ALDRICH HPLC SOLVENT RESERVOIR SYSTEMS
On this page:
Four Valve Caps • Three
Valve Caps
Three Hole Caps • Accessories
Features:
- Safety coated with autoclavable PVC
- Protects light sensitive materials to 385nm
- Fingertip controls for easy, precise control
- Specially designed valves and connections assure leak free operation
- Low profile minimizes chance of tipping
- Reservoir indents improve mixing
- Reference graduations allow run time calculations
HPLC systems with four valve caps
Valves controlling
helium sparge, venting, vacuum and solvent delivery are conveniently located
on the front of the cap. All tubing connects to the back of the cap, minimizing
clutter. Uses standard 47mm diameter filter membranes. Available as standard
(PTFE/PP O-rings) or THF-resistant systems (Chemraz O-rings).
Each system includes:
- (1) High-performance HPLC reservoir
- (1) 4-valve cap
- (1) Solvent pickup adapter with PTFE tubing
- (10) 1/4-28 nuts for 1/8in. o.d. tubing
- (10) Ferrules for 1/8in. o.d. tubing
- (2) Vacuum adapters, 1/4-28 to 1/4in. i.d. tubing
- 10ft PTFE tubing, 1/8in. o.d.
- (2) 25m SS filters
- (1) PTFE coated stir bar
- (2) Adapters for 1/4-28 to 1/8in. i.d. tubing (for Waters HPLC
systems with 1/8in. tubing)

Economy HPLC systems with
three valve caps
These systems allow for the sharing of one filtration/degassing
cap assembly (sold separately on next page) with several solvent
reservoirs. A simple cap change is required between the filtration
and sparge/delivery operations. Available as standard (PTFE/PP
O-rings) or THF-resistant systems (Chemraz O-rings).
Each system includes:
- (1) High-performance HPLC reservoir
- (1) 3-valve delivery cap
- (8) 1/4-28 nuts for 1/8in. tubing
- (8) Ferrules for 1/8in. o.d. tubing
- 10ft PTFE tubing 1/8in. o.d.
- (2) 25m SS filters
- (1) PTFE coated stir bar
- (2) Adapters for 1/4-28 to 1/8in. i.d. tubing
(for Waters HPLC systems with 1/8in. tubing)
