✅ Universal Test Kit Compatibility:

Never worry about brand sizes again. The Hub features 17.6mm primary wells that perfectly hold flat-bottom NT Labs and Colombo vials. Using an API Master Test Kit? Simply drop in our custom adapter sleeves to securely cradle your 13mm glass tubes.

✅ Hygienic Test Tube Drying Pegs: Stop putting wet tubes back into dark boxes where bacteria breeds. Our dedicated drying pegs suspend your glass test tubes upside-down, allowing them to air-dry perfectly clear.

✅ Integrated Cap Storage Trough: A sleek, rounded front tray securely holds your caps, measuring scoops, and cleaning brushes so they never roll off the table or get lost under your aquarium filter.

✅ Free 5ml Water Testing Syringe & Mount: Stop guessing your water volumes. Every Hub features a precision-engineered side U-slot to hold your syringe. To get you started immediately, we include a free 5ml water sampling syringe in every box.

✅ Integrated Colour Card Slot: A custom-engineered rear recess securely holds your brand's colour chart directly behind the testing vials. This allows for effortless, hands-free reading and perfect color matching in any lighting condition without getting your card wet.
