APERA INSTRUMENTS / PH60-MS / AI3725
The smaller sensing end is only part of the small-volume story. PH60-MS combines a semi-micro LabSen 246-5 pH/temperature electrode with the supplied container method so both the glass and reference junction can contact the sample.
Choose this kit for a defined small-volume or test-tube workflow. Apera’s 60 µL minimum is conditional on the supplied semi-micro container and required junction coverage, not a universal minimum for every vial.
LabSen 246-5
Supplied electrode
Replacement AI3235
0.01 pH
Meter resolution
Meter accuracy: ±0.01 pH ±1 digit
8-pin
Matched external connection
Not an ordinary BNC-only substitution
Choose by the sample and the supplied LabSen electrode. Each card opens that model’s product page; optional compatibility does not mean an extra probe comes in the box.
AI3723
Low-ionic / pure water
LabSen 805; sample handling matters.
AI3721
Wastewater / dirty liquids
LabSen 335; open-junction routine.
AI3725
Small sample volumes
LabSen 246-5; vessel and junction contact.
AI3733
Viscous liquids
LabSen 855; reference selected for the matrix.
AI3727
Salty / alkaline water
LabSen 845; pH, not salt concentration.
AI3731
Hot / caustic water
LabSen 865; separate probe and meter limits.
AI3729
Limited-HF sample work
LabSen 835; all chemistry/time bounds apply.
AI3735
Meat / solid foods
LabSen 765; blade-sheath sampling method.
SMALL VOLUME IS A VESSEL-AND-CONTACT CLAIM
Apera’s minimum uses the supplied semi-micro container and requires the liquid to cover the white reference-junction spot as well as the glass. A wet sensing tip alone is not enough.
The stated 6mm is a sensing-tip dimension, not the diameter of the whole electrode assembly.
Junction coverage and container geometry determine contact; do not infer a different vial’s minimum from 60 µL.
PH60 meter body, LabSen 246-5 external pH/temperature electrode, CalPod solution organizer, pH 4.00, 7.00 and 10.01 buffers, 3M KCl storage solution, protective cap, instructions and carrying case, plus the semi-micro container. Four AAA batteries are factory-installed per the model’s preparation instructions.
The current US kit buffer set is pH 4.00, 7.00 and 10.01. Match that working set to your sample and calibration method; do not assume every specialized PH60 package contains the same buffers.
SAMPLE FIT BEFORE FEATURE COUNT
Use the supplied container method when working near the stated minimum. Wetting only the glass does not complete the reference contact.
Check vessel opening, probe geometry and liquid height. The 6mm sensing tip does not mean the whole assembly fits every 6mm opening.
Keep sample preparation, junction coverage and carryover control consistent. Vessel geometry can matter as much as nominal microliters.
Semi-micro sensing tip; 6mm tip diameter is not the overall probe diameter. The ceramic junction and its sample contact are part of the method, not a universal chemical-compatibility or maintenance-free guarantee.
The volume claim belongs to a specific container/contact method. It is not permission to lower the liquid below the junction, not an arbitrary-vial guarantee and not a dimension for the entire electrode shaft.
Use the supplied semi-micro container for the 60 µL claim and ensure liquid covers the white reference-junction spot as well as the glass. For other vessels, evaluate geometry and required immersion rather than extrapolating that minimum.
Use the specified kit buffers and current instructions. Start at neutral as directed, then choose the appropriate additional points. Do not infer an included ORP or EC probe.
Keep glass and junction in contact with a representative sample, limit carryover, and wait for a stable reading under the defined method.
The current US specialized-kit manual specifies a PH60 display range of -2.00 to 16.00 pH, 0.01 pH resolution and ±0.01 pH ±1 digit meter accuracy. Those numbers do not by themselves establish probe-range, chemical compatibility or total method accuracy.
Temperature measurement/ATC is 0-100 °C in these current US kit instructions. A higher electrode-only temperature figure does not extend that electronic interval or validate every part of the assembly in the sample.
0-100 °C electrode rating in reviewed current US sources; verify whole assembly/sample method
The listed LabSen 246-5 is non-refillable. Its internal reference/electrolyte description is separate from the external 3M KCl storage vial. Do not open/refill the reference because a chemical name appears in a table.
Rinse before and after measurements without rubbing the glass. Use contaminant-specific manufacturer care rather than an improvised chemical recipe; after deep cleaning follow the required rehydration and recalibration sequence.
Store the probe in its tightly closed vial with the specified 3M KCl solution, not tap, RO, distilled or deionized water. Keep solution fresh and the connector clean/dry. A dry or poorly stored probe needs the model’s recovery routine before calibration.
Apera’s electrode-family introduction explains the general technology. It is not an exact PH60-MS operating tutorial; use this kit’s current manual for sample preparation, limits and care.
These are separate instruments for different water-measurement tasks, not substitute specialized electrodes for PH60-MS. A general-water meter link does not establish HF, caustic, hot-process or direct-food compatibility.

No. The US manual’s 60 µL claim uses the supplied semi-micro container and requires the white junction spot to be covered. Other vessels need their own geometry/contact assessment.
PH60, LabSen 246-5, semi-micro container, CalPod, pH 4.00/7.00/10.01 buffers, 3M KCl, cap, instructions and case are listed. The model-specific preparation indicates four AAA batteries are installed.
pH measurement needs the sensing membrane and reference pathway to contact the sample. A wet glass tip alone does not establish correct reference contact.
No. It is the sensing-tip diameter, not a claim that the whole shaft or connector fits a 6mm vessel opening. Check the exact probe and vessel geometry.
The current US kit manual specifies 0.01 pH resolution and ±0.01 pH ±1 digit meter accuracy. Correct contact, calibration and sample-method effects remain separate.
No. It is a non-refillable semi-micro electrode. Internal gel/electrolyte wording is not a refill instruction.
The exact replacement is LabSen 246-5, AI3235, with 8-pin connection. Do not assume a similarly named adjacent BNC semi-micro model fits the PH60 socket.
Keep the storage vial tightly closed with specified 3M KCl, not pure water. Rinse carefully, avoid rubbing the glass, and follow the current instructions for cleaning, rehydration and recalibration.
Review PH60-MS and its LabSen 246-5 configuration, then return to the price and ordering controls. Blue Tiger Scientific can help clarify exact kit, probe and method requirements before ordering.
APERA INSTRUMENTS, LLC warrants this instrument to be free from defects in material and workmanship and agree to repair or replace free of charge, at the option of APERA INSTRUMENTS, LLC, any malfunctioned or damaged product attributable to the responsibility of APERA INSTRUMENTS, LLC for a period of TWO YEARS for the instrument and SIX MONTHS for the probe from the delivery.
This limited warranty does NOT cover any issues due to:
Use the current US exact-kit manual for the supplied configuration and operation. The LabSen handbook is additional method/selection reference, not a replacement for those instructions. Each card opens a PDF in a new tab.
