96-Tip Magnetic Extraction Tip Comb for Deep-Well Processing for Automated Magnetic-Bead Processing

The Puretest 96-tip magnetic extraction tip comb provides a full 8 × 12 array of disposable sleeves for parallel magnetic-bead purification. It protects the magnetic head while supporting repeatable bead collection, washing, transfer and release across an entire 96-well process plate.

A rigid upper frame holds 96 closed polypropylene sleeves on standard 8 × 12 centers. Each sleeve surrounds one rod of the magnetic head and enters the matching process well. Consistent sleeve depth and frame flatness are important because alignment errors can reduce bead recovery or create mechanical contact.

Product Highlights

• 96-sleeve 8 × 12 array: Supports full-plate high-throughput extraction and purification.
• High-purity polypropylene: Offers chemical resistance and low biomolecule binding.
• Uniform sleeve geometry: Supports consistent magnetic-rod clearance and bead movement across the plate.
• Deep-well processing format: Designed for matching deep-well magnets and compatible 96-well plates after validation.
• Protects the magnetic head: Prevents direct contact between permanent rods and samples or reagents.
• Single-use contamination control: Suitable for batch-based molecular workflows.
• Throughput-oriented frame: Loads as one comb instead of individual sleeve strips.
• OEM and documentation support: Samples, drawings, sterile options and private-label packaging can be discussed.

Tip Comb Structure and Functional Design

A rigid upper frame holds 96 closed polypropylene sleeves on standard 8 × 12 centers. Each sleeve surrounds one rod of the magnetic head and enters the matching process well. Consistent sleeve depth and frame flatness are important because alignment errors can reduce bead recovery or create mechanical contact.

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.

Technical Specifications

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 Guide

Workflow and Equipment Compatibility

This format is designed around full 96-position magnetic heads and matching process plates. Compatibility may include selected KingFisher Flex, Apex or Presto-type deep-well workflows, but the instrument model, magnetic-head variant, process plate and retaining mechanism must all be confirmed before use.

• Match the comb to the magnetic-head type and the exact plate geometry.
• Confirm sleeve-to-rod clearance, vertical travel, well-center alignment and deck height.
• Validate mixing speed, stroke, bead-release efficiency and residual carryover with the intended chemistry.
• Use the tip comb once unless the validated protocol and quoted configuration explicitly state otherwise.
• Do not use a damaged, warped or contaminated comb.

Material, Cleanliness and Quality Documentation

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.

Handling and Use

1. Inspect the packaging and comb for damage before loading.
2. Load the comb in the orientation specified by the instrument and confirm full mechanical engagement.
3. Use a compatible process plate and sufficient headspace for programmed mixing.
4. Run a low-risk validation protocol before processing valuable samples.
5. Dispose of the used comb according to the laboratory’s biological and chemical-waste procedures.

Packaging, Supply and OEM Support

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.

Choose the Right Magnetic Extraction Tip Comb

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.

Frequently Asked Questions

What is the difference between a 96-tip comb and an 8-tip strip?

The 96-tip comb processes a full plate in one frame. The 8-tip strip processes one row and is useful when batch size or instrument architecture requires a smaller format.

Does it fit every KingFisher® instrument?

No. Different instruments and magnetic heads use different combs. Match the current drawing and a sample to the exact system.

Which deep-well plate should I use?

Use the plate specified for the magnetic head and protocol. Check well pitch, capacity, bottom geometry, plate height and sleeve clearance.

Is a sterile version available?

Sterile and non-sterile configurations can be discussed. The quotation should state the applicable cleanliness and batch documentation.

Can Puretest supply the comb and plate as a set?

Yes. Provide the instrument model and preferred plate format so a matched evaluation set and commercial packing plan can be proposed.
