Quality Control Procedure

Stringent quality control is the key of the success of HTL’s products. Within many years of manufacturing manual liquid handling systems we have worked out the control procedures allowing us to ensure that only 100% reliable product reaches the end users. Thanks to the harsh durability tests and precise accuracy and precision verification performed on all of our products our equipment is renowned for its sturdiness and long lasting reproducibility.

The control of the quality of HTL manufactured equipment is performed at the following stages of the production process:

• Statistical control of incoming raw materials and metal components
• Statistical control of the injected parts including shaft durability test
• Individual control of the components during assembly
• Individual post production control.

After assembly every product manufactured at HTL is subject to strict individual control performed in accordance with EN ISO 8655 standards. Testing is performed by highly experienced staff in state of the art, fully computerized laboratory. Accuracy and precision tests are conducted with distilled water by gravimetric method under stabilized temperature. Standard quality control procedure involves the following tests:

• Evaluation of product aesthetics (colors, imprints, etc.)
• Pipetting smoothness and pipetting force tests
• Air tightness test
• Accuracy and precision verification.

The testing results automatically enter computer control system which independently qualifies if the certain pipette meets company standards. Only once all tests are passed the Quality Control Certificate stating the performance of the product is being printed.

Quality Control Certificate presents true accuracy and precision results obtained during the control procedure of the certain pipette. The certificate is included in pipette box.
