Product Description
Reach deeper and recover more sample with the Sorenson BioScience 77300T 300 µL XT Barrier Pipette Tips. These are sterile, extended-length, low retention filter tips, racked in Sorenson's MultiRack system. The "T" low retention version minimizes sample loss with viscous, detergent-containing, and protein-rich solutions, so more of your sample is delivered with each dispense.
At 77 mm long, the XT tip is about 27 mm longer than a conventional 200 µL or 300 µL tip (50 mm). That extra reach gets into deep-well plates, tall tubes, and narrow vessels while keeping the pipettor shaft clear of the sample. An inert barrier guards your pipettor against aerosols and carryover contamination, and it won't trap liquid or contaminate the sample if you over-pipette. Every tip is certified RNase/DNase-free, human DNA-free, PCR inhibitor-free, and non-pyrogenic, so it's ready for sensitive molecular and cell-based work.
Each pack contains 768 tips (8 racks of 96). The low retention 77300T is available exclusively through LIGHT LABS, your trusted source for Sorenson BioScience pipette tips and liquid handling supplies.
KEY FEATURES
- Low retention (T) – LIGHT LABS exclusive low-binding polypropylene minimizes sample loss for more accurate, complete dispensing
- Extended length (XT) – 77 mm tip reaches deep-well plates, tall tubes, and narrow vessels
- Inert barrier filter – Protects pipettors from aerosols and cross-contamination without trapping liquid or contaminating samples when over-pipetted
- Certified contaminant-free – RNase/DNase-free, human DNA-free, PCR inhibitor-free, and non-pyrogenic
- Sterile – Ready for PCR, cell culture, and other contamination-sensitive work
- 1 to 300 µL range – Fits universal 100 µL, 200 µL, and 300 µL pipettors
- Graduated – Reference marks at 10, 50, 100, and 200 µL for quick visual volume checks
- MultiRack system – 96-tip racks with standard 9 mm spacing for single-channel and multichannel pipettors
- Clear polypropylene – Lets you see the sample during aspiration and dispensing
- Pack of 768 tips – 8 racks of 96 tips per pack

WHY CHOOSE EXTENDED LENGTH TIPS?
Standard 200/300 µL Tip: About 50 mm long, for routine pipetting in standard tubes and 96-well plates
XT Extended Tip: 77 mm long, reaches the bottom of deep-well plates, tall tubes, and narrow vessels without touching the pipettor shaft to the sample
WHY CHOOSE LOW RETENTION?
Standard Tips: Fine for aqueous buffers and routine solutions
Low Retention (T) Tips: Recommended for proteins, enzymes, detergents, glycerol-based solutions, and precious or low-concentration samples where every microliter counts
APPLICATIONS
- PCR and qPCR setup
- Deep-well plate pipetting and nucleic acid extraction
- Protein, enzyme, and detergent-containing solutions
- Cell culture and sterile sample handling
- Sample transfer from tall tubes and narrow vessels
- Molecular biology, genomics, and clinical research labs
