Precision Tool Design
4titude®’s highly skilled engineers have extensive knowledge and experience in the design and manufacture of precision tools for injection moulding of thin walled and other laboratory consumables to tight tolerances. The latest technology is used for tool making, resulting in precision components of outstanding quality.
Our injection moulding tools undergo regular inspection and maintenance schedules to ensure that all parts can be moulded consistently and to highest standards.
Cleanroom Injection Moulding
All of our consumables are produced in cleanroom injection moulding facilities to ensure that the products remain free from particle contaminations such as bacterial and eukaryotic cells, dust or pyrogens.
ISO Certified Manufacturing
4titude®’s manufacturing standards comply with
DIN EN ISO 9001.
Virgin, Medical Grade Polymers
4titude® uses medical grade and fully biocompatible polymer granulates in all our processes. As an additional measure of bio-safety, we only work with virgin materials and avoid the use of mould release agents or other additives which may have a detrimental effect on product purity.
QC Procedures
4titude® plastic consumables undergo a wide range of QC inspections during and after the production process. We perform visual, physical and biological tests to ensure both the absence of contaminants as well as the integrity of the products at all times.
Tests include:
100% Inspection
Using a proprietary electrical discharge detection method we test every plate for its well integrity. Due to the sensitivity of this test we can guarantee for the absence of pin holes and knit lines which could otherwise lead to loss of valuable samples during DNA amplification (PCR plates only).
PCR Performance Test
PCR plate samples undergo thermal cycling for leak testing under extreme temperature conditions. At the same time the plates are tested for sealing performance using heat seals, adhesive seals and cap strips.
Visual Inspection
All plate types are visually inspected for moulding defects, impurities and for batch to batch consistency. Using state-of-the-art measuring equipment we verify that all parts have been produced to our own published tolerances or to industry standard specifications where appropriate (e.g. according to SBS standards).
Biological Testing
We perform functional QC testing using quantitative PCR (qPCR) to ensure that all products are free from nucleases (DNases & RNases) as well as human genomic DNA. LAL-Assays are used to test raw materials and finished product for the presence of endotoxins.
