LC ACCESSORIES
Mobile Phase Accessories
Bubbles in an LC system can cause
check valve malfunctions and pump
cavitation, seriously affecting pump
performance. The debubbler removes
bubbles from the fluid stream before it
enters the pump.
Special geometry at the base of the housing allows bubbles
entrained in the inlet fluid stream to rise and be trapped in
the reservoir. The gas/liquid interface is easily visible through
the translucent wall of the device. Loosening the airtight cap
releases the trapped gas. The debubbler features a polypropylene
body and bracket; universal inlet and outlet connecting tips are
made of 316 stainless steel and accept 0.063" , 0.085", and 0.125"
ID tubing.
Low-Pressure Slip-On Inlet Filter
for Mobile Phase Reservoir
A 316 stainless steel tip with a Tefzel® collar seals to a corro-
sion-resistant 316 stainless steel filter element. The slip-on filter
easily attaches to the pump inlet line, without the use of wrenches.
The universal 1/8" OD tip accommodates standard PTFE tubing
inner diameters.The cylindrical filter is standard 10 µmporosity.
Fits Altex, ISCO, LDC, Varian, Waters, PerkinElmer, and other
pumps.

Mobile Phase Sparge Filters
The sparge filter is an inexpensive way to
prepare and maintain mobile phases free
of dissolved gas. Filters are made from
316 stainless steel and PEEK, and they are
compatible with most solvents. Connects
to standard 1/8" OD (3.2 mm) PTFE tubing.

MiniPulse Pulse Dampener
• Compact unit (2.5" x 1.5" ) can be
placed almost anywhere.
• Small, 160 µL dead volume at
atmospheric pressure.
• PEEK unit can withstand pressures to
5,000 psi (34,474 kPa).
• 316 stainless steel unit can withstand pressures
to 6,000 psi (41,369 kPa).
Improve system baseline stability while increasing the total
system volume by only 160 µL. The MiniPulse pulse dampener
is ideal for applications where minimizing the total system vol-
ume is critical. Stainless steel and PEEK options for a wide range
of applications.

Last Drop Filter
The flat filter element sits parallel to the
bottom of the mobile phase reservoir,
allowing the filter to draw 98% of the
mobile phase without drawing air into
the system. Conventional cylindrical mo-
bile phase filters begin to draw air into
the system when approximately 10% of
the solvent remains in the reservoir. The
Last Drop filter allows more analyses per
batch of mobile phase and helps reduce
hazardous waste. 22.1 mm OD.

UHP Pulse Dampener
The UHP pulse dampener provides
minimal flow pulsation at system pres-
sures up to 18,000 psi. Its low dead vol-
ume (220 µL at atmospheric pressure)
reduces overall system volume for UHP
applications. The UHP pulse dampener
has a stainless steel fluid path.
Specifications:
Operating Pressure: 0–18,000 psi
Pulsation Dampening: 3:1 reduction in pulsation (dependent on pump characteristics
and system volume and pressure)
Fluid Path Volume: 220 µL (atmospheric pressure)
+44 µL (per 1,000 psi system pressure)
Wetted Materials: 316 SS; PTFE
Dimensions: 2.5" diameter x 2.0" high
