Science Lab Plasticware Lab Equipment Manufacturer, Supplier and Exporter in India

Ray Export's science lab plasticware listing runs from SLPW-0001 to SLPW-0050 in alphabetical order. Most items are moulded in polypropylene, which is lighter than glass and autoclavable, and the range covers vessels and funnels, cryogenic storage, molecular model sets, microbiology consumables and animal housing.

What this listing holds

Points to compare before ordering

• Autoclavability is stated per item rather than across the range, so check the item page if the vessel must be sterilised.
• Polypropylene against polycarbonate: the cryo boxes are offered in both, and the two differ in clarity and low-temperature behaviour.
• The burette is acrylic with a PTFE plug rather than glass, which makes it lighter and less fragile for teaching use.
• Several items are offered in a standard and a Euro Design version, including the beakers and atomic model sets, so compare the two before ordering.
• The listing is alphabetical and ends at M, so if you are looking for an item later in the alphabet ask the sales team whether it is held.
• Glass equivalents of most of these vessels are listed under Chemistry Lab Instruments, so choose on chemical resistance and heating needs.

Frequently asked questions

Is everything in this listing autoclavable?

No, and that is the single most important thing to check. Autoclavability is stated per item rather than across the range, because the range mixes polymers. Polypropylene items take the usual 121 deg C cycle; the acrylic burette body does not, and polycarbonate ages with repeated cycles. Read the item entry before you put anything in a load, and tell us at the quotation stage which items have to be sterilised so we can confirm each one in writing.

The cryo boxes come in both polypropylene and polycarbonate - which should I take?

Both are listed (SLPW-0022 and SLPW-0023) because they answer different needs. Polycarbonate is clearer and more rigid, so contents and labels read easily through the lid and the box holds its shape in a crowded rack. Polypropylene is more chemically resistant and more forgiving of repeated rough handling. Tell us the storage temperature and whether the boxes sit in the liquid or vapour phase, and we will recommend between them.

Why is the burette acrylic rather than glass?

SLPW-0009 is an acrylic body with a leak-proof stopcock and a self-lubricating PTFE plug, and it is individually calibrated. The point of it is that it will not shatter, which matters in a teaching laboratory where a broken glass burette is both a hazard and a repeat purchase. Glass remains the right choice for solvents that attack acrylic and where the highest accuracy class is required. Ask for the calibration class and the stated tolerance so you can compare it against the glass alternative.

Can plastic replace laboratory glass across the board?

Not across the board, and it is worth being clear where the line falls. Plastic is lighter, it does not shatter, and in polypropylene it autoclaves - which makes it the better answer for storage, sample handling, cold work and anywhere a dropped vessel is likely. No plastic matches borosilicate glass for solvent resistance, for optical clarity that survives years of cleaning, or for direct heating on a flame or hotplate. The sensible split is plastic for handling and storage, glass where heat or aggressive chemistry is involved.

What should I state when I ask for a quotation?

Catalogue number, capacity and quantity for each line, and a note against any item that must be autoclaved. For the cryogenic items add the storage temperature and the phase. For the model sets state the syllabus level, since that decides which set fits. If you are mixing plastic and glass in one order, say so, because lead times on the two differ and we would rather tell you that up front than hold the whole order for one line.

What level are the molecular and crystal model sets for?

SLPW-0004 and SLPW-0005 are ball-and-connector atomic model sets for demonstrating compounds, and SLPW-0028 is a crystal model set. What decides whether a set fits your syllabus is the atom count, the colour convention and which bond angles the connectors allow, so ask for those three rather than ordering by name. A set that cannot make the specific molecules on your syllabus is an expensive box of parts.

Key takeaways

• Ask which polymer on every line. Polypropylene, polycarbonate and acrylic all appear in this one listing and they are not interchangeable.
• Autoclavability is per item here, not a property of the range. Check it before a load, and have it confirmed in writing for the items that need it.
• Polycarbonate for clarity, polypropylene for chemical resistance - which is exactly why the cryo boxes are offered in both.
• The burette is acrylic with a PTFE plug: unbreakable and individually calibrated, but not a glass substitute for aggressive solvents or the tightest accuracy class.
• Plastic for storage, handling and cold; glass where heat or solvents are involved. That split, decided deliberately, saves more money than choosing either one everywhere.
• Order by catalogue number, capacity and quantity, and specify the model sets by atom count and bond angles rather than by name.

Polymer behaviour is described here at the level of standard laboratory reference practice, as guidance for specifying, and is not a product claim. The polymer, autoclavability, capacity tolerance, calibration class and model-set contents of any specific item will be confirmed in writing on the quotation before an order is placed. Note that this listing is displayed in alphabetical order rather than by catalogue number, so SLPW codes do not appear in sequence on the page. No price is quoted here; prices depend on specification, quantity and destination and are issued as dated written quotations.
