Puretest 200 µL Rainin LTS-compatible pipette tips are designed for routine laboratory liquid handling on selected LTS-style pipette shafts. The consolidated page combines filtered and non-filtered configurations while keeping sterility, low-retention and packaging choices explicit for procurement and validation.
Puretest 200 µL Rainin LTS-compatible pipette tips are designed for routine laboratory liquid handling on selected LTS-style pipette shafts. The consolidated page combines filtered and non-filtered configurations while keeping sterility, low-retention and packaging choices explicit for procurement and validation.
This consolidated page replaces separate filtered and non-filtered listings. Buyers can compare both configurations under one capacity, reducing duplicate pages while making the ordering decision clearer.
The upper tip section uses an LTS-style cylindrical interface with a limited sealing area. This geometry is intended to reduce the force needed to load and eject tips compared with a conventional tapered friction fit. A positive stop helps limit over-insertion and supports more consistent seating across channels.
The polypropylene shaft tapers toward a fine dispensing orifice. Filtered configurations add an aerosol barrier above the liquid path; non-filtered configurations retain the full unfiltered air path. The filter is not a liquid reservoir and the operating method should prevent the sample from contacting it.
| Selection | Recommended Use | Ordering and Validation Note |
|---|---|---|
| Filtered | PCR/qPCR setup, NGS library preparation, RNA work, clinical or forensic samples and workflows where aerosol carryover must be controlled | Confirm sterility, filter material, cleanliness documents and usable volume for the quoted SKU |
| Non-filtered | Routine buffers, reagent dispensing, general sample preparation and workflows with established contamination controls | Available sterile or non-sterile subject to configuration; confirm surface and packaging |
A filter reduces the available internal air path and changes fluidic behavior. Recheck accuracy, precision, immersion depth, aspiration speed and blow-out when changing between filtered and non-filtered tips.
| Nominal capacity | 200 µL |
|---|---|
| Recommended volume context | routine low- to mid-volume methods up to 200 µL; validate every critical transfer point |
| Tip interface | LTS-style cylindrical low-force sealing geometry; compatibility must be qualified |
| Tip material | High-purity virgin polypropylene; exact resin and color by SKU |
| Filter | Filtered or non-filtered |
| Retention surface | Standard or low-retention option, subject to SKU confirmation |
| Sterility | Sterile or non-sterile, configuration-dependent |
| Rack format | 96 tips per rack; commonly 10 racks per case configuration, subject to Puretest confirmation |
| Pipette context | Selected Rainin manual and electronic single- or multichannel pipettes equipped with LTS shafts |
| Use | Single-use laboratory liquid handling |
| Documentation | Material, cleanliness, sterility and lot documents confirmed for the quoted catalog number |
Nominal capacity and platform context do not constitute a universal performance guarantee. Confirm the current Puretest drawing and validate the exact tip, pipette, liquid and method before routine or regulated use.
These tips are intended as independently manufactured alternatives for selected Rainin pipettes fitted with LTS-style shafts. Compatibility depends on the exact pipette model, channel count, shaft condition, calibration, tip geometry and liquid-handling method. They are not universal tapered tips.
The 200 µL family is a general-purpose choice for microplates, reaction tubes and reagent preparation. Filtered and non-filtered tips can require different liquid-class or manual-pipetting technique, particularly near the method limits.
| Application | Recommended Configuration | Why |
|---|---|---|
| PCR, qPCR and nucleic-acid workflows | Filtered, sterile; molecular-biology documentation confirmed | Helps control aerosol carryover and protect the pipette |
| 96-well plate setup | Filtered or non-filtered by assay risk | Racked format supports multichannel row loading |
| ELISA and immunoassay preparation | Non-filtered or filtered according to carryover risk | Suitable for routine reagent and sample transfers |
| Protein and detergent solutions | Low-retention option where available | Helps reduce residual film and reagent loss |
| General buffer dispensing | Non-filtered | Practical choice for controlled routine workflows |
Puretest LTS-compatible tips are molded from high-purity virgin polypropylene for laboratory liquid handling. Material color, standard or low-retention surface, filter, sterility and packaging are configuration-specific and must be linked to the quoted SKU.
For molecular-biology workflows, state the required DNase, RNase, human-DNA, PCR-inhibitor, endotoxin or pyrogen limits before ordering. Puretest will confirm which declarations, Certificates of Analysis, Certificates of Conformance, irradiation records and lot-traceability documents apply to the selected configuration. A claim from one option must not be transferred to every tip in the family.
The tips are single-use consumables. Do not wash and reuse tips for analytical work because wetting, cleaning and chemical exposure can alter surface behavior, retention and contamination risk.
The standard presentation is a 96-position rack. Filtered and non-filtered supply, sterile and non-sterile configurations, refill systems, low-retention options and alternative case quantities can be discussed by exact capacity. Puretest also supports evaluation samples, customer catalog numbers, private labels, barcodes, carton artwork and distributor programs.
MOQ, rack color, tips per rack, racks per case, inner packaging, sterilization method, shelf life and lead time are confirmed on the final quotation. Do not place a validated order from a family description alone.
| Capacity | Typical Workflow | Product Page |
|---|---|---|
| 20 µL | Micro-volume PCR, qPCR, NGS and reagent setup | View 20 µL options |
| 200 µL | Routine molecular biology, plate work and general liquid handling | Current selection |
| 1000 µL | Large-volume sample preparation, buffers and mixing | View 1000 µL options |
Choose capacity first, then specify filter, sterility, retention surface and packaging. The three capacities are not interchangeable.
Capacity and fit are the same family; the filter is an ordering option. Combining them makes comparison easier and removes duplicate SEO pages.
Rainin literature sometimes names the unfiltered geometry as 250 µL while listing 200 µL maximum application capacity. This Puretest page is organized by the 200 µL customer workflow; confirm the exact drawing and quoted SKU.
The 96-position format is intended to support compatible multichannel loading, but every channel must be checked for seating, seal and ejection.
No. Standard and low-retention surfaces are separate configurations and must be specified.
Yes. Provide the pipette model, channel count and target liquids so the relevant filter and surface options can be selected.
Send the pipette model, channel count, target volumes, liquids, filtered or non-filtered preference, sterility and cleanliness requirements, annual quantity and destination country. Contact Puretest for a compatibility sample, current drawing, documentation confirmation or commercial quotation.
