pH 4.01 Calibration Solution by Hanna Instruments 25 Pack 20ml Sachets

Description

Product Overview

The Hanna Instruments pH 4.01 Calibration Solution is a high‑purity electrolyte designed to provide a stable reference point for pH meters used in a wide variety of laboratory environments. Each sachet contains 20 ml of solution that has been carefully formulated to match the pH 4.01 standard, a critical point in the calibration curve for most glass electrode sensors. The product is supplied in a case of 25 individually sealed sachets, allowing users to maintain a fresh supply for daily calibration routines, field work, or quality‑control checks. The solution is manufactured under strict quality‑assurance protocols, ensuring consistency from batch to batch and compliance with international laboratory standards. With a compact packaging size of 6.3 × 6.8 × 3.4 inches and a lightweight design of 1.45 pounds per case, the product is easy to store, transport, and integrate into existing laboratory workflows.

Usage

This calibration solution is ideal for routine verification of pH meters in research laboratories, educational institutions, pharmaceutical quality‑control labs, environmental testing facilities, and industrial process monitoring stations. Users simply dissolve the sachet contents in a clean container, allowing the solution to reach ambient temperature before immersing the electrode. The stable pH 4.01 value provides a reliable midpoint reference that, when combined with a pH 7.00 buffer, enables accurate two‑point calibration of most modern pH meters. The solution is also suitable for field calibration of portable meters, where the sealed sachets protect the reagent from contamination and evaporation. Because the formulation is resistant to microbial growth, it can be stored for extended periods without loss of accuracy, making it a cost‑effective choice for laboratories that require frequent calibration.

FAQ

What is the recommended storage condition for the calibration solution?

Store the sachets in a cool, dry place away from direct sunlight. Keep the container tightly sealed to maintain solution stability and prevent moisture ingress.

Can the solution be used with both benchtop and portable pH meters?

Yes, the pH 4.01 Calibration Solution is compatible with a wide range of glass‑electrode pH meters, including laboratory‑grade benchtop instruments and handheld field devices.

How often should I calibrate my pH meter using this solution?

Calibration frequency depends on the instrument’s usage and the criticality of measurements. For most laboratory applications, daily calibration is recommended, while field instruments may be calibrated before each measurement session.

Is the solution safe to handle, and are there any special disposal requirements?

The solution is non‑hazardous under normal laboratory conditions. Dispose of empty sachets according to local waste‑management regulations; they can typically be discarded with regular non‑hazardous waste.

What makes Hanna Instruments’ calibration solution different from generic alternatives?

Hanna Instruments’ solution is produced under strict quality‑control protocols, providing traceability to national standards, a longer shelf life due to its antimicrobial formulation, and comprehensive technical support that generic brands often lack.
