## Description

A box of one hundred sterile, single-use pen needles, 32 gauge and 4 mm long. Each needle sits in its own paper-tab seal, screws onto standard threaded pen-type devices and comes with the customary two-part protection of an outer shield plus an inner cap. There is no peptide, drug or liquid of any sort in the box — it is purely hardware.

The two figures that count are gauge and length. Gauge is inversely related to diameter, so 32G is among the finest widely available sizes, with an outside diameter of about 0.23 mm, and 4 mm is at the short end of pen-needle lengths. Current needles of this type generally have thin walls to keep the inner bore wide, a silicone-coated cannula and a multi-bevel lancet point — features that lower the force needed to penetrate and that distinguish one 32G needle from another far more than the gauge figure itself.

## Frequently asked questions

### What do 32G and 4 mm refer to?

32G is the gauge — the finer the needle, the higher the number — here about 0.23 mm outside diameter, among the thinnest in common use. 4 mm is the length of the cannula from hub face to tip, the short end of pen-needle sizes.

### Do they fit every pen device?

They have the standard threaded hub used by most pen-type devices, hence “universal fit”. A few proprietary devices use their own threads or a bayonet mount, so check compatibility with your device before buying larger quantities.

### How are they different from insulin syringes?

An insulin syringe is a complete unit — fixed needle plus graduated barrel. A pen needle is only the cannula, screwed onto a separate pen device that measures the volume. Choose according to the part of your workflow you are equipping, not by gauge.

### Are they sterile, and may they be reused?

Each needle stays sterile until its own paper seal is opened, and every one is for single use. Reusing it breaks sterility and bends the tip — microscope images of reused needles show visible damage after just one puncture — so discard each needle after one use.

### Is any peptide or diluent included?

No. The box contains hardware only: one hundred sterile pen needles with shields and caps. Bacteriostatic water, vials and research compounds must be ordered separately, and nothing here comes pre-filled.
