QUESTIONS & ANSWERS TO WITEG

What is a bottle-top dispenser?

A bottle-top dispenser is a laboratory instrument designed for precise and repeatable dispensing of liquids directly from reagent bottles. It improves safety, reduces handling steps, and increases efficiency during routine laboratory workflows.

What are the advantages of a bottle-top dispenser compared to pipettes or graduated cylinders?

Bottle-top dispensers provide faster operation, higher repeatability for repetitive dispensing tasks, and reduced user fatigue. They also minimize reagent handling and help improve laboratory safety.

Which LABMAX dispenser is right for my application?

The ideal model depends on the media being dispensed:

LABMAX eco for routine laboratory use and excellent value.
LABMAX premium for maximum convenience, compatibility, and advanced features.
LABMAX airless for organic solvents and PTFE-swelling media.
LABMAX HF for Hydrofluoric Acid (HF) and highly aggressive acids.
MINISPENSOR for repetitive micro-volume dispensing from 50 µl to 2000 µl.

What is the difference between the LABMAX premium and LABMAX eco?

Both models offer reliable dispensing performance, a drip-free safety system, and autoclavability. The LABMAX premium adds enhanced functionality, universal chemical compatibility, integrated recalibration, and a patented closed-circuit air purging system for maximum convenience in demanding laboratory environments.

Why use an airless dispenser for organic solvents?

Many organic solvents can cause conventional PTFE pistons to swell, increasing friction and reducing service life. The LABMAX airless features a non-contact piston system specifically designed for solvents and PTFE-swelling media, helping ensure smooth operation and long-term reliability.

Why is a dedicated dispenser required for Hydrofluoric Acid (HF)?

Hydrofluoric Acid attacks glass components found in many standard dispensers. The LABMAX HF is specifically engineered with HF-resistant materials such as PTFE, sapphire, and platinum-iridium components, enabling safe and reliable HF dispensing.

How does the LABMAX zero-loss air purging system work?

Selected LABMAX models feature a closed-circuit air purging system that allows air bubbles to be removed while returning the liquid directly to the reagent bottle. This minimizes reagent waste and reduces chemical exposure during priming.

Are LABMAX dispensers compliant with DIN EN ISO 8655-5?

Yes. LABMAX dispensers are designed to meet or exceed the requirements of DIN EN ISO 8655-5. The LABMAX premium, LABMAX airless, and LABMAX HF achieve performance that exceeds the standard's specified error limits, supporting reliable and reproducible laboratory results.

Can LABMAX dispensers be sterilized?

Yes. LABMAX eco, LABMAX premium, LABMAX airless, LABMAX HF, and MINISPENSOR are fully autoclavable at 121 °C, enabling sterilization and decontamination for laboratory applications requiring high hygiene standards.

What is the MINISPENSOR and when should it be used?

The MINISPENSOR is a compact fixed-volume dispenser designed for rapid, repetitive micro-volume dispensing. It is particularly suitable for medical, biochemical, diagnostic, and life-science laboratories where speed, repeatability, and reduced consumable costs are important.
