We use ALS for both TVC & endotoxin. TVCs tests are relatively inexpensive (I forget the exact figure) and are significantly less than the endotoxin test. Results come by email after 7 days. There are drop off point / collection options (depending on where you are) for multiple samples or small quantities go by Royal Mail -though the Special Delivery service required to get the samples to the lab in the required time frame costs rather more than the TVC test!
Make sure you get the Atmis software installed - great for checking your results and they can also set and upper limits you want so you can immediately see if you have any failures without having to trawl through all the figures.
