Frequently Asked Questions

Why choose a narrow mouth?

The narrow opening gives controlled pouring, less spillage and less evaporation, which suits liquid reagents. For powders and solids, a wide mouth bottle is easier to fill and empty.

What does US FDA 21 CFR conformity mean?

The manufacturer states the polypropylene meets US FDA 21 CFR requirements for materials in contact with food and pharmaceutical products, so no harmful substances are expected to leach into contents.

Is it autoclavable?

Yes. The manufacturer states polypropylene can be autoclaved at 121 °C, filled or empty. Loosen the cap slightly first so pressure can equalise.

Which chemicals is it suitable for?

Polypropylene resists aqueous solutions, many acids and bases, alcohols and many common solvents. It is not recommended for strong oxidisers or for strong non-polar solvents such as toluene, xylene and chloroform. Check a chemical resistance chart or test a sample first.

Is the cap leakproof?

The cap has a built-in seal ring that compresses against the bottle neck and, when tightened properly, is stated to prevent leaks even if the bottle is inverted or shaken.

What sizes and packs are available?

4 to 60 ml in packs of 100; 125 to 500 ml in packs of 12; 1000 ml in packs of 6.

Do you provide a GST invoice and bulk or institutional quotation?

Yes. A GST invoice is provided with every order, and quotations for colleges, hospitals, pharma companies and government labs, including bulk orders, are available on request.

What is the HSN code?

HSN code 39233090.

Is the price per piece or per pack?

The price is for the full pack shown in the variant name (for example Pack of 12). Single pieces are not sold separately.

What is the delivery time?

Delivery time depends on stock and your location. Contact us for a confirmed date; freight is charged extra.
