AEROSOL FILTER TIPS prevent pipettor contamination and sample carry-over. Recommended for sensitive PCR work where contamination can be detrimental to assay results. In addition to pipetting DNA or RNA solutions, filter tips are also recommended for pipetting hazardous solutions containing infectious agents or radioactive substances like P32. Our robotically inserted polyethylene filters have 10 µm tortuous path channels to block aerosols and contaminants without absorbing an overdrawn sample. They are fully autoclavable and lot-tested for extractables, endotoxins and nucleases to ensure accurate delivery of untainted samples. They are not self-sealing, which ensures complete sample recovery should there be contact with the aerosol filter.

Autoclavable
Thomas pipet tips are precision molded from medical grade virgin polypropylene and are designed to fit securely onto many popular pipettors. All are certified to be free of RNase, DNase and endotoxins and can be autoclaved at 122°C for 15 minutes at 15 psi.
DESCRIPTION
Hinged Racks
Hinged racks allow convenient single-handed access to upright tips that are arranged in 8 x 12 or 8 x 24 (192) formats for standard size tips (1-200 µL) This format is particularly useful when working with multiwell plates and multichannel pipettors.
These also come in a 10 x 10 (100) format for larger tips (100-1000 L). The wide plate hinge and positive snap lock prevent accidental opening if dropped. Rugged enough to be refilled and reused.
All size configurations are available either sterile or non-sterile. They can be user-autoclaved if the lids are left open.
Bulk Bags
These bags are zip-seal resealable containing 1,000 tips. Bulk bags are economical and produce the least amount of packaging waste. Not available sterile.
Individually Wrapped
These tips come in sterile peel-apart packets. 200 per box or 2,000 per case. Ideal for infrequent usage or where guaranteed sterility is imperative.
Sterility
Thomas sterile tips have been certified sterile using a validated medical process. We follow ISO 08-3009 procedures for sterility. Sterile products are clearly labeled and bioburden studies have been completed and are on file.
High Volume/Special Packaging Options
We offer options for laboratories that have special needs for high volume liquid handling or recycling-waste reduction programs. Automation capable, heavier duty robot-racks or permanent pipet tip reloading systems to cut waste by 90% are available. Please call for more detailed information.
A tip with quality you can depend on
A validated ISO 9001 quality-assurance system ensures repeatable and dependable performance. Every medical-grade resin lot is tested for extractables before use so it will not interfere with PCR or DNA work. Additional tests for fit, function and reproducibility are conducted on each lot against the listed pipettors. The validated sterility process keeps all bioburden studies on file.
THE FOLLOWING TIPS ARE ALL DISCONTINUED. QUANTITIES ARE LIMITED.
