BRAND seripettor bottle-top dispenser ® | 2.5–25 ml | Item No. 4720150

Efficient dispensing of medium volumes

The BRAND seripettor ® (2.5–25 ml) is the ideal choice for any laboratory seeking a cost-effective and robust solution for dispensing volumes of up to 25 ml. This instrument bridges the gap between microvolumes and large volumes and is perfectly suited to routine use. Whether nutrient solutions, buffers or agar media – the seripettor ® delivers reliable results at minimal cost per dispensing operation.

Automatic refilling for batch work

The integrated return spring really comes into its own with volumes up to 25 ml: it automatically lifts the piston after each dispensing stroke and refills the cylinder on its own. This enables fast, effortless operation, even during long dispensing runs. The desired volume can be set in a flash and without the risk of mix-ups via the mechanical rack and pinion.

Specialist for culture media and more

Thanks to its special combination of materials and design, the seripettor ® is particularly versatile:

• Culture media: Agar media can be dispensed without any problems up to a temperature of 60 °C.
• Biological reagents: Perfect for buffer solutions, detergents, vitamin solutions or hydrogen peroxide.
• Acids & alkalis: Suitable for weakly concentrated or diluted acids and alkalis (e.g. NaOH, KOH).
• Solvents: Compatible with polar solvents such as ethanol, methanol or acetylacetone.

Maintenance in seconds

A key advantage in the demanding day-to-day laboratory environment is the replaceable dosing unit. If the unit becomes contaminated or worn due to crystallising media, there is no need to send the device in for repair. Simply replace the entire dosing unit (cylinder and piston) without the need for tools – hygienic, cost-effective and ready for immediate use again.
