LABSOLUTE® Kjeldahl flasks with a beaded rim without standard ground joint are made of high-quality borosilicate glass 3.3. The neck diameter including rim is around 40 mm for all volumes. The flasks correspond to the standards of the European Pharmacopoeia 7 for glass type I.

The LABSOLUTE® Erlenmeyer flasks with a durable volume scale are made of high-quality borosilicate glass 3.3 and are therefore extremely temperature-resistant up to 500 °C. The wide-neck and narrow-neck flasks, as well as the flasks with standard ground joint comply with the valid standards. The flasks are resistant to cold lyes/alkaline solutions and strong acids, with the exception of hydrofluoric acid and hot, concentrated phosphoric acid.

Comply with DIN EN ISO 24450.

The LABSOLUTE® cast iron weighting rings stabilize glass and plasticware in the water bath, preventing it from floating. The red PVC plastic coating is temperature-resistant from -20 to +60 °C and reliably prevents damage to laboratory equipment.

Erlenmeyer flasks made of borosilicate glass 3.3. Screw cap with PTFE liner.

• White graduation and labelling field
• GL thread

To stabilise glassware in water or oil baths. The vinyl coating prevents vessels and apparatus from being scratched or marked.

Cellulose, 100 % biodegradable and fully compostable autoclavable. Steristoppers^® have been proved as an excellent sealing for microbiological samples and tissue cultures in test tubes and Erlenmeyer flasks. They are in constant use in many European microbiological laboratories.

• Autoclavable
• Filters bacteria
• Sterilizable
• Air permeable

DIN EN ISO 24450. With approximate graduations and beaded rim. With Retrace Code (Batch Identification), certificate available via the Internet. Uniformly wall thickness. Glass type I / neutral glass as per USP, EP and JP. Autoclavable.

DIN ISO 1773. With approximate graduations and beaded rim. From 50 ml with Retrace Code (Batch Identification), certificate available via the Internet. Erlenmeyer flasks are well suited for mixing, because of their conical shape. Uniform wall thickness distribution makes these beakers ideal for heating applications. Glass Type I / neutral glass as per USP, EP and JP. Autoclavable.

Cell culture multiwell plates are available in the hydrophilic surface (TC surface treatment) for improved cell adhesion and hydrophobic surface for suspension cultures and hybridoma cells. Cell culture microplates from the CELLSTAR® range are specifically treated. This treatment leads to polar groups such as carboxyl and hydroxyl groups , added to the plastic surface. These allow the growth of adherent cell lines. They are also suitable for automated systems and contain an alphanumeric well coding. They are also suitable for footprint systems and contain an alphanumeric well coding.

Properties:

• Lid enables gas exchange with the lowest possible evaporation
• High clarity of the clear microplates for optimal microscopic examinations
• Stackable
• Alphanumeric well coding
• Consecutive lot numbering
• 96 and 1536 well format available

New line of membrane driven flasks for high density cell culture. The flasks are designed to enhance small scale bio-production for antibodies and proteins. Conventional in vivo or in vitro cell culture methods can be laborious, may have low cell density and require significant purification. CELLine™ flasks address these three areas of limitation observed in static tissue culture flasks.

• Disposable and ready-to-use
• High cell density and high product concentration
• Reduces operation time
• Decreases use of consumables
• Cost-efficient, space saving, and stackable
• No additional equipment required for operation

• Complies with ISO 1773
• Flat base for standing on benches and hotplates etc.
• Manufactured from Pyrex^® glass for high resistance to thermal shock
• Excellent chemical durability for contamination-free performance
• With white enamel marking spot

These cell culture flasks with treated surfaces for the cultivation of adherent cells are available with different growth areas from 12.5 to 300 cm². Available with vented or plug-seal caps made from polyethylene. Vented caps contain a 0.22 µm hydrophobic filter to allow gas exchange and minimize risk of cross-contamination. Plug-seal caps can be used in closed systems, providing a liquid and gas sheer seal, but by simply unscrewing the cap one quarter of a turn, this cap can also be used in an open system.

• Innovative angled neck design offers good pipette and cell scraper access
• Upper triangular and wider base shape provides stability
• Stackable
• Special writing area near the neck
• Engraved graduation on both flask sides
• Sterilized by gamma irradiation
• Pyrogen-free
• Individually packed in resealable outer packaging with zip fastener

The surface of the tubes is coated with Thermo Scientific™ Nunclon™ Δ and designed for the cultivation of adherent cell cultures. With cap made of PE.

• Tubes with flat side provide 5.5 cm²culture surface
• Suitable for microscopy, use of cover glasses possible
• Leakproof

Uniform wall thickness distribution makes these flasks ideal for heating applications and distillations. The flasks are manufactured from a hydrolytically resistant borosilicate glass 3.3, which is defined as "Type I, Class A" in the ASTM Specification E 438.
