Bis(2-methoxyethyl)+ether
Supplier:
HICHROM
Description:
Everest columns have unique selectivity and sensitivity, which are the result of bonding technology that improves C18 surface coverage and deactivates residual silanols. Previously, the 300 Å C18 chemistries had carbon coverage in the 2,8 to 3,6 µmol/m² range. Everest C18 coverage is in excess of 4 µmol/m² and approximates the theoretical limit based on surface area. The increased shielding of the base silica increases column lifetime and reduces the amount of TFA required to shield the silica.
Supplier:
LABCONCO
Description:
Designed to handle the lyophilisation needs of research laboratories. Collectors that reach −50 °C are available with capacities from 1 to 18 litres. Cascade systems in 2,5, 4,5, 6 and 12 litre collector capacities that reach −84 °C are ideal for freeze drying samples with low eutectic temperatures. The FreeZone® −105 °C bench top freeze dryer systems are suitable for samples with very low eutectic points including ones containing small amounts of methanol or ethanol.

JULABO GMBH
Description:
High temperature circulators can be used for temperature applications up to 400 °C; units provide powerful heating capacities for shortest heat-up times and rapid compensation of endothermic reactions. Applications include use with reactors, autoclaves, distillation columns, mini plant installations, pilot plants and production facilities. Because of the closed circuit system oxidation is reduced and unpleasant odours and vapours do not escape, even at high temperatures.
Catalog Number:
(611-2396)
Supplier:
OHAUS
Description:
A range of four-place balances that incorporate a touch screen, advanced weighing and proximity sensor technologies. The easy to use control unit can be mounted on a base, above a base on an optional column, on a wall, or remotely (up to 3 metres distance with an optional cable). The touch screen display, with universal icons and informative prompts, simplifies set-up functions and basic operation. The operator has the added choice to use proximity sensors for hands-free operation when handling sensitive samples. These balances have multiple application modes from basic weighing to SQC applications, together with short stabilisation times and optimised performance specifications.

Supplier:
IKA JANKE KUNKEL
Description:
Laboratory stirrers designed for simple stirring tasks for quantities up to 15 or 25 L (EUROSTAR 20 digital and EUROSTAR 40 digital), or for intensive stirring tasks for quantities up to 20 L (EUROSTAR 20 high speed digital). Units automatically adjust the speed through microprocessor controlled technology within the speed range of 0/30 to 2000 min⁻¹ (or 0/150 to 6000 for the high speed model). Safety circuits ensure automatic cut off in anti-stall or overload conditions. The actual shaft speed and preset speed are constantly monitored and variations are adjusted automatically. This guarantees a constant speed even with changes in sample viscosities.

Sartorius Balances
Description:
Advanced balances designed for easy, reliable and secure weighing operations for regulated areas. These analytical balances deliver stabilisation times of 2 to 3 seconds with excellent repeatability (0,1 mg) and linearity (0,2 mg). The Secura® range features a range of APC functions (Advanced Pharma Compliance) to help with documentation and monitoring requirements. GLP-compliant printout documentation is also controlled by the built-in security control, as data transfer to a printer or PC is blocked, when common operating errors occur, such as when the balance is not level, minimum sample weight has not been achieved or temperature fluctuations require isoCAL calibration adjustment.
