200µl pipette tips, yellow, racked

These 200 µl universal, bevelled, yellow, non-sterile tips in a rack from Alpha Laboratories are ideal for accurate pipetting of small sample volumes. The tips are 50 mm in length and are not graduated. They have been manufactured from high-quality, non-cytotoxic, radiation-stabilised, virgin medical-grade polypropylene. The resin is pre-tested to determine if extractable substances are present that will interfere with PCR or DNA. Resins with a high level of extractables in the 240 nm to 320 nm range are excluded from production. These tips offer versatility as they are compatible with a range of major pipette brands. The wide sealing area ensures a secure fit with the pipette, whilst the bevelled end retains less fluid and is a good choice for a variety of procedures. Each lot of tips is tested and certified RNase, DNase, DNA and endotoxin/pyrogen free. If the product is labelled as sterile, sterilisation is by gamma irradiation. The sterilisation process follows ISO 11137 procedures for sterility. The tips can also be autoclaved at 122 °C for 20 minutes at 15 psi. The 200 µl universal, bevelled, in a rack, yellow, non-sterile tips are supplied in 10 x 96 racks.
