5.0 out of 5 stars Fit for purpose
As someone who uses pH solutions daily I thought I'd test these out.They come in a printed cardboard box. The bottles are LDPE with a screw top and the labelling is clearly printed (I liked the lemon and leaf icons on the 4 and 7 buffers but the fish on the pH 10 was a little confusing). The colour coding was as per normal industry standards although a little less vibrant than some I've seen.This three pack has the necessary solutions to do a two or three point calibration on a pH meter.The accuracy of these buffers was as stated in the tolerances and they work well with my pH meter.Because of the narrow neck of the bottles these buffers are going to be dispensed into beakers for use, usually 100ml at a time. If you reuse the buffer do you pour it back into the bottle and risk contamination or dispose of it? If you throw it away then at best you'll get 3 calibration checks from each bottle.In an industrial lab you would purchase buffer solutions in 5L bottles as this reduces the cost so these buffers would be best suited to small quantity and infrequent users such as home or micro brewers on maybe tropical fish tank testing where the user has a small pH meter.Verdict: Good product but expensive for frequent users.
5.0 out of 5 stars Well made and good quality
This was great quality, and the solution itself seems high quality. We had no issues with it whatsoever. Highly recommend.
4.0 out of 5 stars Worked for calibrating my pH meter, well-priced for 250ml of ready to use calibration fluid
These ready to use buffer solutions arrived in a perfectly sized & GIDIGI branded cardboard box, inside which you get the three 250ml sized bottles. Each bottle is properly sealed, dyed a specific colour and labelled to avoid any confusion and the label also has a useful table printed on it showing the accuracy of the liquid’s pH based on the temperature. Though to be honest even at 0c they’re still plenty accurate for my needs at 4.01, 7.12 and 10d.31 pH, but if the accuracy of the calibration is paramount then you can bring the liquid to 25c for the best results.I’ve got a generic cheap pH meter that was in dire need of a recalibration as I'd run out of the supplied buffer powders, so these couldn’t have popped up at a better time for me personally. I appreciate that they’re a ready to use solution and for a person with a single pH meter a 250ml bottle will last for a long time. The 250ml bottles should easily last for ten or more calibrations as you only need to use 15-25 ml at a time if you’re using a narrow container.The £25.14 asking price is reasonable when compared to the other pre-mixed liquid pH calibration solutions on Bolo. With that said though, it’s very expensive when compared to the powdered sachets bundles you can buy and mix with 250ml of distilled water. But assuming you’re fine with the price point this is a very convenient and easy to use calibration option for people with electronic pH meters. I can’t speak to the shelf stability of the liquids, but I've had no issues storing the solutions made from the sachets for months at a time, and as long as you keep them in the recommended environment they’ll be just fine.
5.0 out of 5 stars Essential tool for stable preservation
I enjoy making home made hot sauces but giving them a long, stable, unrefrigerated shelf life eluded me for some time, until I started testing each batch for its pH level and adding citric acid as needed. Too little and the dangerous bugs come back; too much and you've got yourself sour sauce, not hot.Cheap pH meters are easy to come by but they usually only include a few sachets of calibration powder, and even then you need to purchase extra distilled water and mix up batches yourself. Again, cheaper, but very inconvenient, and makes you less likely to do it regularly in the first place.No, at £26.99 these aren't cheap, but in terms of saved money from spoilage and in sheer convenience they are a huge boon to me. I can now regularly test the calibration of my two pH meters and give friends my sauces without worrying that in a few days my gift will go off.Very happy.
5.0 out of 5 stars Large, long lasting bottles
This is a review of the Gidigi brand pH Meter Calibration Buffer Solution Kit. Which was priced at £26.99 at the time of posting this review.I use a pH meter to test the water in my aquarium and garden pond. Keeping the meter calibrated is important to ensure the health of my fish.I like these Gidigi solution as I trust the brand. I like that the bottles have a scale on the label to show the effect of temperature on any pH reading which can show higher or lower depending on the temperature of the buffer solution.These are nice large 250ml bottles which will last a long time.
5.0 out of 5 stars just what it says
Great quality calibration solution set! The bottles are clearly labeled, sealed well, and the volumes are generous for multiple uses. Worked perfectly to get my pH meter reading accurately again—definitely a must-have for anyone regularly testing pH.

This review is for the pH Meter Calibration Buffer Solution Kit, Including pH 4.00, 7.00 and pH 10.01 Solution, pH Meter Probe Calibration Buffer Solution, pH Tester Accessories 250ml*3I recently ordered a pH meter, so I was pleased to find these ready-made calibration solutions available. The set includes pH 4.00, 7.00, and 10.01, each clearly colour-coded for easy identification, which is a really helpful touch. They work exactly as expected, making calibration straightforward and reliable. A decent volume and convenient kit for anyone using a pH tester.
5.0 out of 5 stars All good
Does exactly what it says on the... Bootle. Decent size bootles will last for a while without doubt. Everything clearly marked, easy to use. No quality concerns at all. Very good value for money.

