411-0018-038 Last-O-More Tubing 3x5 mm per Meter by WatchGas

Regarding sampling tubes for gas detectors, many manufacturers promote clear tubing as a cost-effective solution for drawing air from confined spaces. While affordability may be a key selling point, it's essential to recognize the limitations of clear tubing in gas detection.

In the automotive industry, clear tubing is avoided for crucial systems like fuel and windshield fluids because it lacks the necessary inertness. The same principle applies to gas detection. Some argue that clear tubing offers two benefits: it allows visibility of fluid intake, and discoloration signals the need for replacement. However, once a fluid is drawn into the tube, contamination of the inner walls occurs, requiring immediate replacement. Best practices call for avoiding fluid intake altogether, which is why devices like ball floats are used—visible, such as the yellow one pictured.

Discoloration of clear tubing often points to a reaction between the sampled gases and the tubing material itself, proving the material's unsuitability rather than providing a reliable replacement indicator.

Inexpensive aquarium tubing made from PVC is commonly repurposed for gas detection, but PVC's inherent odour is a clear sign it's not suitable. While there are other, more promising materials—such as those with Teflon inner linings—these are no longer cheap, and Teflon can flake, causing blockages.

That's why we developed Last-O-More tubing, made from fluorinated elastomer (rubber). It's inert, doesn't flake, is highly flexible, and resists binding. Plus, it's explicitly marked as a gas sampling tube to ensure correct use.

While not the cheapest option, Last-O-More tubing has been rigorously tested in the lab using GC analysis. It has proven to be the best in absorption and retention—retention, meaning the release of absorbed gases when exposed to heat (like sunlight).

Last-O-More tubing is black, so always pair it with a ball float or water trap (filter) and replace it when it no longer feels slippery. Proper tubing is critical in gas detection—don't compromise safety.

AI2910 CalPod Solution Organizer by Apera

The Apera Instruments' unique CalPod helps users organize all the solutions in one place and create no more mess in the calibration process. The CalPod can hold up to 4 types of different solutions simultaneously. The hole in the center of the CalPod is for users to place the electrode. This CalPod is a great accessory for pH meters and all other kinds of meters that require regular calibration.

After calibration, close the lids so the solutions can be used multiple times.

Stickers for commonly used solutions for pH and conductivity testing are included. Blank stickers are provided for users to write special solutions' names.

• Say goodbye to all the mess during calibrations
• Simply organizing all calibration solutions into one place for multiple uses
• Label Stickers included in the kit
• Easy to rinse off

WB-7500-P Bottle, Plastic Wash Bottle 16oz / 500mL by AquaPhoenix

These bottles are made of translucent and low density polyethylene (LDPE). The distinguishing feature of these bottles is the built-in delivery tube which makes it a one-piece wash bottle. Graduated on the outer surface to reflect an approximate volume of solution filled or dispensed.

TDS15000/P Conductivity Solution, 15,000ppm/16,630uS, 1Pt by Sensorex

TDS/Conductivity instruments and sensors must be calibrated together. For a single-point calibration, select the one solution that approximates the expected conductivity or ppm level of total salts. Mixed Salt standards are the most frequently used in the field to sample naturally occurring water sources, boiler feed water, or cooling tower water. Typical river water, well water, or lake water sample will contain a mixture of several different salts. Sensorex Mixed Salt standards simulate a "Natural" mixture of common salt compounds found in these sources. Sodium sulfate, sodium bicarbonate, and sodium chloride salts are blended to provide a representative value. There are certain applications where Single Salt Solutions are preferred. NaCl Solution is routinely used to calibrate instruments measuring Sea Water or brackish water samples. Reagent grade salt and high resistivity DI water is compounded for accurate results. KCI Single Salt Solution may be used with conductivity meters that read directly in Siemens or Ohms. KCI (potassium chloride) is established as an international calibration standard for conductivity measurement. Choose the conductivity calibration solution that is right for your application.
