There are three 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, Hum
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.
Aerogard – 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.
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.
The flexible fit and wide variety of tip styles in the ZAP Premier range provides excellent compatibility with all popular pipette brands including:
Sartorius (Biohit) SafetySpace
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
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
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.