Rezension: pH-Pufferlösungs-Set (pH 4,00 / 7,00 / 10,01)Ich habe das Set mit den drei Pufferlösungen ausführlich getestet und kann es für die meisten Anwendungen empfehlen.Genauigkeit der pH-Lösungen (Laborüberprüft):- pH 4,00: Exakt gemessen (Labormessgerät: 4,0)- pH 7,00: Exakt gemessen (Labormessgerät: 7,0)- pH 10,01: Geringe Abweichung (Labormessgerät: 10,2)Wichtiger Hinweis zur Messgenauigkeit:Messsonden können immer nur in einem begrenzten pH-Bereich exakte Werte liefern. Selbst hochpreisige Sonden im dreistelligen Euro-Bereich erreichen selten eine perfekte Genauigkeit über den gesamten pH-Bereich. Daher sollte man sich vor der Messung genau überlegen, in welchem pH-Bereich man arbeiten wird und die Sonde gezielt in diesem Bereich kalibrieren. Die hier beobachtete Abweichung bei pH 10,01 zeigt dies deutlich - die verwendete Laborsonde war auf den sauren bis neutralen Bereich optimiert.Ein weiterer Pluspunkt dieser Lösungen ist die Normierungs-Tabelle welche die Abweichungen der pH-Werte in den entsprechenden Temperaturbereichen abbildet.Praktische Handhabung:+ Gut erkennbare Farben (jede Lösung hat eine andere Färbung)+ Stabiler pH-Wert über längere Zeit (Achtung! Bitte niemals die Messsonden direkt in die Aufbewahrungsflaschen einführen zur Kalibrierung)- Die halbdurchsichtigen Plastikflaschen bieten keinen ausreichenden Lichtschutz. Dunkle Behälter wären besser und noch besser wäre Glas.Fehlende EC-Kalibrierlösung:Das Set wäre noch nützlicher, wenn eine Leitfähigkeits-Kalibrierlösung (z.B. 1413 µS/cm) enthalten wäre, um auch EC-Messgeräte überprüfen zu können.Fazit:Solides Pufferlösungs-Set für den Hausgebrauch und semiprofessionelle Anwendungen. Die Lösungen erfüllen ihren Zweck zuverlässig, wobei man die natürlichen Grenzen von pH-Messungen beachten sollte. Für optimale Ergebnisse immer im relevanten Messbereich kalibrieren.Empfehlung:Gut geeignet für:- Hobbygärtner- Aquarianer- Schullabore- Einsteiger in der WasseranalytikWeniger geeignet für:- Labore da ich hier wieder Batch-Nummern noch Chargennummern finden konnte und auch entsprechende DIN 19266 Produktionsvermerke konnte ich nicht finden.Die bessere Wahl für Labore ist und bleibt der Standard wie z.B von Merck, Hanna, Sigma-Aldrich.Die Lösungen sind qualitativ hochwertig, aber die Aufbewahrung könnte verbessert werden. Eine EC-Referenzlösung als Ergänzung wäre wünschenswert.
Präzise
Super Kalibrationslösungen, wurden am Apera PH60 getestet, funktioniert genau so gut wie die anderen Lösungen. Absolut keine Probleme, wenn auch die Verschlusspapiere etwas nervig abzubekommen sind, musste sie dann abschneiden anstatt abziehen.
Lösungen für schnelle und präzise pH Kalibrierung
Den pH-Wert von wässrigen Lösungen bestimmt man mit pH-Messgeräten bzw. pH-Metern. Die dafür benutzten pH-Elektroden treten dabei mit der zu messenden Probe direkt in Wechselwirkung. Das hat Einfluss auf ihre Eigenschaften im Laufe ihrer Lebenszeit. Sie können im Laufe der Zeit und durch verschiedene Umwelteinflüsse (z. B. Temperatur, Alterung, Verschmutzung) ihre Genauigkeit verlieren. Durch die Eichung mit Standardpufferlösungen kann sichergestellt werden, dass die Elektrode korrekte Werte liefert. Die Genauigkeit der pH-Messung steht und fällt also mit der Kalibrierung und Justierung. Daher ist eine regelmäßige Kalibrierung sinnvoll und notwendig.Pufferlösungen zur Kalibrierung stellt man durch genaues Abwiegen von geeigneten Puffersalzen und Lösen in einem bestimmten Volumen von reinem Wasser her. Das ist zeitintensiv, vergleichsweise mühsam und fehleranfällig. Einfacher, genauer und bequemer wird der Vorgang, wenn man vorgefertigte Pufferlösungen wie die von Gidigi benutzt, bei denen man vom Hersteller auch Hinweise zur Haltbarkeit erhält. Die unterschiedliche Farbe der Lösung hilft zusätzlich, Fehler zu vermeiden. Es ist wichtig, die Lösungen zur Kalibrierung nur einmal zu verwenden. Sie dürfen keinesfalls in die Vorratsflasche zurückgekippt werden. Kurz: Hier ergeben Genauigkeit und Einfachheit der Handhabung eine Win-Win Situation. Daher meine Empfehlung.

Perfektes Set für die Kalibrierung von pH-Messgeräten. Alle drei Standardwerte enthalten, gut beschriftet und ausreichend Menge. Unverzichtbar für präzise Messungen – tut, was es soll!
