  • Fits any standard GL-45 lid cap.
• Material: Autoclave-safe

Why Thread Size Matters

Lab bottles come in a range of thread standards, and a mismatched cap won’t seal properly — risking contamination or leakage during incubation. GL45 is one of the more common sizes used in liquid culture and media bottles, so checking your bottle’s threading before ordering ensures a tight, reliable seal.

Single-Cap Convenience

This single-cap option is a practical pickup for replacing a damaged or worn cap, or for adding one additional bottle to your setup without committing to a full multi-pack. Like our other media caps, it’s built to withstand repeated autoclave cycles, so a well-maintained cap can serve through many rounds of sterilization and use.

NOTE: 1 media cap. Please add in notes section of order if you would like a 1 liter dip tube or 2 liter tube. (or 10 liter dip tube)
