MTC Bio specifies medical-grade polypropylene designed for low retention.
Sterile, ready-racked
Presterilized tips come in 96-position racks, protected in plastic wrap.
Optional filter
Filtered versions use a modified polyethylene filter to help block aerosols and contaminants from the pipettor shaft.

Purpose-Built for Low-Force Pipetting
The SofTouch ULF collar and stopping point are designed to provide a consistent seal while reducing attachment and ejection force. MTC Bio specifies fit on SofTouch ULF and Rainin LTS pipettors. The listed instrument volumes are supplier-reported compatibility groupings, not validated working-volume ranges; confirm your model before ordering.
Typical Applications
- Routine reagent and buffer transfer with compatible low-force pipettes
- PCR and molecular-biology workflows where the specified cleanliness meets the method
- Small-volume sample preparation and dispensing
- Aerosol-sensitive handling with the filtered configuration
Confirm material compatibility and your method’s requirements before use. No additional performance or regulatory certification is implied.
Practical Bench Tip
Match both the pipette family and tip capacity. Follow the pipettor manufacturer’s seating and ejection instructions and your lab’s contamination-control procedures.

Frequently Asked Questions
Are SofTouch ULF tips an alternative to Rainin LTS tips?
MTC Bio specifies its SofTouch ULF tips for Rainin LTS pipettors, so they may be an alternative when the tip size and your model are compatible. P4615-20F and Rainin 30389225 are both 20 µL maximum, sterile, filtered tips supplied as 10 racks of 96 for LTS-family pipettors. Rack design, sterilization details and certifications may differ; validate fit and performance before changing products. Trademarks belong to their respective owners; comparison does not imply endorsement, affiliation or common manufacturing origin.
Can P4615-20F replace Rainin 30389225?
Both are 20 µL maximum, sterile filtered tips in 10 racks of 96, specified for LTS-family 2, 10 and 20 µL pipettes. They come from different manufacturers; rack and certification details may differ. Confirm your specific model and validate pipetting performance before substitution. Rainin LTS is a trademark of Mettler-Toledo Rainin, LLC; no affiliation or endorsement is implied.
Which catalog numbers are filtered?
P4615-20F, P4615-200F, P4615-300F and P4615-1000F are filtered. The corresponding R SKUs are non-filtered.
What pipette capacities match each tip?
MTC Bio lists 20 µL tips for compatible 2, 10 and 20 µL pipettes; 200 µL tips for 50, 100 and 200 µL; 300 µL tips for 200, 250 and 300 µL; and 1,000 µL tips for 1,000 µL instruments. Confirm model fit.
How many tips are in each pack?
P4615-20F/20R, 200F/200R and 300F/300R contain 10 racks of 96, or 960 tips. P4615-1000F and 1000R contain 6 racks of 96, or 576 tips.
Are these tips sterile and low-retention?
Yes. MTC Bio describes the racked tips as sterile and manufactured for low-retention performance. It also states that they are certified free of endotoxins, pyrogens, RNase, DNase and PCR inhibitors.
What do the filters do?
The modified polyethylene filters in F SKUs help block aerosols and contaminants from entering the pipettor shaft. They do not replace validated contamination controls.
Are these universal-fit pipette tips?
Do not assume universal fit. MTC Bio specifies SofTouch ULF and Rainin LTS compatibility. Confirm your exact pipettor and volume before ordering.
