Description: BrandTech Titrette Bottle-Top Burette, 25 mL
Part Number: 4760151
The BRAND Titrette® is the only bottletop burette that meets Class A accuracy specifications for glass burettes. Battery powered for portability, it handles common titrants, and is fully user-serviceable. The Titrette® bottletop burette has an innovative new measuring system which matches the Class A accuracy of glass burettes and, if needed, can offer the precision of 3 decimal places below 20mL. This is an important feature for users who need to work within the Class A error limits of glass burettes according to DIN EN ISO 385 or within volumetric tolerance per ASTM E287. The Titrette® can be quickly and easily disassembled in a matter of minutes – for cleaning, to replace the piston/cylinder, or to replace the batteries. Maintenance is easy and convenient, without the need to send it out for repair. To protect light-sensitive media, the installed clear cylinder inspection windows can be easily replaced with the supplied clip-on amber-colored windows. All components move within the housing, reducing headroom requirements. The compact design and the light weight ensure good stability. The titrating tube can be adjusted horizontally and vertically. The large handwheels provide smooth, precise control from rapid to dropwise titration. The Titrette® is available with a RS232 interface for direct transfer of data to a PC. The Titrette® is suitable for most commonly used titrants up to 1mol/L in concentration, such as potassium permanganate, silver nitrate, EDTA, sodium hydroxide and alcoholic potassium hydroxide. Ordering Information: The Titrette® bottletop burette is supplied in recyclable packaging with performance certificate, telescoping filling tube (170-330mm), recirculation tube, 2 AAA batteries, 3 polypropylene bottle adapters (45/33mm, 45/38mm and 33/NS 29-42), 2 colored light shield inspection windows, and operating manual. The Titrette® with PC interface contains the following additional items: RS232 connector cable and a CD with driver software, communication protocol, example application and a special operating manual.

Part Number: 4760261
Safe, reliable, and accurate dispensing of metered amounts of hydrofluoric acid in concentrations up to 52%. SafetyPrime®valve allows air bubbles to be purged from the system without dispensing, which reduces spurting during priming and conserves reagent. Integral safety discharge system reduces the risk of inadvertent dispensing if discharge tube is improperly mounted or missing. Equipped with a polypropylene discharge tube safety cap to help protect against reagent contact. Safety cap can be easily attached and removed, even when wearing gloves. The dispenser fluid path contains no glass components. When the instrument is used correctly, only the following materials come in contact with dispensed liquids: alumina ceramic, ETFE, PFA, FEP, PTFE, and platinum-iridium. Caution: Never use to dispense hydrofluoric acid from a glass container. Ordering Information: One-year manufacturer’s warranty. Supplied with mounting tool; discharge tube; 24mm, 28mm, 33m, and 38mm bottle adapters; telescopic filling tube (125–240mm); certificate of conformity; and operating manual.

Part Number: 40000-064
Dispensers have a unique direct displacement piston system that is chemical-resistant and provides safe, smooth dispensing. Units are designed with a unique air purging system that prevents loss of reagents and eliminates dripping or splashing of media. An exclusive reagent guard valve prohibits accidental discharge and eliminates the need for capping the discharge tube when the dispenser is not in use. The volume adjustment knob allows quick and easy setting, and locks the volume into place. The discharge tube can be turned on a 360° swivel, allowing convenient dispensing and safe positioning over the reagent label. Dispensers disassemble easily for cleaning. Automatic calibration eliminates readjustment. Fully autoclavable to 121°C (250°F). Basic dispensers have a PTFE system for broad general use. Choose a PTFE-lined dispenser for applications using hydrofluoric acid or a glass-lined dispenser for use with organic solvents. Ordering Information: Bottle-top dispensers with a 33mm neck are supplied with 24/25mm, 28mm, 38mm, and 45mm adapters. Dispensers with a 45mm neck are supplied with 28mm, 32/33mm, and 38mm adapters. Additional adapters also available separately. Adapter set 40000-072 consists of four adapters: 24/25mm (which fits only dispensers with a 33mm neck), and 28mm, 32/32mm, and 45mm adapters (which fit any dispenser). Reservoir bottle not included.
