Give fragile and viscous samples more room to move.
An enlarged orifice helps reduce shear during aspiration and dispensing of cells, long DNA strands and difficult liquids. MTC Bio Ultra Low Force™ tips pair wide-bore geometry with low retention, sterile 96-position racks and a choice of filtered or non-filtered formats.

- Viscous sample aspiration and dispensing
- Transfer of gel fragments or large cells where protocol permits
Selection and Use Tip
Wide bore reduces flow restriction but does not guarantee cell viability, DNA integrity or pipetting accuracy for every liquid. Confirm your pipettor model, technique and sample-specific performance before substitution.
Frequently Asked Questions
Why choose a wide-bore tip?
The enlarged opening reduces flow restriction and helps reduce shear stress during aspiration and dispensing. MTC Bio identifies fragile cells, long DNA strands, viscous solutions and particulates as suitable applications to evaluate.
Which pipettes do these tips fit?
MTC Bio specifies compatibility with Rainin LTS and MTC SofTouch low-force pipettors. The 200 µL tips are specified for 50, 100 and 200 µL LTS pipettes, and the 1000 µL tips for 1000 µL LTS pipettes. Verify your exact pipettor model; these are not universal-fit tips.
Which catalog numbers are filtered?
P4615-200WBF and P4615-1000WBF are filtered. P4615-200WB and P4615-1000WB are non-filtered. Choose the format required by your method.
Are all four configurations sterile and low-retention?
Yes. The manufacturer lists all four configurations as sterile and low-retention. Each pack contains 10 racks of 96 tips. Maintain suitable handling after opening the packaging.
Can I compare the 200 µL filtered version with Rainin 30389241?
MTC P4615-200WBF and Rainin 30389241 are both 200 µL, sterile, filtered, low-retention, wide-orifice options for LTS pipettes supplied as 10 racks of 96. Rainin publishes a 1.5 mm orifice for its product; that diameter is not established here for MTC. These are different manufacturers’ products, not OEM or certified equivalent tips. Validate sealing, accuracy and sample recovery.
Does wide bore guarantee intact DNA or viable cells?
No. Sample integrity depends on pipetting speed, mixing, liquid properties and the complete procedure. Optimize technique and validate viability or fragment integrity in your assay.
Are these Rainin-manufactured tips?
No. They are MTC Bio products with manufacturer-stated LTS compatibility. Rainin LTS is a registered trademark of Mettler-Toledo Rainin, LLC; Blue Tiger Scientific is not affiliated with that manufacturer.
What does one unit ordered contain?
One pack of 960 tips: 10 racks of 96 in the selected volume and filter configuration. Pricing and inventory are per 960-tip pack, not per rack or tip.
