Filter Tips

Alpha Laboratories has an extensive range of pipette tips for both routine and specialist applications. As part of an ongoing development programme, we continually improve our range to meet customer demands.

There are five aerosol resistant filter tip ranges available from Alpha Labs to keep your pipettes and samples free of contamination.

All are produced from the highest quality virgin polypropylene and are certified for the absence of DNase, RNase, DNA, Pyrogens, ATP and trace metals. They offer a comprehensive choice of tip styles and volumes to suit almost any pipette.

ZAP Premier™

These racked tips provide ultimate protection from both aerosols and fluid contamination. They incorporate a robotically-inserted, patented filter, made from high molecular weight polyethylene. The pores in this filter are very small (~10µm) and can trap even radionucleotides, preventing them from reaching the pipette barrel.

Another benefit is that in the event of over-pipetting, the filter blocks the fluid ingress so that it is not absorbed, preventing sample loss and possible pipette damage. The filter tips are sterilised by gamma radiation but can be autoclaved to re-sterilise as required. The volume range is 0.1-1250µl.

The flexible fit and wide variety of tip styles in the ZAP Premier range provides excellent compatibility with all popular pipette brands including:

  • Gilson

  • Biohit

  • Eppendorf

  • Rainin*

  • Brand

  • Thermo


Now you can reduce your plastic usage when you need a quality aerosol resistant filter tip for your exacting applications.

FastZAP™ refills can be used to refill empty pipette tip racks with ZAP™ filter tips. Their low carbon footprint makes them an ideal solution to waste reduction goals for your lab. They bring the ease and value of Fastrak refills to your filter tips.


These racked & loose filter tips offers effective aerosol protection and are available in a diverse range of tip styles including low retention, gel-loading and large volume options. They are sterilised by either e-beam or gamma radiation and are not recommended for autoclaving. The volume range is 0.1µl-10ml.

The choice of filter tips encompasses the following:

  • Standard filter tips for PCR and other applications in the volume range 0.1-1,250µl

  • Wide bore “Cell Saver” Tips in the volume range 20-1000µl

  • Low retention tips for protein work in the volume range 0.5-1,000µl

  • Gel-loading tips for electrophoresis in the volume range 0.5-100µl

  • Large volume tips in the volume range 5-10ml

Sartorius (Biohit) SafetySpace™

Sartorius filter tips are manufactured to perfectly match Sartorius (Biohit) pipettes. As a result, you have the assurance of an excellent fit and seal, giving the best possible performance.

These tips have been designed to leave a larger than normal air space between the sample and the filter. This avoids the problem of the sample coming into contact with the filter and is particularly useful in the following applications which require an extra volume in the tip:

  • Pipetting foaming liquids such as buffers and proteins

  • Pipetting solvents

  • Multiple dispensing functions of electronic pipettes

  • Reverse pipetting


An excellent choice for laboratories looking for quality and affordability, whilst being kind to our environment. They are designed for consistent sample dispensing with the highest accuracy and precision. The tips have a universal fit with enhanced cone geometry that ensures compatibility with a wide range of popular brand pipette models.

Designed for consistent sample dispensing with the highest accuracy and precision:

  • Available sterile and non-sterile

  • Packaged loose or racked

  • Standard or extended length

  • Volumes – 10μl, 200μl, 1000μl and 1250μl

  • Universal fit with a wide variety of popular pipettes

Paradigm™ Low Retention

Created to improve pipetting accuracy while also increasing throughput. Considerably more hydrophobic than standard tips, Paradigm tips enable even viscous fluids to be dispensed more completely.

Paradigm filtered pipette tips offer an extra level of confidence and control by providing a barrier between the nose cone of the pipettor and the sample.

The Paradigm filter membrane:

  • Composed of high-density polyethylene (HDPE)

  • Contains no additives that can contaminate samples if encountered

  • Provides a barrier against contamination, but will not impede airflow

  • Hydrophobic properties prevent absorption of samples

Premium Surface Tips

Nerbe Plus premium surface low retention pipette tips are optimised for the highest precision and reproducibility in a pipetting cycle. These filter tips contain sophisticated filter material with optimum pore density perfect the tips.

  • Compact

  • Autoclavable

  • Stable

  • Stackable

  • 100% Recyclable
