Pickering Test Solutions brochure coverFor several years now, Pickering Laboratories has continued to expand our line of Product Testing Solutions to include new synthetic body fluids or environmental solutions. We offer a variety of formulations of artificial perspiration, sebum and saliva for testing fabrics, plastics, dental alloys, medical devices, wearables and other electronics and many different consumer products.

The challenges that Covid-19 pandemic presents for the pharmaceutical and health care industry are staggering, and they impact manufacturers of medical devices and personal protective equipment as well. This brings into focus the need for artificial bodily fluids that can be used for both ongoing testing and tackling the new developments introduced by the Coronavirus crisis.

With that in mind Pickering has introduced new artificial saliva with mucin made according to ASTM methods E2720-16 and E2721-16. The official ASTM methods E2720-16 and E2721-16 specify artificial saliva formulation for the evaluation of decontamination procedures for surfaces and materials contaminated with human pathogenic viruses. The formulation has a mineral composition and pH close to human saliva and contains Mucin to increase the viscosity and lubricating ability of the solution. This artificial saliva can also be used for dental, drug delivery or pharmaceutical studies.

Pickering Laboratories also offers Artificial Lung Fluid called Gamble’s solution, which is used to simulate different interstitial conditions deep in the lung. Several artificial lung fluid formulations are described in literature and we would be happy to discuss customers’ particular testing needs and help you choose the correct solution for your specific application. As established manufacturers of medical devices are now joined by companies newly entering the health care space, we are proud to do our part in ensuring that medical equipment, such as ventilators, get properly tested.

Pickering’s staff is dedicated to working hard to support our customers, new and returning. We are recommitting to our promise of providing quality reagents and solutions quickly to support essential businesses and supporting manufacturers.

Larger sized bottles are now available of our new Artificial Sebum, giving customers the choice to purchase as 25 grams or 200 grams per bottle.  The new 200g bottles, part number 1700-0702, will provide significant savings over purchasing large amounts of Artificial Sebum in the smaller bottles (part number 1700-0700).  This product is available off the shelf, as inventory permits.

Our AATCC Test Method 15 Artificial Perspiration is a very popular formulation, particularly as the stabilized version with two years shelf life.  We currently offer this stabilized formulation in our standard 200mL bottles (part number 1700-0015), and as a case of 4 x 950mL bottles with part number 1700-0541 for larger volume users. 

It is with much excitement that we now offer the ability to order stabilized AATCC Test Method 15 Artificial Perspiration in even larger volumes!  By purchasing one of our new 19.8L carboys, our customers can save significantly on their large volume purchases.  Carboys of AATCC Test Method 15 stabilized sweat, part number 1700-0555, are available now as a made-to-order product.

These carboys, which hold almost 20 liters in a single container, are available for any customer wishing to purchase stabilized artificial perspiration in bulk volumes.  Please contact support@pickeringlabs.com for more information on bulk volumes of your artificial perspiration formulation of choice.

Artificial Eccrine Perspiration, artificial perspiration, Consumer Electronics Show, David Mazawa, Product Testing Solutions, Uncategorized

CES 2016… wait, what?

That’s right, Rebecca and I attended The Consumer Electronics Show (CES) 2016 in Las Vegas, Nevada. This massive show takes over Las Vegas for a whole week. Many of our Product Testing Solutions customers were going to be exhibiting at the show, so we thought it would be a good opportunity to meet our current customers and see if we could interest other companies in our Product Testing Solutions as well. We saw many cool devices being displayed. Drones, virtual reality rigs, augmented reality goggles, fitness tracking gadgets, and smart fabrics were all well-represented.

We decided to focus on the wearable technology section of the show. Any device or material that is worn on the human body would benefit from design testing or quality control testing with our Product Testing Solutions. Wearable technology companies already use our artificial perspiration solutions to see how their electronics or materials will tolerate constant contact with the human body. We have received feedback from customers that testing with our artificial perspiration solution will give different results, when compared to testing with just water. After testing with our artificial perspiration solutions, our customers are confident that their device or material will be able to withstand the harsh environment of the human body.

We met lots of passionate people promoting their awesome products. Many of these people thought we bottled actual perspiration! By the end of the day, Rebecca and I had walked over 7 miles so it was certainly possible for us to collect our own perspiration… However, Pickering Laboratories does not collect actual perspiration. We manufacture artificial perspiration and other body fluids according to industry standard protocols and our own proprietary formula for eccrine perspiration. No humans are harmed in the making of these products.
