Non-flammable glass wool for use in general laboratory and industrial applications. Used for filtering out fine precipitates where filter papers are not suitable and the intertwined borosilicate glass fibers provide thermal insulation. (1 per EA )

Protect against cross-contamination using these racked, sterile filter pipette tips. These universal tips are manufactured from polypropylene and the filters are manufactured from polyethylene with a hydrophobic design to prevent liquids and aerosols from entering the body of the micropipette. These tips are non-cytotoxic, non-hemolytic, and have 99.9% Bacterial Aerosol Filtration Efficiency (BFE). DNase, RNase and Pyrogen free. Packaged in racks of 96 with 10 racks in each. (960 per PK )

Spunlace non-woven wipes are constructed from a hydro-entangled, nonwoven blend of 55% cellulose and 45% polyester. This composite substrate has the highly absorbent properties of a natural fiber with the cleanliness and strength of a synthetic yarn. Recommended for use in cleanroom Class 10,000+ (ISO 7+) critical environments such as research labs, hospitals, and electronics manufacturers. (1 per EA )

United Scientific® Coated Wire Rack, 15 mL Centrifuge Tubes, 15 Place, Blue (1 per EA )

UniStore™ polyethylene terephthalate glycol (PETG) bottles are designed for long-term storage of media, biological buffers, and various reagents. Bottles are leakproof (tested to 95 kPa), durable, as well as freezer-safe, making them ideal for storage and transport. Includes a high-density polyethylene (HDPE) closure with heat-shrink band for a tamper evident seal. Bottles feature raised graduations for easy readability. (48 per PK )
