APERA INSTRUMENTS / AI4203
TN400-S3 silicone oil is the Apera accessory for exterior care of turbidity sample and calibration vials. Apply a small drop to the outside of the vial, spread it evenly and remove excess according to the meter manual. It is not a sample additive or a calibration solution.
Apera identifies TN400-S3 for care of both sample vials and standard-solution vials used in turbidity testing.
The TN400 and TN480 manuals call for a small drop spread over the outside surface with a lint-free cloth, followed by removal of excess with filter paper or high-quality tissue.
The exact TN400-S3 manufacturer photograph labels the bottle Qty: 10ml. The replacement-parts tables also identify TN400-S3 as one 10 mL bottle.

These are documented parent-meter workflows, not meters supplied with this accessory. Match the part number and required calibration or vial procedure.

Parent turbidity meter. The meter and other accessories are separate from this order.
Treat the exterior of standard vials and sample vials consistently. Keep sealed nonzero standard vials closed during surface care.
The parent manuals state that oil need not be applied for every calibration or reading. Follow their several-day to weekly guidance; clean the exterior between treatments as directed.
Clean reused sample vials internally by the separate detergent-and-rinse procedure. Silicone oil is the exterior treatment, not a substitute for removing sample residue inside the vial.
Use TN400-S3 for the documented vial-exterior treatment. The bottle label states to keep it away from oxidizers; follow the supplied label and applicable safety information.
Use only a small amount and remove excess. Keep nonzero calibration standards sealed and use the separate interior-cleaning procedure for reusable sample vials.
For warranty information or return authorization, contact Blue Tiger Scientific before sending any item. Do not assume that the parent meter warranty applies to a separately purchased accessory.
It is silicone oil for exterior care of sample vials and calibration vials used in turbidity testing. Follow the applicable Apera meter instructions.
The exact standalone manufacturer photograph labels the bottle Qty: 10ml. The TN400 and TN480 replacement-parts tables independently identify TN400-S3 as one 10 mL bottle.
No. The documented procedure applies the oil to the outside of the vial. It is not added to the liquid being measured or to the calibration standard.
Apply a small drop to the outside surface, distribute it with a lint-free cloth, then wipe off excess with filter paper or high-quality tissue as directed in the meter manual. Excess residual oil can affect measurements.
No. The TN400 and TN480 manuals say oil is not necessary for every calibration and measurement. They describe application every several days or once a week, with exterior cleaning between treatments.
Yes, on the exterior. Treat sample and calibration vial surfaces consistently. Do not open sealed nonzero standard vials to apply oil.
No. Reused sample vials need the separate detergent-and-rinse cleaning procedure in the meter manual. Exterior oil treatment does not remove internal sample residue.
Do not treat oil as a repair for a damaged vial. The meter instructions require clean, scratch-free sample vials; inspect the vial and replace unsuitable ones rather than relying on oil to restore them.
