Buying guide

Because this category gathers unrelated items under one heading, the first thing to settle is which kind of supply you are actually buying, since the questions that matter differ completely between a water purification system and a box of pipette tips. For a consumable, the decision rests on fit and volume: a tip has to match the pipette brand and the volume range, a slide box has to match the slide format, and getting that wrong wastes a whole order rather than a single part. For a capital item such as an ultrapure water system or automation equipment, the specification is where the money goes and where a mistake is expensive.

On an ultrapure water system the figure that decides the purchase is the output quality, stated as resistivity at 18.2 megohm-centimetre for Type I water, together with the flow rate and the daily volume it can produce. A system sized for a few litres a day will not feed a busy molecular biology bench, and one sized for a department is overkill for a single user. Check which purification stages are fitted, since reverse osmosis, ion exchange and UV each remove different contaminants, and check what the replaceable cartridges cost over a year, because the running cost often exceeds the purchase price.

What to verify on a used unit depends again on the item. A used water system has consumable cartridges and UV lamps that reach the buyer part-way through their life, so ask when they were last changed and factor the replacement into the price. Automation equipment should be checked for the software and licence that drives it, since the hardware is useless without the controller it was sold with. Consumables raise a different question: confirm they are sealed and within date, because an opened or expired lot of sterile tips is not usable.

The price band here is the widest of any category, running from EUR 1 for a single consumable to EUR 86.089 for a complete automation platform, with an average near EUR 1.130. What a unit costs therefore tells you little until you know which end of the category it sits in. A buyer on a tight budget will find most consumables and small accessories sit at the low end, where used and refurbished stock listed for sale runs below new. The brands that occupy the range, Various, Globe Scientific, Thermo Scientific, Millipore, VWR, span from general consumable houses to the water and purification specialists at the upper end.

Types of Laboratory supplies - other

Which supply types are listed in this category?

Among the listings that specify a type, the most common are laboratory water purification system, ultrapure water system, laboratory consumables, microscope slide storage box, pipette tips, laboratory automation equipment. Laboratory water purification systems and ultrapure water systems sit at the capital end: the first produces Type II or Type III water for general use such as media preparation and glassware rinsing, the second produces Type I ultrapure water for the most sensitive work. That ultrapure grade feeds molecular biology directly, where it goes into PCR reagent mixes, electrophoresis buffers and the final rinses in protein purification, and into genomics and proteomics workflows where a trace contaminant can ruin a run. Microscope slide storage boxes serve histology, holding stained sections through long-term archiving and retrieval. Pipette tips are the consumable behind almost every liquid-handling step, from a manual pipette on the bench to the deck of an automated platform, and filtered tips are standard in cell culture and immunoassay work where cross-contamination has to be prevented. Laboratory automation equipment, the liquid handlers and robotic platforms, is what scales molecular diagnostics and high-throughput screening from a handful of samples to thousands.

The brands behind these laboratory supplies

The brands most present here are Various, Globe Scientific, Thermo Scientific, Millipore, VWR. The "Various" and Globe Scientific presence reflects the consumable weight of the category, where tips, tubes and storage are sold in bulk rather than by model, so a buyer compares price and fit rather than a datasheet. Thermo Scientific, Millipore and VWR reach into the equipment end, with Millipore in particular known for water purification, which means parts and replacement cartridges for those systems are easier to source and a given model is straightforward to compare against its specification. A broad brand mix at the consumable end keeps prices competitive; a recognised name at the equipment end makes service history and compatibility easier to check.

What a used laboratory supply costs here

The split is heavily toward used stock: 1392 of the listings are used against 103 new, so 93 percent of the catalogue is pre-owned. Prices run from EUR 1 to EUR 86.089. That spread covers the full distance from a single disposable consumable to a complete automation platform, which is why the average near EUR 1.130 says more about the mix than about any one item. Used and refurbished stock is listed below new prices across the category.
