Top Quality for Best Performance
Throughout the development of the Alpha Laboratories Pastette range, quality has remained a priority.
Users experienced with using glass Pasteur pipettes know that the drop size of a pipette is proportional to the external circumference of the tip. It is therefore essential that the cross section of the tip is perfectly circular. Oval cross sections will result in uneven drop sizes.
Quality manufacturing is therefore essential.
Testament to the quality of the Pastette manufacturing process is the development of a standard pipette with a very fine tip. The first fine tip pipette produced (LW4060) proved to be very popular in laboratories across Europe and Alpha Laboratories now produces a wide range of fine tip pipettes to support a variety of applications.
When it comes to transfer pipettes, choose Pastette, the name that delivers quality for all your application needs.
ISO-9001 registered manufacture of single use transfer pipettes ensures top performance for the clinical, diagnostic, life science, industrial, pharmaceutical and research markets.
The Pastette brand is renowned for giving customers both confidence and value.
Pastette products are widely recognised for quality, safety, consistency and craftsmanship.
Their single piece construction and responsive finger control gives performance that can be relied upon time and time again.
Remember when you reach for Pastette, you’re reaching for the best.
Pastette® and a competitor product were tested and compared. FTIR (Fourier transform infrared spectroscopy) was performed on 1ml and 3ml graduated pipettes. Using pipettes that had not been previously handled or used, a small portion was cut from the bulb of two pipettes from each brand and design. One piece was washed with Ethyl alcohol, dried with a wipe and labelled as “clean”. The other piece was left as found and labelled as “original”. The scan from the “clean” pipette was subtracted from the “original” samples for each type to show any differences or extra peaks. A noticeable residue was found on some of the competitor transfer pipettes. This residue was extracted and analysed via FTIR and found to be Oleamide/Erucamide which is a commonly used release agent in moulding. These compounds are of potential concern as they are a source of interference in some biological assays (e.g. G protein-coupled fatty acid receptor assays). No residual Oleamide was found via FTIR on Pastette brand transfer pipettes.
Following comparative testing on some competitor transfer pipettes they contained higher levels of bioactive extractible compounds that may interfere with biological assays. No residue was found on the Pastette brand transfer pipettes: You can rely on the Pastette® brand.
