Specifications and selection guide
Choosing the right spare part or lab accessory starts with confirming the equipment brand, model, part number and required product type. For replacement components, check dimensions, thread size, joint size, material, seal type and compatibility with the original equipment. For accessories such as probes, calibration solutions, tubes, vials, markers or attachments, confirm the intended instrument, sample type, operating conditions and package quantity. Since this category includes many product types across multiple pages, filtering by brand, part number and product name is the safest way to narrow the selection.

Frequently Asked Questions
How do I make sure a spare part will fit my lab equipment?
Check the equipment brand, model number and manufacturer part number before ordering. Many lab equipment spare parts are designed for a specific instrument or product line, so the safest option is to match the listed part number with the documentation for your existing equipment. Even when two parts look similar, differences in dimensions, materials or connection points can affect compatibility.
What should I check before ordering replacement seals, caps or O-rings?
Before ordering seals, caps, O-rings or similar replacement parts, confirm the material, size, connection type and chemical compatibility. Small differences in diameter, thread size or elastomer type can affect sealing performance and may make the part unsuitable for your equipment. O-ring sets are often sized to a specific stopcock or joint series.
When should I replace worn lab equipment parts?
Replacement may be needed when parts show wear, cracking, leaks, poor sealing, unstable operation, contamination risk or reduced performance. Components such as seals, plugs, bushings, bearings, impellers and tubing should be inspected regularly according to the equipment manufacturer's recommendations.
What should I do if I cannot identify the correct replacement part?
If you are not sure which spare part or accessory is compatible with your equipment, check the equipment manual, original part number or product label first. You can also contact Selectum LLC with the equipment brand, model number, part number and application details to help narrow down the correct option.
