Our Pastette 40th Anniversary Winners – Harefield Hospital

Kelly Devine and her colleagues from the Immunosuppression Monitoring Laboratory at Harefield Hospital were the lucky winners of a Tassimo Coffee Machine in our Golden Ticket Giveaway for the 40th Anniversary of Pastette®.

Here’s what they had to say about Alpha Laboratories’ Pastettes:

“We have been using plastic transfer pipettes for over 20 years to decant our extracted blood samples for drug analysis by mass spectrometry.

We also use them for removing plasma/serum from our spun samples.

We expect high quality pipettes and started ordering Pastette from Alpha Laboratories three years ago when the company we were using let us down.

We have not looked back; Alpha customer service is excellent – ordering is quick and easy, they always deliver on time and the prices are very competitive.”

Pastette® Product Change Notification

Subject: Resin Source Change for Alpha Laboratories’ Pastettes®


At Alpha Laboratories we continually strive to optimise and improve our products to provide our customers with the best possible solutions. Periodically this involves a review of raw materials and their sourcing, to ensure continuity of supply. As a result, please be advised that we will be utilising a newly sourced Low Density Polyethylene resin for the manufacture of our Pastettes.

This new LDPE resin is a similar grade to that currently used and complies with the same regulatory requirements. A comprehensive verification has been completed to confirm all products meet our current specifications. This change will ensure our Pastettes continue to be manufactured to our high quality standards.

We expect to implement the change of low density polyethylene resin during the second quarter of 2018. Stringent source management will be implemented to maintain tight control and traceability. All other materials used in the manufacture of the products will remain the same; therefore, this change is not expected to affect the form, fit or function of our finished products.

The following supporting documents are available through these links:

If you require additional information in relation to this notification, please contact us. Thank you for your continued support of Alpha Laboratories’ Pastettes.

CE IVD Labelling of Pastettes (Pasteur or Plastic Pipette)

Can Pastettes (Pasteur or Plastic Pipette) carry the CE IVD label?

hand-pastette-4Directive 98/79/EC on In Vitro Diagnostic Medical Devices (IVDD) provides the regulatory framework for manufacturers and for authorised representatives who wish to place in vitro diagnostic (IVD) products on the EU common market.  Products that satisfy the regulatory requirements are permitted to carry the CE IVD mark.

Products for general laboratory use are not in vitro diagnostic medical devices unless such products, in view of their characteristics, are specifically intended by their manufacturer to be used for in vitro diagnostic examination.

For a number of years, there has been confusion on whether products such as pipettes  could carry the CE IVD mark.

In 2012 the European Commission Directorate General for Health and Consumers issued guidelines on certain products to clarify the position on CE IVD marking.

Further guidelines were issued in 2014.

In both these sets of guidelines it is very clear that pipettes, are not permitted to carry the CE IVD mark as they are for general laboratory use only and are not specifically intended to be used for in vitro diagnostic examination.

Hence all such pipettes under the Alpha Laboratories brand of Pastettes will not be CE IVD marked once current stocks are depleted.

The products will still be available and manufactured to the same high standards – they will just not carry the CE IVD mark.

If you require further clarification please contact us.

Graduated Pastettes Provide Accuracy and Convenience For Robertet UK Ltd

“The 1ml Graduated Pastette (Pasteur or plastic pipette) provides the precision needed”.  “We use a lot of Pastettes on a daily basis”  “Graduated Pastettes provide accuracy and convenience.”

The Robertet Group is a specialist company whose principal activities are the production and distribution of raw materials, flavours and fragrances.

Tony Jukes, Manufacturing Operations Manager, told us:

“In the applications laboratory here, we formulate trial batches of fragrances that are under development, for customers to test in their required applications. We work to very precise formulations, occasionally using up to 70 different raw materials for each trial batch. These components are often very expensive with some raw materials costing up to £20,000 per Kg. We cannot afford to waste any, so the accuracy of dispensing is essential. We have found that the 1ml graduated Pastette provides the precision that we need for this task.

Bristol Royal Infirmary (Extended Fine Tip Mini Pastettes)

Pastettes_in_Clinical_BiochemistryExtended Fine Tip Mini Pastettes used by Bristol Royal Infirmary.

The Department of Clinical Biochemistry at Bristol Royal Infirmary is a busy clinical laboratory processing around 1800 samples each day.

Samples arrive both directly from the hospital and from local GP surgeries. The  laboratory offers a full range of blood tests and most of these are processed through automated systems.

Some are still handled manually because they are either too complex to automate, or there is insufficient sample throughput to make it cost effective to automate.

Around 40 paediatric samples are received daily from the hospitals wards and outpatient services.
