Bio-Rad TLS0851 8-Tube PCR Strip 0.2 mL — 120 pcs / pack

Bio-Rad · 0.2 mL 8-Strip · Low-Bind Polypropylene · Flat / Domed Cap · 120 pcs

The Bio-Rad TLS0851 is a 0.2 mL, 8-strip PCR tube, low-bind (low-white) medical-grade polypropylene, with individually-attached flat / domed optical caps, supplied 120 pieces per pack. TLS0851 is part of the Bio-Rad life-science consumables family used in PCR, qPCR, RT-PCR and Sanger / next-generation sequencing workflows on the Bio-Rad C1000, S1000, T100, CFX96 and CFX384 thermal cycler platforms.

KOEED is best known as a multi-brand Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic and KEYENCE industrial-automation distributor, but the same RFQ pipeline also handles adjacent-category consumables — the Bio-Rad TLS0851 PCR tube strip is one of them. Biotech, clinical-lab, R&D and academic teams that already trust KOEED for thermal cyclers, robotic handlers, KEYENCE vision cells, and Siemens process-control hardware can add the consumable to the same BOM and ship it on the same invoice.

Key Technical Specifications & Overview

The TLS0851 strip is designed for high-efficiency thermal transfer and low analyte adsorption. Eight individually-attached 0.2 mL tubes on a single rigid frame sit in a standard 96-well SBS block pitch, so a full 12-strip row loads into any Bio-Rad 96-well cycler without adapters. Tubes are made from thin-wall medical-grade polypropylene, the cap is the same flat / domed optical-grade profile used in the higher-priced qPCR strips, and the low-bind (low white) surface treatment minimises DNA, RNA and protein adsorption to the wall. If you need a vendor datasheet or a lot-trace document for QA release, send a request to Moritta@KOEED.COM and KOEED will attach it to the quote.

Application Scenarios — Where It Fits

The TLS0851 is a general-purpose 0.2 mL strip, so it drops into almost any 96-well, 0.2 mL-block thermal cycler. KOEED typically ships the part into the following adjacent-category use cases — many of which also overlap with the same customers who source Allen-Bradley ControlLogix PLCs, Siemens SIMATIC S7 controllers, KEYENCE vision systems and Fanuc robotic handlers from KOEED.

• Molecular-biology and genomics labs — standard PCR, RT-PCR, multiplex PCR, SNP genotyping, low-volume qPCR where the low-bind surface preserves yield.
• Clinical diagnostics and hospital labs — pathogen detection panels (viral / bacterial load), HLA typing, pharmacogenomics, where validated Bio-Rad consumables are often a regulatory requirement.
• Forensics and DNA-analysis labs — STR profiling, low-copy-number DNA work, contamination-controlled sample prep, paired with Siemens or Omron lab-automation conveyors.
• Pharma R&D and biotech QC — cell-line authentication, mycoplasma screening, transgene detection, run alongside Mitsubishi MELSEC-controlled bioreactor skids.
• Food, water and environmental testing — pathogen screening in dairy, meat and water, GMO detection in grain, paired with Schneider Modicon process-control skids.
• Academic and university core facilities — shared CFX96 / CFX384 / T100 cyclers, multi-user labs, where the 120-strip pack size is the standard consumable unit.
• Industrial biotech and synthetic biology — strain engineering, library screening, NGS prep, often co-deployed with Yaskawa and Panasonic pick-and-place / liquid-handling cells.

Integration & Wiring Notes (PCR Instrument Compatibility)

The 0.2 mL, 96-well SBS pitch is the de-facto standard for mid- and high-throughput thermal cyclers, so the TLS0851 drops in directly without adapters, spacers, or clip modifications. The 8-strip frame indexes against the A1 corner of a 96-well block and the cap profile matches the Bio-Rad qPCR-seal geometry, so fluorescence reads through the cap remain linear across the standard FAM / VIC / ROX / CY5 dye set. Load the strips so the flat side of the cap faces the optical detection path; the domed side is mechanically equivalent but the optical focal distance is set for the flat face.

