If your lab runs Rainin LiteTouch™ (LTS) pipettors, the way you stock your tips can make a bigger difference than you might expect. LIGHT LABS carries the complete Sorenson BioScience LTS Low Retention pipette tip line — every volume, every format — so you can choose the right tip for every application without switching suppliers.
Whether you're doing routine liquid transfers, running PCR and qPCR setups, working with precious samples where every microliter matters, or fielding a high-throughput plate-filling workflow, there's a Sorenson LTS Low Retention tip built for it.
Why Sorenson LTS Low Retention Tips?
The LiteTouch System was designed to reduce hand and wrist strain by requiring less insertion and ejection force than universal tips. Sorenson LTS tips are precision-engineered to match the LTS geometry, delivering the same ergonomic advantage that LTS pipettor users already expect — plus a meaningful upgrade: Sorenson Low Retention surface treatment.
Standard polypropylene tips retain a thin film of liquid on the inner walls. At larger volumes, that loss is often negligible. At 20 µL or 200 µL, especially when working with viscous samples, expensive reagents, or concentrated nucleic acids, that residual volume adds up. The Sorenson "T" series — identified by the "T" suffix in the catalog number — treats the tip interior to minimize sample adhesion, so more of what you pipette actually gets where it needs to go.
Key advantages of the full Sorenson LTS Low Retention line:
- LTS-Optimized Fit — engineered for Rainin LiteTouch™ single- and multi-channel pipettors; not a universal tip
- Low Retention Surface — reduces sample left on the tip wall for better recovery across all volumes
- Certified Clean — RNase/DNase-free, human DNA-free, PCR inhibitor-free, and non-pyrogenic
- Graduation Marks — quick visual accuracy checks during dispensing
- Three Formats — Reload Stack, TipStation, and MultiRack Barrier to match your workflow
The Smart Pairing: Reload Tips + Barrier Tips
Many labs using LTS pipettors buy barrier (filter) tips for PCR, qPCR, NGS library prep, and other contamination-sensitive applications. That's exactly what the Sorenson MultiRack Barrier tips are built for. But not every pipetting step in your lab requires a barrier — and running barrier tips for routine transfers adds cost without benefit.
Here's the practical solution: the Sorenson Reload tips drop directly into your existing empty barrier tip racks. No transfer device needed — each clear reload deck loads straight into an empty rack of the same footprint. That means when you finish a rack of barrier tips, you don't need to buy a new rack of standard tips. You just reload it with Sorenson's non-sterile, low retention reload tips for your everyday liquid handling work.
This two-product system lets you get full use out of every rack you buy: sterile barrier tips for sensitive applications, reload tips for everything else — all in the same physical racks, all with the same LTS fit and low retention surface.
Three Formats for Every Workflow
Reload Stack — Most Economical Per Tip
Reload decks are the lowest-cost-per-tip way to buy LTS tips. Each deck holds 96 tips and drops into an empty standard LTS rack without any special equipment. Available in 20 µL, 200 µL, and 1000 µL, non-sterile, and sold by the case. Ideal for high-volume routine work where sterility isn't required — and a perfect complement to your barrier tip racks once they're empty.
TipStation (Double Stack) — High-Density Plate Work
TipStation tips come in a compact double-deck format that fits LTS TipStation holders, giving your 8- and 12-channel pipettors a high-density tip source that doesn't tip over mid-run. Each deck holds 192 tips (double the standard), and cases contain 4,800 tips total. Available in 20 µL and 200 µL, sterile. The right choice for multichannel workflows where you need more tips per footprint.
MultiRack Barrier — Sterile Filter Tips for Sensitive Work
Barrier tips with built-in aerosol filters to protect your LTS pipettor and prevent cross-contamination between samples. The MultiRack format uses pre-loaded racks with hinged lids, sterile. Available in 20 µL, 200 µL, and 1000 µL, sold by the pack. Designed for PCR, qPCR, NGS library prep, RNA work, and any application where carryover or aerosol contamination is a concern — and their empty racks are ready for reload tip refills when the barriers are used up.
Applications
- PCR and qPCR Setup — low retention ensures full master mix transfer; barrier variants prevent aerosol carryover
- RNA and Protein Work — low retention surface critical for high-value low-volume samples
- DNA Quantification — precise 20 µL transfers with graduation marks for visual checks
- NGS Library Prep — sterile barrier tips at each step where cross-contamination is unacceptable
- High-Throughput Plate Filling — TipStation format for multichannel pipettors; reload format for economical refill
- General Liquid Handling — everyday LTS-fit transfers where low retention makes a measurable difference

Need an LTS Pipettor Too?
If your lab is adding LTS-compatible pipetting capacity — whether you're replacing an aging pipettor, adding a second single-channel, or moving to a multi-channel — LIGHT LABS also carries the SofTouch ULF LTS-compatible pipettors. The SofTouch ULF line is engineered for the same low-force LTS tip engagement, making it a natural pairing with the Sorenson tip line for labs that want ergonomic pipetting from tip to pipettor.
