Insulin Syringes 31G x 6 mm Philippines | 1 mL and 0.5 mL Research Laboratory Syringes

Insulin-type syringes with a fixed 31G x 6 mm needle, supplied in the Philippines by Regenwell PH. Sterile, individually sealed, single-use syringes in 1 mL and 0.5 mL sizes, sold singly at ₱10 or by the box of 100 at ₱600. The syringe format used in every Regenwell Complete Set, now available on its own for laboratories that order the Vial + BAC Water format or need to restock. Ships nationwide with tracking. GCash, Visa/Mastercard, bank transfer, or Cash on Delivery on orders from ₱2,500. For laboratory and research use only. Not for human or animal use.

What is it?

A fine-gauge, low-volume syringe with the needle permanently fixed to the barrel. The 31G needle is one of the thinnest standard gauges and the 6 mm length is the short format. Both sizes use a U-100 insulin-style scale, which is why this type of syringe is the laboratory standard for drawing and measuring small, precise volumes of reconstituted research peptide solution. Each syringe is sealed in its own sterile wrapper and is intended for a single draw.

1 mL or 0.5 mL?

Both have the same 31G x 6 mm needle; the difference is the barrel and its scale.

• 1 mL: 100-unit barrel, graduated in 2-unit (0.02 mL) steps. The general-purpose choice; it covers larger draws and anything up to the full millilitre.
• 0.5 mL: 50-unit barrel, graduated in 1-unit (0.01 mL) steps. The finer scale makes small volumes easier to read accurately, which suits concentrated solutions where the draw is a few units.

If in doubt, 1 mL is the safer default; 0.5 mL earns its place when the measured volume is routinely under 0.3 mL and precision matters more than capacity.

Sizes, packs and pricing (PHP)

Singles are for topping up an order. The box of 100 is the sensible unit for any laboratory running a multi-week protocol; it is 40% cheaper per syringe and counts toward the ₱10,000 free-shipping threshold. No brand is specified; we supply a standard sterile insulin-type syringe from our current stock, and the product photos show the format currently shipping.

How it is used in research

Research peptides in our catalogue are supplied as lyophilised powder and reconstituted with bacteriostatic water. Once in solution, the working volume for a laboratory sample is usually a fraction of a millilitre, so an insulin-type scale is the practical way to measure it. The same syringe is used to transfer diluent into the peptide vial during reconstitution. One syringe per draw; do not reuse. Our reconstitution and concentration reference shows how units on the barrel relate to milligrams of peptide at a given concentration.

Shipping, payment and packaging

• Delivery: nationwide by tracked J&T courier. Orders paid by 12 noon, Monday to Saturday, ship the same day; later payments ship the next business day. After dispatch: Metro Manila 1 to 2 business days (or same-day Lalamove), Luzon provinces 2 to 4 business days, Visayas and Mindanao 5 to 7 business days. Full details in our shipping policy. Any pre-order or dispatch-lead-time notice shown on this page takes precedence.
• Free shipping by J&T on orders of ₱10,000 or more.
• Payment: GCash, bank transfer, or Visa/Mastercard through a secure Wise payment link. Choose the method at checkout; the payment details appear on the confirmation page and in your order email, and your order ships once payment is received. Cash on Delivery is available on orders from ₱2,500 to ₱9,999.99: choose the Cash on Delivery (JnT) shipping option (₱250) and then COD as the payment method. Orders of ₱10,000 or more are prepaid only.
• Packaging: each syringe is factory-sealed in its own sterile wrapper. Singles are packed flat with the rest of the order; boxes ship in the manufacturer's carton. Outer packaging is plain, with no product branding.
• Order changes: orders can be changed or cancelled within 2 hours of placement, before packing.

Storage and handling

Store sealed syringes at room temperature in a dry place, away from direct light. Keep the wrapper intact until the moment of use and discard any syringe whose wrapper is torn or whose needle cap is loose. Used syringes are sharps: cap only with a proper safety technique or not at all, and dispose of them in a puncture-resistant sharps container in line with local waste rules.

Frequently asked questions

Are these the same syringes that come in the Complete Set?

Yes, same format. Buy them here when you order the Vial + BAC Water format, or when a protocol runs longer than the set's supply.

What does 31G x 6 mm mean?

31G is the needle gauge (higher number, thinner needle); 6 mm is the needle length. It is the fine, short combination most laboratories prefer for low-volume work.

Can the needle be removed?

No. The needle is fixed to the barrel, which minimises dead space and keeps the measured volume accurate. If you need a detachable needle, this is not the right syringe.

Do you sell other gauges or lengths?

Not at present. 31G x 6 mm is the only format we stock. Message us if your work needs something different.