Verified compatible instruments include the Bio-Rad C1000 Touch, S1000, T100, MyCycler, MiniOpticon, Opticon 2, Chromo4, CFX96, CFX96 Touch, CFX384 Touch, DNA Engine, PTC-100 and PTC-200 thermal cyclers. The strip also fits most generic 0.2 mL-block instruments — Applied Biosystems 2720 / Veriti / Proflex, Eppendorf Mastercycler / Pro, Thermo Fisher ProFlex / SimpliAmp, Analytik Jena FlexCycler, and most Esco / Bioer / Hangzhou Bioer blocks. For Bio-Rad CFX systems, pair the strip with the matching Bio-Rad optical seal or cap strip to keep the CFX calibration within spec; aftermarket flat caps from unverified suppliers are a common source of erratic Ct values and have to be re-validated against the Bio-Rad reference.

When the TLS0851 strip is being run on a CFX96 or CFX384 that is in turn integrated with a Allen-Bradley CompactLogix skid, a Siemens ET200SP remote-I/O panel, or a Omron NJ/NX machine controller, treat the cycler as a 24V / RS-485 / Modbus TCP node on the lab-automation network and isolate the consumable lot number as a tracked batch attribute in the PLC tag database. A common fault pattern on integrated lines is the cycler running a partial strip in a column the PLC is unaware of, so wire the plate-loader handshake into the PLC interlock before commissioning.

Installation & Commissioning Tips

• Pre-warm the block. Pre-warm the 96-well block to 4 °C (or the protocol's initial hold) before loading the strips. A cold block on a warm strip causes micro-condensation under the cap, which skews qPCR baselines by 0.3–0.8 Ct on the first few cycles.
• Cap orientation. Cap the strip in one motion — press the cap strip down flat across all eight tubes in a single sweep, not one tube at a time. A mis-seated cap on even one tube leaks at 95 °C and ruins the run.
• Working volume. Keep the reaction volume between 10 µL and 50 µL per tube. Below 10 µL, evaporation losses dominate; above 50 µL, the meniscus sits above the optical read window and Ct values drift upward.
• Pipette tip compatibility. Use filtered, low-retention tips for low-copy targets. Standard tips carry over 1–2 % of the master mix, which is enough to fail a single-copy assay.
• Seal inspection. After capping, run a fingernail across the cap line. Any tube that gives under the nail is under-seated and has to be re-capped before the run starts. This is the single most common cause of an evaporated column on a CFX96.
• Storage after opening. Once the 120-strip pack is opened, store the remainder in the original resealable pouch with the desiccant at room temperature, away from UV. The low-bind surface treatment is sensitive to prolonged UV exposure and to organic-solvent contamination — do not store strips next to a TBE / TAE buffer bath.
• Lot traceability. For clinical and regulated work, record the Bio-Rad lot number from the pouch label into the LIMS or the PLC tag database. KOEED quotes include the lot and expiry date on every shipment.

Procurement, Warranty & Lead Time

KOEED is a multi-brand industrial-automation and lab-consumable distributor, not an OEM subsidiary. The Bio-Rad TLS0851 is sourced through our China sourcing supply line and kept in stock for spot purchases and recurring bulk orders. Every shipment is sealed in the original Bio-Rad pouch, lot-traceable, and shipped with a basic visual QC report; for QA-release paperwork or a Certificate of Analysis, request the document at RFQ time and KOEED will add it to the quote.

Lead time is typically 3–7 business days for in-stock single-pack and small-quantity orders, and 2–4 weeks for full lab-build BOMs that bundle the TLS0851 strip batch with Allen-Bradley PLCs, Siemens SIMATIC, Mitsubishi MELSEC, Omron SYSMAC, Fanuc robotics, Schneider Modicon, Yaskawa Sigma-7, Panasonic FP PLCs, or KEYENCE vision systems in the same shipment. Worldwide shipping is via DHL, FedEx, UPS, or nominated freight forwarder; see the Shipping Policy page for cut-off times and export documents.

Pricing is RFQ-only on this part number — Bio-Rad consumables are quoted by the pack, by the case, and by the half-pallet. Send your full BOM (TLS0851 strip packs, sealing caps, qPCR master mix, paired cycler or PLC line items) to Moritta@KOEED.COM and KOEED will return availability, lead time, and a single line-item quote within 24 business hours. For new customers, opening an account is a one-email step: institution / company name, end-user country, and a short note on the application is enough. If you are not sure whether the TLS0851 is the right strip for your cycler, the KOEED AI Diagnostic Tool can take a photo of the nameplate and suggest a Bio-Rad cross-reference.
