Puretest 1250 µL universal pipette tips provide additional nominal capacity beyond the standard 1000 µL class for compatible pipettes and methods. Filtered and non-filtered configurations are presented together, while the 1250 µL family remains separate from 1000 µL products to avoid capacity and image confusion.
The 1250 µL tip body provides additional internal capacity while maintaining a tapered outlet for controlled dispensing. Its sealing region is intended for compatible extended-capacity pipette cones; it should not be assumed interchangeable with every 1000 µL tip or pipette. The filtered option adds an aerosol barrier above the liquid path, while the non-filtered option provides a direct air path for routine transfers.
| Configuration | Typical use | What must be confirmed |
|---|---|---|
| Filtered | Extended-capacity transfers where aerosol movement toward the pipette is a concern | Barrier, usable volume, sterile status and cleanliness documentation |
| Non-filtered | Routine buffer, media, reagent and sample transfer | Pipette fit, tip length, pack format and sterile/non-sterile status |
| Nominal maximum capacity | 1250 µL (1.25 mL) |
|---|---|
| Configurations | Filtered or non-filtered |
| Material | Polypropylene; exact grade and declarations confirmed by SKU |
| Colour | Natural / clear unless otherwise quoted |
| Length | SKU-specific; request drawing or dimensional confirmation where vessel reach is critical |
| Packaging | Bulk, refill or rack subject to SKU |
| Sterility | Sterile and non-sterile options subject to SKU |
| Cleanliness claims | Only those expressly listed for the quoted SKU and supported by documentation |
| Compatibility | Extended-capacity broad-fit format; sample validation required |
| Variant | Filter | Supply options* | Required buyer data |
|---|---|---|---|
| 1250 µL universal tip | No | Bulk, refill or rack | Pipette model, tip-length need, sterility, pack and quantity |
| 1250 µL universal filter tip | Yes | Rack; other formats by quotation | Pipette model, barrier, sterility and certificate needs |
*Availability, dimensions and pack count must be confirmed in the quotation.
Do not assume interchangeability. Fit depends on cone geometry, and the usable volume depends on the pipette. Request samples and validate the exact combination.
It is the nominal maximum capacity of this family. The validated working range is determined by the pipette, tip fit, liquid and method.
They may be available by SKU. State both requirements in the RFQ and obtain supporting product documentation before use.
Include your pipette model and vessel-reach requirement in the enquiry so dimensional information or evaluation samples can be matched to the proposed SKU.
Puretest universal tips are independent compatible consumables, not original equipment manufacturer products. “Universal” describes intended broad fit only. Final fit, seal, ejection, usable volume and method performance must be validated by the buyer.
Send the 1250 µL pipette model, filter choice, sterile status, required tip length, packaging preference, annual demand and documentation requirements. Puretest will prepare a fit-evaluation sample and quotation.
