial and clinical sectors from diagnostic testing to biomolecular research.  

Cryogenic Vials are ideal for the cryopreservation of cells and other samples. Across international provides a wide selection of self-standing cryogenic vials, color coded cap inserts, and accessories like cryogenic boxes. Browse our selection of racked and bulk cryogenic vials, with your choice of internal or external threads. We also offer cryogenic vails that are compatible with Brooks systems.

Cryogenic and Freezer boxes are essential for the centralized placement of cryogenic vials. Cryogenic boxes are typically made of cold-resistant fiberboard, or plastics, and are built with drainage holes to remove melted ice/ liquid nitrogen. Some cryogenic boxes also have vent holes to further reduce condensation. Across International is a premier supplier of cryogenic and freezer boxes suited for all applications where cold sample storage is critical. 

Browse our comprehensive selection of laboratory cuvettes including UV cuvettes, PS and PMMA cuvettes, and Fluorimetry cuvettes. Cuvettes are used to hold samples for spectroscopic measurement, where a beam of light is passed through the sample within the cuvette, to measure the absorbance, transmittance, fluorescence intensity, fluorescence polarization, or fluorescence lifetime of the sample.

Deep well plates are ideal for sample collection and long-term storage, they are also utilized in many applications like the cultivation of microorganisms, genomic DNA extraction, plasmid DNA extraction, nucleic acid extraction, and the purification of various samples. Across International offers both Square Well and Round Well plates, with V-bottom and U-bottom options. In addition to our wide selection of deep well plates, we also carry sealing matts and deep well plate accessories.

Across International provides a large selection of Erlenmeyer Flasks, in both PETG and PC bottle materials. Our Erlenmeyer flasks are ideal for cell culture, cell culture shaker applications, and much more. We offer flasks in varying sizes and with options for baffles, flat bases, vent caps, and seal caps. In addition to individual flasks and caps, we also offer a wide range of accessories including transfer cap systems for inverted transfer, bi-directional transfer, multifunctional transfer, and more.

Deep well plates and tip combs that are compatible with KingFisher Purification Systems. Browse our selection of tip combs and deep well plates designed to be used with KingFisher Purification Systems. We offer the best solution for KingFisher compatible plates, and tip combs, that are in-stock and ready to ship.

PCR tubes are small tubes designed for use in polymerase chain reactions (PCR). Across International has both clear and white 0.1/0.2 ml PCR tubes, which are ideal for general PCR and qPCR reactions. Our low-profile PCR tubes can reduce evaporation of the reaction solution thus increasing the real-time PCR fluorescent signal strength.
