20 µL universal pipette tips for controlled low-volume transfer, supplied in filtered and non-filtered configurations. Request the exact sterility, pack format and cleanliness documentation required for your workflow.
Puretest 20 µL universal pipette tips support low-volume liquid handling in PCR setup, reagent preparation, dilution and microplate workflows. Filtered and non-filtered versions are consolidated on this page to help purchasing teams compare the two functional configurations without mixing them with other tip capacities.
The tapered 20 µL geometry provides a fine distal profile for microtubes, PCR vessels and small wells. A defined proximal sealing zone is designed for engagement with compatible pipette cones, while the clear tip wall makes it easier to observe the liquid column during method setup. Filtered variants incorporate an internal aerosol barrier above the liquid path; non-filtered variants retain an unobstructed air path for routine work.
| Configuration | Typical selection reason | What to confirm |
|---|---|---|
| Filtered | Contamination-sensitive PCR/qPCR, DNA/RNA workflows and sample handling where aerosol transfer is a concern | Barrier type, sterile status and any required cleanliness certificate |
| Non-filtered | General reagent transfer, mixing, dilution and routine sample preparation | Pack format, sterile/non-sterile status and pipette fit |
| Nominal maximum capacity | 20 µL |
|---|---|
| Tip configurations | Filtered or non-filtered |
| Material | Polypropylene; resin grade and supporting statement confirmed by SKU |
| Colour | Natural / clear unless otherwise quoted |
| Packaging | Rack, refill or bulk subject to order specification |
| Sterility | Sterile and non-sterile options subject to SKU |
| Cleanliness claims | Only those explicitly stated for the quoted SKU and supported by product or lot documentation |
| Compatibility | Broad-fit design; sample testing required on the exact pipette model |
| Variant | Filter | Sterility | Typical pack choices* |
|---|---|---|---|
| 20 µL universal tip | No | Non-sterile or sterile by SKU | Bulk, refill or rack |
| 20 µL universal filter tip | Yes | Non-sterile or sterile by SKU | Rack; other formats by quotation |
*Pack count and rack configuration must be confirmed in the quotation.
It is the nominal maximum capacity used to identify this tip family. The usable pipetting range is determined by the pipette, tip fit, liquid properties and validated method.
Yes. They share the same nominal capacity but serve different contamination-control needs, so the ordering table distinguishes them clearly.
No universal assumption should be made. Sterile and non-sterile supply depends on the exact SKU. Request sterility and related documentation in the RFQ.
Provide the pipette brand, model, channel count and cone type. Sample testing should check attachment, seal, ejection and volume performance before routine use.
“Universal” indicates a broad-fit design and does not guarantee fit with every pipette. These tips are independent compatible consumables, not products of any pipette manufacturer. Buyers must validate fit and performance for their equipment and application.
Send your pipette model, filtered/non-filtered requirement, sterile status, packaging preference and annual demand. Puretest will quote the appropriate 20 µL configuration and arrange samples for fit evaluation.
