The Puretest 8-tip magnetic extraction tip comb is a single-row disposable sleeve strip for flexible magnetic-bead DNA, RNA and protein purification. It lets laboratories process one row of eight wells at a time while protecting the magnetic rods from direct reagent contact.
The Puretest 8-tip magnetic extraction tip comb is a single-row disposable sleeve strip for flexible magnetic-bead DNA, RNA and protein purification. It lets laboratories process one row of eight wells at a time while protecting the magnetic rods from direct reagent contact.
Eight parallel sleeves are molded as one strip with a shared upper support. Each sleeve surrounds one magnetic rod while the lower closed end enters the corresponding process well. The strip format is practical for partial-row throughput and for systems designed around removable 8-tip combs.

The disposable sleeves isolate the permanent magnetic rods from samples and reagents. During a validated program, vertical movement supports bead collection, transfer, washing and release without moving the entire liquid phase between process positions.

Values and compatibility statements are nominal. Confirm the current Puretest drawing, sleeve dimensions, packaging and applicable quality documentation before instrument validation or a production order.
| Application | Why This Format Is Suitable |
|---|---|
| Low- to medium-throughput extraction | Processes a single row without committing to a full 96-tip frame. |
| DNA and RNA purification | Supports magnetic-bead binding, washing and release steps. |
| Protein and immunoprecipitation workflows | Moves magnetic particles between compatible reagent positions. |
| Assay development | Useful for instrument and chemistry optimization with smaller sample batches. |
| Clinical-research laboratory preparation | Supports validated sample-processing workflows when the selected cleanliness status is appropriate. |
The 8-tip strip is intended for compatible magnetic-rod extraction systems that accept an eight-sleeve row and a matching deep-well plate. KingFisher®-type, Tianlong-type and other instrument names should be treated as geometry references only; confirm the exact magnetic head, retaining feature and process plate.
Puretest laboratory consumables are molded from high-purity polypropylene selected for chemical resistance, low biomolecule binding and dependable dimensional consistency. Available cleanliness, sterile and packaging configurations must be matched to the quoted catalog number.
If your workflow requires a Certificate of Analysis, Certificate of Conformance, irradiation record, DNase/RNase status, pyrogen limit, human-DNA limit, dimensional report or batch traceability, state the requirement before ordering. Puretest will confirm which documents apply to the selected configuration rather than treating every supply option as identical.
Puretest supports evaluation samples, current technical drawings, bulk and individually protected packaging, sterile and non-sterile options, customer catalog numbers, private labels, barcodes and distributor carton programs. MOQ, inner-pack quantity, case quantity, lead time, carton dimensions and shipping method are confirmed with the final specification.
| Format | Structure | Best-Fit Workflow |
|---|---|---|
| 8-tip strip | One row of 8 disposable sleeves | Flexible row-by-row magnetic-bead processing |
| 96-tip plate format | 8 × 12 array of 96 disposable sleeves | Full-plate automated extraction and purification |
Tip-comb compatibility depends on the magnetic head, plate geometry, sleeve depth and instrument program. Request the current drawing and validate a physical sample before routine use.
No. It is a disposable strip of eight closed sleeves that covers one row of magnetic rods. It is used together with a compatible process plate.
No. Well pitch, bottom geometry, sleeve depth and magnetic-head travel must match. Request the current drawings and samples.
Sterile and non-sterile supply configurations can be discussed. Confirm the exact status and supporting documents on the quotation.
The normal configuration is single use to reduce contamination and performance risk.
Send the instrument model, magnetic-head format, current comb or plate reference, photos if available and required process volume.
