ISO 13485 is a stand-alone document that is similar in subject to ISO 9001, but with a direct focus regarding the manufacture and design of medical devices. There are a few key differences between the two standards, though. ISO 9001 has requirements for continual improvement of a company’s QMS while ISO 13485 just requires the…Details
Meet the New pHoenix XL
Our most advanced dialysate meter to date,the pHoenix XL digital dialysate meter is a convenient, hand-held, syringe-style meter for quick and accurate measurement of conductivity, temperature and pH. All without the hassle of annual calibration.
Introducing Our New Combination Solution
We have combined two of your most valuable NIST-traceable standard solutions into one bottle: 14.0 mS/cm and 7.00 pH in one solution! Make your daily calibration in half the time so you can focus on what matters most: patient care.
In order to ensure the most accurate results and optimal patient safety, we recommend daily calibration (formerly referred to as ‘Level 1’) of your pHoenix XL Dialysate Meter. Keeping your meter in calibration is now easier than ever before, with Mesa’s new 14.0 mS/cm and 7.00 pH combined solution to minimize calibration times while providing the same accuracy.Details
When you use a Mesa Labs Standard Solution, you are guaranteed accurate, reliable solutions. We work hard to make sure we take uncertainty out of the equation so you can focus on what’s most important: patient care. To put back more time in your day, we are excited to offer a NEW NIST-traceable Combination Standard…Details
Effective July 31, 2016, Mesa Labs will be discontinuing the current pHoenix meter model. Mesa Labs will continue to accept RMAs for service and calibration for seven years (pending parts availability) from the date of this notice. In addition, Mesa Labs will continue to accept orders for the current pHoenix meter up until the date…Details

50 mS solution now available
Mesa’s new 50 mS Conductivity Standard Solution allows the user to verify accurate readings during final bicarbonate testing using a NIST traceable standard as a qualified data point of 50 mS during meter verification and calibration.
Dialysis is based on the diffusion and ultrafiltration of fluid across a semi-permeable membrane. As blood flows past one side of a semi-permeable membrane, dialysate flows by the other side. Fluid and smaller solutes and pass through the membrane, but larger substances (e.g. large proteins and red blood cells,) are blocked by the membrane, mimicking the filtering process that takes place in the kidneys.
Hemodialysis works by removing waste and water from circulating blood by filtering it outside the body through a dialyzer which contains a semi-permeable membrane. Blood and dialysate flow in opposite directions, contributing to the concentration gradient that allows the maximum amount of urea and creatinine to be removed from the blood.
Dialysis solutions contain similar levels of certain minerals (e.g. calcium, potassium) as healthy blood. The blood of dialysis patients contains higher levels of potassium and urea than the dialysate so constant replacement of the dialysate through the dialysis process maintains this imbalance ensures that undesired solutes are removed from the patient’s blood. For bicarbonate, the level is set slightly higher than healthy blood to encourage diffusion. Individual patient needs dictate the concentrations of the components of dialysate, typically prescribed by a nephrologist.
To ensure patient safety, Mesa offers several digital dialysate meters to help the nephrology technician verify that the dialysis machine is functioning properly. The pHoenix, HYDRA and NEO-STAT test various parameters utilizing Mesa’s easy to use syringe style concept which is small in size and offers a host of advantages including a large, digital display, one-touch calibration and an auto-off battery saving feature.
In addition to these syringe style digital dialysate meters, Mesa offers its 90XL technician meter which can be used to test and calibrate all types of delivery systems and water purification systems.
Mesa Labs maintains a sophisticated calibration lab for all of its instrument products, including its line of digital dialysate meters.
Mesa’s in-house calibration is far more extensive than the user calibration options available to our customers. Mesa’s dialysate meters, in general, have two sets of calibration coefficients. A set that is exposed to the customer/user and is used to make minor adjustments to the accuracy of the device and a set that is exposed, in general, only to Mesa’s in-house calibration software.
Also, Mesa’s Calibration lab has the N.I.S.T. traceable standards at the facility to calibrate the meters to. A typical user doesn’t have access to N.I.S.T. traceable standards.
Lastly, if there is an issue with the function of the meter, Mesa has the OEM parts to correctly service, repair and re-certify a customer’s meter. Should an instrument or meter need repair, it can only be accomplished at our factory.
