Product Specification of Interlab’s Johnson Test Papers
The easy-to-use Johnson Test Papers pH indicator strips and papers are suitable for the Laboratory, Healthcare, Food and beverage, Education, Environmental, Safety, Cosmetics, Home Brew, Industrial and Water Treatment. Johnson Test Papers are manufactured using high-quality papers which are impregnated with mixed indicator solutions and then dried to be cut to size afterwards. The benefits of Johnson Test Papers are their intense colour development, non-bleeding, precise results, they deliver rapid results, consistency and their calibration and quality assurance by NIST certified pH buffer solutions. The Shelf Life of pH products is 2 to 3 years from the date of manufacture. Each pack is packed with the expiry date and batch number for that specific product code.
Interlab supplies both 0-1000ppm Chlorine Indicator Strips, 164.1C and 0-500ppm Peracetic Acid Indicator Strips, 168.5C. These are conveniently packaged and protected from external moisture, light and ambient gases to prolong their shelf life, which is up to three years if stored correctly.
The 0-1000ppm Chlorine Indicator Strips, 164.1C measure the concentration of free chlorine in sanitising / disinfecting solutions. Water reservoirs, water mains suppliers and swimming pools globally still utilise chlorine-based products for disinfection or sanitisation. Electroplaters also utilise chlorine to detoxify cyanide-containing waste. Regulations by New Zealand government and local health authorities dictate the use of chlorine test strips to ensure the correct concentration of sanitiser solutions are being used as specified within the foodservice industry. The colour chart has matches at 0-50-100-250-500-800-1000 ppm. Each kit contains 100 test strips in a handy Hydrion vial and matching colour chart. Each kit provides for 100 tests.
The 0-500ppm Peracetic Acid Indicator Strips, 168.5C. These strips allow the quick and easy detection of peracetic acid to determine the correct levels for sanitising for the fruit and vegetable collection process and also for determining any residual levels after sanitising, therefore, aiding in preventing potential contamination. The colour chart has matches at 0ppm, 100ppm, 250ppm, and 500ppm. Each kit contains 100 test strips in a handy Hydrion vial and a matching colour chart. Each kit provides 100 tests.
Interlab also Supplies Johnson Test Papers Non-Bleed Strips
This system makes the colour change remain far longer and readable until the pad is dry. Strips with the non-bleed system provide precise pH values as the different colours do not mix at the point of testing. Each Strip is long enough to protect the user from the test solution as the test pads are at the extreme end of the strip. For accurate pH Readings, these strips use up to 4 different indicator pads and the colours on the enclosed colour chart match the colour and position of each pad on the strip. This allows these strips to provide a rapid method of measuring the pH of a solution while producing high-quality results each time.
The 0-14 Universal pH Indicator Strips, 140.4 feature 3 pads allowing for precise and accurate measurement. This Indicator Strip is Interlab’s most popular as it encompasses the entire pH scale from 0-14.
