J.P. Pöllath - Labor-Technologie is a specialized German manufacturer of essential laboratory consumables and technical aids, headquartered in Blaustein. For decades, the company has focused on a niche but critical mission: providing high-performance solutions for distillation, synthesis, and the maintenance of precision glassware. J.P. Pöllath is internationally recognized for its expertise in "boiling technology" and specialized lubrication, ensuring that complex chemical reactions can be carried out safely and without interruption. Their guiding principle centers on reliability and absolute material resistance, which is reflected in their development of high-purity boiling stones and silicone-free greases that prevent the sticking and abrasion of ground glass joints. Today, J.P. Pöllath remains a vital partner for analytical, biochemical, and industrial laboratories worldwide, delivering "Made in Germany" technical aids that protect expensive equipment and ensure reproducible scientific results.
The J.P. Pöllath range at LabFriend features professional distillation, separation, and filtration solutions, headlined by their specialized Type A, Type B, and "Resistant" boiling stones. These boiling chips are essential for preventing "bumping" and ensuring smooth boiling even under vacuum or in the smallest liquid volumes. For laboratory equipment maintenance, the brand provides advanced general laboratory aids, featuring the world-renowned ALSIROL® and KaWeS joint greases. These silicone-free lubricants are critical for sealing rotating joints and protecting precision-cut sleeves from glass abrasion across a wide temperature range. Their portfolio also encompasses essential sample preparation tools, such as specialized clay squares for safe heating and individual air regulators (HM-2) for vacuum capillary tubes. By choosing J.P. Pöllath through LabFriend, you benefit from competitive pricing and fast shipping on specialized technical aids designed for ultimate durability and chemical resistance.
Why Choose J.P. Pöllath for Your Laboratory?
- Niche Material Expertise: J.P. Pöllath specializes in high-purity materials like ceramic and specific mineral-based boiling stones that offer absolute resistance to strong acids and oxidizing agents.
- Advanced Silicone-Free Lubrication: Their ALSIROL® grease is a favorite in analytical labs because it contains no silicone derivatives, preventing contamination of sensitive samples and ensuring no gumming or polymerization.
- Extreme Temperature Stability: Most Pöllath lubricants and boiling aids are designed to perform reliably in a temperature range from -40°C to +200°C, making them suitable for both cryogenic and high-heat applications.
- Safety-First Engineering: From the development of non-sharp clay squares to capillary air regulators, the brand focuses on reducing common laboratory risks such as glass breakage and eye injuries from splinters.
- German Technical Standards: All products are manufactured in Germany according to strict quality protocols, ensuring consistent grain size in boiling stones and optimal viscosity in grease films.
Frequently Asked Questions
1. What is the difference between Type A and Type B boiling stones?
Type A boiling stones are typically natural products developed for preparatory work and reflux in neutral or alkaline solvents. Type B stones are ceramic products with higher purity and abrasion resistance, specifically intended for analytical work where contamination must be avoided.
2. Can I use ALSIROL® joint grease under high vacuum?
Yes, ALSIROL® has a very low vapor pressure (0.00001 mbar), making it exceptionally suitable for use in high-vacuum distillations and for sealing stirring systems with both glass and metal shafts.
3. Are J.P. Pöllath boiling stones reusable?
For analytical purposes, it is generally recommended to use fresh boiling stones for each new distillation to ensure maximum effectiveness and prevent cross-contamination. However, certain "Resistant" types can be sterilized by annealing if necessary.
4. Why choose clay squares over traditional clay plate fragments?
Pöllath clay squares are designed to be easily broken off by hand without creating sharp, pointed splinters. This minimizes the risk of eye injuries and prevents leftover glass-damaging debris on the work surface.
